About

Systems that scale don't build themselves — and I spend my time making sure they do. I'm a backend and data engineer with experience designing distributed systems in C++, building production data pipelines on GCP, and engineering automation that eliminates manual overhead at scale. At Cognizant, my Python-based frameworks reduced manual effort by ~90% across data workflows. Before that, I built a distributed reverse proxy in C++ — handling concurrent connections, HTTP parsing, and load balancing from scratch. I work at the intersection of backend engineering and data infrastructure: Languages: Python, C++, SQL Data Stack: BigQuery, Airflow, GCP, ETL Backend: Flask, REST APIs, socket programming, concurrent systems I'm looking for engineering roles where the technical bar is high. If you're hiring for backend or data roles, let's talk.
