I'm a Backend Software Engineer specializing in building high-performance, scalable systems using the Golang ecosystem. I design robust architectures and solve complex backend challenges to deliver efficient, secure applications that drive real business value.

I approach every project with a product developer mindset—understanding business needs first, then building the right technical solution. Whether it's B2B platforms or B2C applications, I focus on creating products that users love and businesses can scale.

Currently working on mission-critical backend systems at a fintech broking company, where I architect solutions that handle high transaction volumes, ensure data integrity, and maintain 99.9% uptime.

I'm a passionate and curious engineer who believes the best code solves real problems for real people. My mission is simple: build systems that not only work flawlessly but also create genuine impact in people's daily lives.
