Specialised in acoustic treatment and sound insulation, I can help you: • Designing good acoustics for your venue by helping out with measurement and/or modeling your room in 3D with an acoustic software to help finding out which design shuts you best. • Reducing noise coming to your room from outside or from next door apartments by pointing out weaknesses in your wall/facade and give advice on materials to achieve a decent living space at minimum costs.

I'm a software engineer with 8 years of experience building mobile and web applications using React, React Native / Expo, Node.js, Supabase, Firebase, and Ruby on Rails. Over the years, I've worked on more than 30 professional projects across a variety of industries, gaining extensive experience building user-facing products from idea to production. While I have a strong technical foundation, I'm also highly product-focused. My goal is not simply to write code, but to build products that solve real problems, deliver value to users, and drive actual business revenue. I believe the best products are built iteratively. Rather than overengineering solutions, I focus on identifying the core features that create the most value, delivering them quickly, and establishing a solid foundation that can evolve as the product grows. When I'm not working on client projects, I'm building my own applications. That hands-on experience of designing, shipping, and iterating on products gives me a practical understanding of both the technical and product side of software development, which helps me work effectively with founders and entrepreneurs. I work mainly with Claude Code, which allows me to develop much faster and offer competitive pricing while still delivering high-quality work. Do not hesitate to reach out to discuss your project(s)!
