I thrive on creative challenges and exploring cutting-edge technologies, but I believe innovation requires rock-solid foundations. I build type-safe, scalable systems using code generators from OpenAPI specs and sometimes create unified FE/BE modules for seamless integration. My monorepo-first approach and full-stack expertise enable me to design BE interfaces optimized for FE needs while crafting FE experiences that maximize BE performance.

With deep roots in iOS and Android development since 2012, I bring native mobile thinking to every project. I don't just make websites responsive—I create experiences that feel native on every device, understanding the unique constraints and opportunities of mobile platforms.

I can't stand repetitive tasks and automate everything possible, leveraging AI to work smarter. When I see colleagues wasting time, I find ingenious solutions to their problems. While AI can make code work, I specialize in refactoring it to be efficient, secure, and maintainable—that's where human expertise shines.
