Software Engineer
I am a software engineer with 2+ years of experience shipping backend systems, applied AI products, and marketplace platforms into production. My work spans distributed workers processing high volumes of financial documents through an OCR-to-LLM pipeline, event-driven services synchronizing real-time state across marketplaces, and observability layers that make production failures explainable instead of mysterious. I care about the fundamentals that top-tier product engineering teams care about — throughput, latency, correctness under concurrency, and clear system boundaries. Outside of work, I keep sharp by tinkering with AI and practicing competitive programming.
I move comfortably across the stack, but I do not define myself by one layer of it. What matters more is understanding the problem, reasoning from its constraints, and leaving the system a little more correct and a little clearer than I found it. Applied AI, distributed systems, and competitive programming are the three threads that keep pulling me back in.
