Hello, I am a

Full-Stack Software Developer.

Full-Stack DeveloperClean Architecture • API Performance • Scalable Systems

I am a Full-Stack Developer focused on building scalable web applications with clean architecture and high-performance engineering principles.

I develop end-to-end solutions across the Next.js, React, Node.js, and Python ecosystems, covering frontend interfaces, backend services, database design, and API architecture. My work goes beyond writing code that simply works; I focus on building systems that are measurable, maintainable, and reliable in the long term.

An engineering approach that creates technical value

Through API optimization, rate limiting, solid SQL database design, test-driven development, and SOLID principles, I design reliable, readable, and long-term maintainable systems.
