What I'm looking for

I'm looking for a remote role where I can build backend-heavy production systems, own APIs and integrations, and deliver full-stack features with Node.js, TypeScript, React, and PostgreSQL.

At RexSoft, I delivered end-to-end functionality across SaaS, adtech, logistics, and payments products, owning backend architecture, data models, APIs, integrations, testing, and deployment. I built Stripe billing for a B2B marketplace, Trade Desk forecasting and synchronization, and real-time messaging and document-processing services.

I've built and maintained 10+ production systems using Node.js, TypeScript, React, PostgreSQL, Redis, and AWS. I also publish html-pdf-lite, a Chromium-free HTML-to-PDF package for Node.js with 6k+ total npm downloads.
