What I'm looking for

I'm open to remote opportunities and relocation to the EU where I can build reliable backend or full-stack products, solve production-scale problems, and continue growing through collaborative engineering work.

At BuildMate, I build TypeScript and Node.js systems for construction-company procurement, including dashboards that support 40,000+ records per client and synchronise 55,000+ daily records from Sienge. I also contained a critical WebSocket production incident, cut AWS costs by 48%, and eliminated backend instability and 500 errors.

I've improved a critical Node.js and PostgreSQL routine by 98% while eliminating weekly deadlocks, mentored two interns through promotion to Junior Developer, and built reusable bulk-processing infrastructure on AWS S3. Outside work, I publish open-source Express tooling on npm and built EncurteAI, a full-stack URL shortener with expiration automation and API rate limiting.
