I began my career in 2014 as a Web Developer for a small local business, later expanding my experience across diverse environments, from tech startups to multinational corporations. Over the years, I’ve grown technically and reshaped my perspective on work, striving to create balance and purpose in my professional life. Initially, I focused on crafting overengineered solutions that anticipated every possible scenario—even those unlikely to occur. Through experience, I learned that simplicity, combined with automated testing, is key to creating scalable, maintainable systems that can evolve over time. Midway through my journey, I embraced Agile methodology, which introduced an iterative, feedback-driven approach to development. Delivering features incrementally enables faster validation and refinement, avoiding the pitfalls of building a product nobody wants. However, effective Agile relies on transparent communication—teams must uphold the definition of “done,” resist unreasonable timelines, and openly discuss technical concerns with product owners. Throughout my journey, I’ve remained committed to building meaningful solutions that align with business goals, always seeking to combine technical excellence with practical impact.

I had the pleasure of working alongside Kong Chor at PlayStation, and I can con dently say that he is one of the most talented and dependable professionals I’ve had the privilege to collaborate with. Kong brings an exceptional combination of technical expertise, problem-solving skills, and a team- rst attitude to everything he does. His pro ciency in JS/TS stacks and his ability to quickly grasp the nuances of complex systems made him an indispensable asset to our team. Beyond his technical skills, Kong stands out for his collaborative and supportive nature. He’s always willing to lend a hand, share insights, or help other team members. I highly recommend Kong to any team or organization looking for a skilled and dedicated software engineer. He will undoubtedly make a lasting impact wherever he goes.
- Rutger HuijsmansNeat Lead Engineer
When I joined Neat I had limited experience with web development and JavaScript. Luckily, I had Chor on my team! Chor is extremely experienced in JS development and he's a very patient person. Despite the pandemic he made the effort to commute to o ce everyday to teach me the ins and outs of Neat's system face to face. He truly enabled the team to excel technically. He inspired us to use the best technologies for the job and explained them when needed. I hope to work together with Chor again in the future.
