The majority (90%?) of Frontend jobs in the Netherlands require React. Why is React so popular? I heard that React is much simpler than Angular, do you agree? If we consider not just the React core, but the required modules as well, is it really much simpler? Is this the only reason why React is so much more widespread in vacancies compared to Angular or Vue?

Hello LinkedIn, Between May 21st and May 28th I'll be visiting the Netherlands and Germany as a tourist. Since I'm #OpenToWork for the past few days, if there is a Front-End (React, React Native, TypeScript) related role that you or someone you know needs to fill, let's connect! Maybe we can meet! #react #reactnative #typescript #nextjs #mobile #web #frontend

GDP per capita between Sweden and Netherlands are quite close. Netherlands (62K USD) Sweden ( 56K USD) However, software engineering salaries are not that close. Sweden considered tech unicorn of Europe but with the weak krona and limited salary bumps software engineers are earning less and less after covid.

LinkedIn, your "AI" autocompletion for commenting on posts just started giving me recommendations in Dutch. I never spoke Dutch. I probably never will. How about some unit tests in your features, huh? Quick reminder: AI models are *statistical* models. If they work 95% or 90% of the time, that's 5 or 10% of failures. Add those numbers to your calculations for bounce rate, churn, whatever... do the math. It's expensive. My philosophy is: always use AI models with a fallback for when they fail, and never make the whole feature completely useless, even when the AI fails. The cost for failing must be very low. In this case, your failure to even detect my language (you have them in my profile?!) cost you this post. Not sure how expensive that is, but hey, bad publicity and all.

𝗔𝗿𝗲 𝘄𝗲 𝗰𝗼𝗺𝗺𝗶𝘁𝘁𝗲𝗱 𝘁𝗼 𝗽𝗿𝗼𝘃𝗶𝗱𝗲 𝘁𝗵𝗲 𝗯𝗲𝘀𝘁 𝗨𝗫? As a front-end developer, I think I'm committed to providing the best user experience. However, as a user, I often encounter irrelevant data or, worse, errors. Recently, I was tasked with creating a postcode validation system for all Dutch postcodes for one of my clients. Initially, I implemented a simple 𝙍𝙀𝙂𝙀𝙓 expression to check if the postcode was formatted correctly. During development, I realised that some postcode combinations were non-existent, leading to empty data streams. This observation led me to enhance the validation process. Instead of just verifying the format, I decided to validate the existence of the postcode before the user clicks the "𝙎𝙚𝙖𝙧𝙘𝙝" button. This approach ensures that users always receive relevant results when searching for a location. To achieve this, I utilised a combination of a REGEX expression and the GeoNames free API.

On the verge of the #Amsterdam skyline this evening as I am picking up badges for myself and Eden Katabi and Stav Elmashally for #jsnation and #reactsummit, I think to myself of the implication of technology, and indeed AI, in our everyday lives. AI is powerful, and can do some crazy things, like stealing Scarlett Johansson's voice and plagiarizing proprietary art; but is yet unable to do some basic things, like helping a friend out of a bad trip, or hanging laundry. aiOla , for instance, is creating a voice AI solution that could take your enterprise from zero to hero, just like that. We prove that AI doesn't have to be a faceless API; that it could, in fact, learn your jargon and improve your working efficiency by like, a lot. It is also a good place to work in.

It’s common for mid-level developers to overcomplicate things that could be simple. The transition from junior to senior involves a lot of learning and applying new concepts, which often leads to over-engineering. With experience we realize that not everything needs to be abstracted and simplicity often leads to the best solutions

Just wrapped up another Kotlin training for a great group of developers at Albert Heijn last week. This time, I ran it with my colleague M. Masood Masaeli. It was hands-on, and we covered the essentials—Object Orientation, Testing, Null Safety, Functional Programming, and Kotlin + Spring Boot. It’s always interesting to see how quickly developers can adapt and apply new concepts. These sessions are a good reminder of how much value we can add by building skills that directly impact our work. Looking forward to seeing how these new Kotlin tricks evolve in our apps. #kotlin #springboot #functionalprogramming

🎤 I'm speaking again today (07.05) at #HelsinkiJS and discussing how the stateless first architectural choice for frontend development aids in making your life easier 🛠️ for implementing robust, loosely coupled tests for your code. As part of the talk, I will be going through why this approach makes your frontend code more maintainable 🔄 when considering refactoring and updating your codebase in the future. Additionally, I'll be showing a basic introduction to how to use testing-library to test the frontend code.

Just rewrote Stakpak in Rust and what a journey it's been! 🦀 Learned tons about memory safety, performance optimization, and why the borrow checker is actually your best friend (after a few heated arguments 😅). The outcome? A supercharged Stakpak that's not only blazingly fast but pushed me to become a better engineer along the way. 🚀 📖 Check out the blog post for the full behind-the-scenes story!

