Full-Stack Developer
Transforming complex problems into elegant, scalable solutions
01 / ABOUT ME
I am a technology professional who bridges the gap between full-stack engineering and applied AI. With hands-on experience building scalable, multi-tenant SaaS platforms and AI-powered systems, I specialize in crafting intuitive digital products that solve real-world business problems and deliver measurable impact.
Across my work, I've owned projects end-to-end—translating business requirements into production-ready systems, working with modern frameworks like React, Next.js, and NestJS, and integrating AI capabilities such as RAG pipelines and vector search to make software smarter and more useful. I bring a strong focus on clean architecture, performance, and scalable design, while always keeping the end user's experience at the center of what I build.
