01. About Me

I'm a senior backend engineer with 8+ years of experience building high-performance distributed systems. Currently at Amazon as SDE II, I focus on AI-powered Oncall optimization and building intelligent memory systems that help teams work smarter.

My core strength is in Golang backend development โ€” from designing device management platforms handling 500K+ concurrent connections to architecting e-commerce systems sustaining 50K QPS during peak sales. I'm passionate about applying AI to solve real engineering problems.
