What I'm looking for

I'm looking for contract or full-time remote roles with EU or US time-zone overlap, where I can build reliable backend integrations, real-time data systems, and production LLM features.

I've built reliable backend integrations and real-time data systems for Invozone, Frontline Services, BlackStone Cooperative Initiative, and remote clients. At Invozone, I architected a Node.js and PostgreSQL patient-data synchronization platform processing 50,000+ records daily at 99.9% uptime.

I'm now building SyncSentry to catch broken Shopify webhook and API syncs before merchants lose orders, while shipping Claude-powered content workflows that reduce half-day manual work to about 15 minutes. I enjoy designing API contracts, reverse-engineering undocumented vendor APIs, and keeping production systems dependable on AWS and Docker.
