Simon Depelchin
Senior Full Stack Developer with 15 years of experience building scalable web applications, with a strong focus on React, TypeScript, and frontend architecture.
I specialize in building modern, maintainable SaaS platforms where usability, performance, and developer experience matter as much as functionality. Over the years, I’ve led frontend initiatives, designed shared architectures and design systems, and helped teams ship products used by millions of users.
I enjoy working in small collaborative teams where ownership is high and technical decisions have direct product impact. Beyond implementation, I care deeply about intuitive interfaces, code quality, and creating systems that remain easy to evolve over time.
