- If you've known us even for a little while, you know that we're huge fans of Java and JavaScript. And for good reason! They're some of the most powerful languages out there, but as a wise man once said, 𝘸𝘪𝘵𝘩 𝘨𝘳𝘦𝘢𝘵 𝘱𝘰𝘸𝘦𝘳 𝘤𝘰𝘮𝘦𝘴 𝘨𝘳𝘦𝘢𝘵 𝘳𝘦𝘴𝘱𝘰𝘯𝘴𝘪𝘣𝘪𝘭𝘪𝘵𝘺. For example, JavaScript is a great tool for building applications. But because it’s mostly used for web applications, you’ll need to be extra careful when it comes to security. To help you out, we’ve listed four basic habits that should be part of your
- When Kenneth and Iderisse wrapped up Matt Pocock's AI Coding Crash Course, they came back with one clear verdict: everyone at Optis should take this. 💻 So we went for it. Kenneth and Iderisse picked out the parts that matter most, added their own explanations and walked everyone through them. 👉 The course takes you through 𝗔𝗜 𝗰𝗼𝗱𝗶𝗻𝗴 from the ground up. You start by getting to know the engine. How does a language model work, what does a harness like Claude Code actually do behind the scenes, and why does your agent get
- Angular, React, or Vue? 🤔 Many JavaScript projects start with that question, and the answer affects more than the codebase. It decides how fast you ship, what maintenance costs down the line, how well the app scales, and how efficiently your development team can work. 𝗔𝗻𝗴𝘂𝗹𝗮𝗿 brings structure and long-term stability. 𝗥𝗲𝗮𝗰𝘁 brings the biggest ecosystem and the most flexibility. 𝗩𝘂𝗲 lands somewhere in between, real freedom paired with defaults that keep teams from starting on a blank page. The right framework depends on

- From a successful internship straight into a full-time job: say hello to our newest developer, Siebe De Vos! 🚀 Siebe first connected with us during a campus event at Karel de Grote Hogeschool, where the 'click' with our team made him pick Optis for his internship. During those months, he built an internal training budget application from scratch using React, Java, and AWS, tackling everything from security flows right down to deployment. Not an easy task, but he handled it like a pro! Now that he has officially joined our ranks as
- Q4 is right around the corner, and you know what that means: things are about to get busy! With the end of the year approaching, it’s a good time to look ahead. Processes to improve. Software projects that have been on the roadmap for a while. But what if you don’t have the internal capacity to make it happen? 🤷♀️ That’s where the 𝗢𝗽𝘁𝗶𝘀 𝗙𝗮𝗰𝘁𝗼𝗿𝘆 comes in. Instead of a single developer, this gives you a whole team of Java and JavaScript specialists who take full ownership of your software. From planning and
- We talk a lot about building great applications, but the real secret is the people writing the code. And sometimes, those people also need a cache clear. 😉 To close out the summer, we brought the members of the #OptisFamily together, including their actual families! We kept it simple: good food, cold drinks, and great company! After all, building software is a team sport, but building a great team happens just as much away from the screen.🌞 Now that everyone is refreshed and refuelled, we're ready for whatever Q4 throws at us!
