What I'm looking for

I'm looking to build reliable, high-performance backend and platform systems, particularly distributed control planes, PostgreSQL tooling, deployment automation, and operationally simple infrastructure.

At Diasoft, I've architected a distributed PostgreSQL control-plane and agent platform across nine Linux distributions, reducing deployment time from two hours to 10 minutes. I also built a browser-based real-time psql terminal and logical replication monitoring for PostgreSQL 10–17.

Previously at Tensor, I led a zero-data-loss INT32-to-INT64 migration in a multi-terabyte PostgreSQL environment, rolled out document workflow and e-signature support, and optimized CRM, XML reporting, and social-media integrations. Across six years in Python, PostgreSQL, and production infrastructure, I focus on reliability, performance, and operational simplicity.
