I build scalable full-stack platforms and high-throughput backend services.
ColombiaWhat I'm looking for
I've built enterprise privacy services at OneTrust using Python and Rust, supporting over 10 million monthly compliance events while reducing API latency by 35%. I also built Rust consent-processing microservices that improved throughput 3.8x and reduced infrastructure costs by 20%.
At Techvera, I built a multi-tenant SaaS platform with Python, FastAPI, Django, React, and TypeScript, increasing customer onboarding completion by 30%. At Simetrik, I built financial reconciliation services processing more than 18 million transactions daily and reduced processing time from several hours to under 45 minutes.
I enjoy taking products from greenfield ideas to reliable production systems through backend architecture, cloud-native development, testing, and close collaboration with product and design teams.
