About Me

A quick overview of my engineering leadership, system architecture experience, and background.

Engineering Philosophy & Background

I am a Sr. Software Engineer focused on designing resilient distributed systems, event-driven architectures, and production AI agent workflows. My journey began in comprehensive full-stack development, evolving into backend infrastructure leadership, database performance engineering (reducing complex PostgreSQL multi-facet queries from 40s to <6s), and autonomous LLM orchestration using FastAPI and Next.js. I champion Clean Architecture, SOLID principles, zero-downtime releases, and developer mentorship — aligning engineering excellence directly with measurable business velocity and client satisfaction.
