What I'm looking for

I'm looking for opportunities to build ambitious products using modern React or React Native stacks. I want to join a team where I can contribute not just code, but also to product strategy and system design. I am eager to apply my background in maintaining live SaaS applications to help scale complex UIs, optimize performance, and solve real user problems

I am a Remote-Native Developer with over 5 years of experience shipping high-performance web applications. My core strength lies in the Frontend ecosystem (React, Next.js, Tailwind), where I obsess over performance, pixel-perfect implementation, and UX.

Beyond just writing code, I bring a product-owner mindset to my work. I currently maintain independent SaaS projects in production serving B2B clients, which has sharpened my ability to build scalable, maintainable architectures without over-engineering. I understand that code must serve the business, prioritizing predictability and stability.
