So much for the basement-dwelling programmer stereotype 😉. Conferences like the International PHP Conference are splendid opportunities to gain new perspectives - and face new challenges. 🛠️ Programming is essentially about solving problems, and events just like this conference allow us to share experiences and learn from best of the best in the industry. During sessions and workshops, I got to hear real stories about real problems - how they arise, how to solve them - and how to prevent them from reoccurring. 😉 I had the pleasure of attending talks on the latest trends in PHP, code optimization and best practices in system architecture. I learned how to avoid common mistakes and what techniques to use to make our applications even more efficient and secure. 🖥️🔐 Meeting other specialists - once again - proved that exchanging insights is the key to growth. I'm glad I could be part of this inspiring community! 🤝✨ Thank you to all the speakers and participants for the incredible knowledge and motivation! 🙏📚 Topics covered: - PHP Core & Optimization [Bohuslav Šimek, Carsten Windler] - Refactoring [Ralf Eggert] - Testing, Test Driven Development, and Logging [Florian Engelhardt] - Software Architecture & Design Driven Development [Katy Ereira, Dr. Sönke J. Magnussen] - Security 🔒 - DevOps & Deployment [Nic Wortel] - Clean Code [Ondřej Mirtes] - Git Advanced & Working with abandoned Open Source Projects [Juliette Reinders Folmer]

Quick engineering salary comparison based on the #DEVBG stats from 2023 and 2024 in the Bulgarian IT industry. Dev.bg publish yearly a summary of the Bulgarian IT engineering salaries based on the job openings offers on their platform. https://lnkd.in/dNU5MD8D (2023 stats) https://lnkd.in/dX_dxvP7 (2024 stats) Based on the population data (let's assume it's a proper representation of the real world) we can determine the following: 1. PHP should be dead but it isn't (unfortunately) as it's one of the two categories with growing salaries in all job positions and ranges. 2. The second is the full stack development with a minimum drop of 65 levas in the first MID range(2-5 years) 3. All ranges except the Senior level(5+ years of experience) have a drop in salary compared to 2023 but for some seem negligible compared to the notion in the industry that "it's going down and AI will take over the world" :) 4. We can see that seniority still counts and there is now a shift towards growth of salaries of more senior people compared to others as the market tries to regulate. 5. There is still a lot of green for a "dying" and "shrinking" industry. P.S To anyone interested I can share the excel if needed but it's quite straightforward to generate it. *Legend: Diff min Mid - difference in the minimum ranges for a category between 2023 and 2024 Diff max Mid - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen - difference in the minimum ranges for a category between 2023 and 2024 Diff max Sen - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen Median - difference in the minimum ranges based on the provided median from dev.bg for a category between 2023 and 2024 Diff max Sen Median - difference in the maximum ranges based on the provided median from dev.bg for a category between 2023 and 2024

On May 8th, we have WarsawJS Meetup #114 awaiting us, featuring Tomasz Ducin on stage with a fascinating presentation titled "Back in the game: Recent Revolutionary Changes in Angular"! But today, let's reminisce about his previous appearance at WarsawJS Meetup #108 💭 In that lecture, titled "Who needs Server Components?", Tomasz delved into the next step in the evolution of web architecture. After MPAs, SPAs, SSR, SSG/ISG, it's time for Server Components! Throughout the presentation, he asked himself many questions: Does this architecture fit the needs of my business and application? What are the benefits? And are we not stepping backward by moving more operations back to the server? Breaking down the hype around Server Components, Tomasz also introduced us to some technical details regarding React Server Components. By combining client-side interactivity with server-side efficiency, we can optimize web metrics and revolutionize website development. We invite you to watch that presentation, which opened our minds to a new perspective on web development! Enjoy watching! 🍿 🎥 Part 1: https://lnkd.in/dQ7G_jFZ  🎥 Part 2: https://lnkd.in/dJzQmsQD We encourage you to participate in WarsawJS Meetup #114, where you'll have the opportunity to not only listen to Tomasz's lecture but also to other outstanding speakers live.

