01. About Me
I am a passionate Full Stack Developer who enjoys solving complex challenges, architecting robust backend databases, and building smooth interactive frontend systems. Over the past 3+ years, I have worked with multiple businesses to build and modernize their web assets, handling CRM implementations, automated lead lifecycle systems, and social content generators.
My approach is rooted in product engineering—writing clean, maintainable TypeScript code, setting up scalable microservice environments, and leveraging vector databases to construct intelligent AI solutions. I believe in taking ownership of products from discovery phase to server monitoring.
