about meAbout
I'm a Software Engineer focused on building reliable product systems. I design APIs, backend workflows, and scalable application architecture that connect business goals with strong technical execution. My work spans: video platforms, professional networks, behavioral intelligence systems, and mobile-first products. I care about performance, maintainability, product clarity, and building software that is simple enough to evolve and reliable enough to support real users.

I design and build software product systems that are reliable, scalable, and maintainable. My work includes performance optimization and integrations across web and mobile platforms. I enjoy working close to product problems: understanding user needs, shaping technical direction, and turning unclear requirements into systems that teams can confidently build on.