Do you really think that Leetcode and its companions are suitable to assess the knowledge of a medior/senior? This is a huge misconception, I experienced it myself as both a professional recruiter and a candidate. A targeted interview is much more suitable, or practical exercises such as Coding Challenges. #softwaredevelopment #recruitment #donothumiliatetheexpert

Have you ever heard of the golden cage phenomenon? For me, first thing that pops into mind is tech salaries. To explain this let's talk about how it in my opinion relates to compensation tiers in the Netherlands. First let's pull up a great blog by the Gergely Orosz: https://lnkd.in/enaUkC6S. It's worth a full read if you're interested in learning more about tech compensation in the Netherlands. I'll give my short summary here. The blog describes the trimodal nature of tech salaries in the Netherlands. In short, companies active in Netherlands can be put into one of three tiers of compensation for tech: Local Champions (Albert Heijn, Coolblue), Global Players (Adyen, Miro, Nike), and Big Tech (Uber, Booking, Amazon, Netflix). For more examples, check out the blog. Compensation can be wildly different between tiers, where second tier compensation can be 2x of that given in tier 1 and tier 3 can go up to 5x. In my opinion working for one of these "Big Tech" companies can become quite the golden cage. If you're able to get in, working for one of these companies usually comes with very high total compensation (€250k total comp a year is not unheard of check: techpays.eu). In addition these companies usually offer great secondary benefits like catered lunches, free gym access, contribution to health care, etc. And you'll probably be working with the best suited hardware and tech stack for the job. However, it also tends to come with very high internal competition (e.g. for promotions), worse work-life balance (no 9-5 for sure) and generally less job security (PIP anyone?). I'm not even mentioning the fact that with the job market as is, it might not be easy to find another job for a comparable salary. Making it a golden cage. One category I didn't mention but is a honorable mention: start-ups. This is probably the place where you won't get great a great base salary, but might get some meaningful equity. However, given that most startups fail the equity might never be worth something. Hence total compensation is difficult to determine. Therefore, it's a gamble that has a slim chance to pay-off big time. But if you're seeking stability and a healthy work life balance, stay away. It's well known that start-ups can be a stressful place to work that put a high demand on you. Nevertheless, having worked in a startup does give you a unique perspective. In my opinion it's all a delicate balance between many factors, where compensation is just one of them. Having a family for me work-life balance is more important, but this might be dependent on your life stage. My advice, stepping out of a golden cage into something different (entrepeneurship, freelance, startup, local champions) can be great options, it's just a matter of what's important. What is your take on all of this? Curious to hear your thoughts. #goldencage #compensation #techsalaries #bigtech #Netherlands #tech

The biggest lie developers tell themselves? "This will only take me a couple of hours." then it turns into 2 days, maybe even a whole week Sound familiar? We’ve all been there, giving a quick estimate only to realize that those two hours have turned into two days. It’s a common trap. Here’s a better approach: Next time you feel like giving an estimate, take a moment. Step back and ditch the instinct to overpromise. Take that number – say, 2 hours – and multiply it by 1.5 or even 2. And then, for good measure, bump it up to the next realistic time unit. So 2 hours becomes 3 days. Not because the task is that hard but because it’s never just coding. With this extra space, you can: - Map out a plan - Tackle unexpected bugs - Test without stress (locally *and* in staging) - Do proper reviews and quality checks - Actually have time to fix issues, not just patch them And here’s the payoff: You’ll avoid last-minute rushes, deliver something you can actually be proud of, and even leave a bit of buffer time. Every developer knows what it’s like to watch a simple task balloon out of control. This method doesn’t just keep you honest – it keeps you sane and your team and future self will thank you for it :)

🔴 It was September 2018 last time I worked with Angular.js (1.x). 🆖 Few weeks ago, I was asked to develop a solution via NgRx for a challenge within a week, and below are the details of it; 🚀 Project: https://lnkd.in/deauKUN5 🔗 Repo: https://lnkd.in/dWRaA_ke 💼 Position: https://lnkd.in/diYBXRNV 🥲 👾 PS: I passed the second round with the repository above, but unfortunately, I failed the next rounds. I'll be happier if anyone learns anything from my contributions. --- Don't forget to 👍 Like 💬 Comment ♻ Repost 📬 Send or 💾 Save this post 🔔 Follow me for more content like this #opentowork #angularjs #ngrx #nextjs #reactjs #softwareengineer #frontenddeveloper #fullstackdeveloper #mentor #frontendarchitect #leaddeveloper #statemanagement

I decided to give Strapi a shot and add it as the CMS for my website. As expected, that increased the loading time (you know, it's always a trade-off), so I thought that it was a good opportunity to learn more about Skeletons. My findings so far: • Skeletons should match the size, shape, and layout of the final element—to prevent layout shifts. • Use lightweight animations, and avoid overloading the DOM. • Ensure skeletons are responsive and accessible to all users. • Focus on above-the-fold skeletons for the best-perceived performance. • Test skeleton performance and responsiveness under real-world conditions. #strapi #cms #skeletons #frontend #development #ux