If you are curious on "Evolutionary Architecture" don't miss our .NET User Group Zürich May Meetup where we will cover the topic providing some lessons that diverge from "pure tech" talks. On this one, Maciej Jedrzejewski will explain How incremental developments in core engineering have enabled the foundations for enable software which can evolve over time along the architecture, protecting important architectural characteristics as it evolves. All while keeping it as simple as possible, maintainable and manageable in amount of complexity. Sounds interesting? ;) It is!! And even more if you have 5+ years of experience, chances are that you have lived a project that died because of complexity and lack of proper architectural vision (partial or... complete) - I've been there! So, how does it sound and all of this - for free!! Thanks Digitec Galaxus AG and Maciej Jedrzejewski!!! I am not going to miss it - and so should you... RSVP while you can, places are limited: https://lnkd.in/dmnnEGUZ Ah, we will have Food & Drink #architecture #software #evolutionaryarchitecture #KISS #DRY #easy #maintainable #resilience

Soon, on May 8th, we're gathering at WarsawJS Meetup #114, which will take place at the Packhelp headquarters. We've prepared a truly exceptional agenda for you with three incredibly interesting lectures! 🚀 👨‍🏫 Tomasz Ducin — Back in the game: Recent Revolutionary Changes in Angular 👨‍🏫 📝 Description: Angular has been perceived as a rather complex framework by some, yet it's used massively by enterprise-scale systems. Whether we agree with the criticism or not, the framework is undergoing a monumental transformation. In recent months, Angular is experiencing a period of frequent and significant updates and - at least considering previous years of stagnation - groundbreaking changes. These include not only the features, public API and architecture, but also to the mental models that developers come up with. 👨‍🏫 Michał Trojanowski — Securing Single Page Applications Using The Token Handler Pattern 👨‍🏫 📝 Description: Single Page Applications appear simple at first sight. Web developers provide a superb user experience, and it is also relatively easy to implement token-based security in the browser. Yet this is against current best practices for browser-based apps, and security concerns can become a blocking issue. It is instead recommended to implement a Backend for Frontend (BFF), to reduce browser threats. Yet this often results in the adoption of website technologies to issue secure cookies, which can work against other web architecture goals. In this talk, I will show how a separation of web and API concerns can give you the best choices. In the talk, I will present the Token Handler pattern — Curity's variation of the Backend For Frontend approach. I will show the open-source projects we created to facilitate the implementation of the pattern. 👨‍🏫 Tobiasz Ciesielski — TailwindCSS - Why you should have it in your project? 👨‍🏫 📝 Description: Tailwind has become the most popular styling framework. More than 8 million downloads per week via npm. Why has it become so popular? What are its advantages and disadvantages? Why did we decide to migrate to tailwind in Prowly? What are the good and bad practices of using the framework? I will answer all these questions. These lectures are not only a great opportunity to gain new knowledge but also to meet other technology enthusiasts! Don't miss out on this event! 😉 Tickets are already available, so don't wait and reserve your spot now! 👇 🔖 Tickets: https://lnkd.in/dhXVXwpf See you at WarsawJS Meetup #114! 💫 #WarsawJS #Meetup #Programming #JavaScript

Do you hire developers based on technical skills alone? It could be costing you.  Many companies make this mistake, believing that if a developer can code well, they’ll automatically thrive in the team. But this is not always the case. I have a client in Krakow who specifically hires Java Engineers who can have a “normal conversation" about software, clean code practices, and general life. But most importantly someone he can get along with. If they can do that, he’s usually ready to hire them. However, if they don’t fit culturally, it doesn’t matter if they’ve coded at Google, have an Oxbridge education, or have a long list of technical achievements. They won’t get the job. This is also not unique. According to Leaders.com, approximately 80% of employers take personality into account when making hiring decisions. Also research from Harvard Business Review found that 40-60% of hiring managers admit to hiring candidates who resemble them in terms of background, values, or attitudes. None of this mentions their skills. The ability to mesh with the team and collaborate is non-negotiable. Some people picture developers as introverted hackers, coding away in dark rooms, surrounded by empty energy drink cans. The stereotype that developers don’t need social skills in my opinion, comes from how they’re portrayed in Hollywood (Die Hard 4 was what came to mind when writing this). In reality, developers are part of cross-functional teams. They interact with product managers, designers, and other stakeholders daily. They need to explain complex ideas, collaborate on solutions, and contribute to the team’s overall culture. A developer who can’t work well with others or communicate effectively can disrupt workflows, no matter how technically gifted they are. It’s like having the most advanced software that no one knows how to use. What’s the point? The best hires are those who fit into your culture and can contribute to the team dynamic - not just those who can write the cleanest code. So if you’re only hiring based on technical skills, you might be missing out on your most valuable assets: collaboration, communication, and cultural fit. Skills get you in the door, but culture fit keeps you there. Do you take culture fit into account when hiring engineers?  #SoftwareEngineering #PolandTech #TechRecruitment #PolandJobs #CultureFit #DeveloperLife #WorkplaceCulture #TechRecruitment

