About Me

Backend Software Engineer focused on automation, API integrations, and scalable systems. I design backend services with Python, Node.js, SQL, and cloud APIs to connect fragmented business platforms into reliable operational workflows.

My recent work includes backend platforms supporting 8K-12K daily transactions, automation flows that removed ~3 hours/day of manual reporting per analyst, ETL pipelines that cut processing time by ~40%, and API optimizations that improved response times by 35-40%.

I operate across architecture, implementation, and systems governance to turn finance, operations, and reporting bottlenecks into measurable backend systems with real-world usage.
