What I'm looking for

I'm looking for remote product engineering work where I can own Angular, Node.js, and NestJS features from technical design through deployment, improve long-running production systems, and contribute to cloud infrastructure and integrations.

I've built and maintained production platforms for XILO/Corza Technologies, eSign.com, ENISQ, and Otentico using Angular, TypeScript, Node.js, and NestJS. My work spans complex insurance workflows, document and PDF processing, education products, reusable component systems, REST integrations, and production issue resolution.

At ENISQ and Otentico, I independently designed and maintained complete production infrastructure, including cloud hosting, containerization, web-server configuration, deployment automation, CI/CD, and operations. I bring 15+ years of software development experience across frontend architecture, backend services, performance optimization, security work, and long-running product maintenance.