📣 Presenting the full agenda for WarsawJS Meetup #117! 📣 The event will take place on August 14th at the fantastic BEC Poland headquarters. Check out what we have prepared for you: ► Robert Pasiński — Deep Dive into JS task scheduling We’ll go deep into what are tasks in JavaScript context, what is the difference between micro-task and macro-task, when they are run and how they are scheduled. I’m gonna go through the APIs like requestIdleCallback, requestAnimationFrame, and other that allow us to leverage the scheduling mechanism and highlight the bottlenecks. You can also expect a glimpse of how these are implemented under the hood in JS engines. ► Inez Okulska, — RAG vs GPTs fine-tuning - who wins? Natural language interfaces for information retrieval are very appealing. Hence, the popularity of GPTs for quick fine-tuning of GPT models. Are they reliable enough, though? When and why do we need more complex solutions like RAG systems? We’ll analyze this using the hAI Magazine case study. ► Jerzy N. — How to build real-time video processing web app Do you want to create a real-time video processing application? That's excellent, but have you considered how to handle delays, video compression, and high infrastructure costs? At ShareTheBoard, we thoroughly analyzed these challenges, tested various approaches, and ultimately succeeded in developing a web application that allows you to share digitized data with remote meeting participants. In this session, we will discuss the biggest challenges we faced and describe our final architecture. Join us to listen to experts in their fields and learn more about JavaScript, GPTs, and real-time video processing. It’s a great opportunity to gain new knowledge and make valuable connections! 🧠👥 🎟️ Tickets available here: https://lnkd.in/dtZmKC5G We can't wait to see you at WarsawJS Meetup #117! 🫂🤝 #WarsawJS #Meetup #TechEvents #WebDevelopment

🌟 The Full Agenda for WarsawJS Meetup #115 is Now Available! 🌟 We are thrilled to announce the complete agenda for the upcoming WarsawJS Meetup #115! Get ready for inspiring talks and outstanding speakers who will share their knowledge and experience. This event is a perfect opportunity to broaden your horizons in the world of JavaScript and TypeScript. Here’s what awaits you: ► Michał Miszczyszyn — The Power of Property-Based Testing in TypeScript / Strengthening Code Quality and Reliability Talk Description: Property-based testing is a technique for ensuring application correctness by generating tests based on a set of properties. In this presentation, we'll delve into the world of property-based testing in TypeScript. We'll explore how it enhances code quality and reliability, discuss the principles behind property-based testing, and showcase real-world examples of how it can uncover bugs and edge cases that traditional testing may miss. ► Szymon Mentel — Multi-tenant apps with single-tenant SQLite databases in global Tigris buckets Talk Description: Multi-tenancy is tough. Sharing resources fairly and effectively as well as ensuring secure code execution are just some of the challenges faced when dealing with the problem. But what if we approach it with single-tenant, isolated VMs mutating single-tenant database instances? Like, if a tenant’s request hits the system it gets routed to an exclusive tenant VM that uses an exclusive tenant’s database. The talk explores an unconventional architecture of homogenous Node.js servers running on top of single-tenant Fly Machines hosting single-tenant SQLite databases stored in globally replicated Tigris buckets. ► Mieszko Sabo — Type level programming in TypeScript Talk Description: During the presentation, we will look at the type system in TypeScript, approaching it as an independent programming language. I will show how we can use types to express mechanisms known from other languages, such as loops, functions, conditional expressions, etc. Are you curious about how crazy things the type system in TypeScript allows you to do and how you can use its full potential for your everyday work? After my presentation, the possibilities of the type system will become clear to you, and you will learn how you can further expand your knowledge towards programming on types. The upcoming meetup is a unique opportunity to delve into advanced programming techniques, discover modern approaches to application architecture, and unlock the full potential of TypeScript.
