About Me

I'm a Software Developer at Josh Technology Group, building and scaling cloud-native systems on GCP. My day-to-day involves production systems that process billions of operations, real-time data pipelines, and making sure things stay fast and affordable at scale.

I care deeply about clean architecture and shipping things that actually work. Outside of work, I stay sharp through competitive programming — currently a LeetCode Guardian (Top 1.02% globally) and active on Codeforces for algorithmic problem solving.

Always curious — exploring GenAI, LLMs, RAGs, Vector DB, digging into the Lightning Network, or contributing to open source. Let's build something together.
