What I'm looking for

I’m looking to build and scale resilient, high-throughput distributed systems—leading cross-functional delivery, improving CI/CD and observability, and mentoring engineers to maintain uptime and throughput.

I’m a Senior software engineer with more than 10 years building high-throughput distributed systems and transactional platforms. I design resilient architectures, lead cross-functional teams, and mentor engineers to improve delivery and quality, with a strong focus on uptime and throughput.

I build full-stack features and APIs using Python, Flask, and React, optimizing data models on PostgreSQL for scale and reliability. In recent roles, I led a modular payroll API platform that reduced nightly batch runtime by 65% and delivered 1.2M requests per day with p95 latency under 120ms, and I built real-time communications services reaching 99.95% availability while cutting downstream processing lag from 14 minutes to 90 seconds. I also drive CI/CD, observability, and incident response practices, using AWS and modern DevOps tooling to keep systems running smoothly.
