Engineering philosophy
With 4+ years of production experience, my engineering philosophy centers on architectural resilience, strict data integrity, and deterministic system behavior. From architecting end-to-end enterprise ERP backends to managing distributed crawler fleets and LLM agents, I build maintainable services designed to thrive under heavy concurrent load.
Proficient in designing AI agent architectures and leveraging advanced LLM orchestration tools to build intelligent, production-grade workflows. Passionate about solving structural challenges and building high-performance, AI-driven solutions.
