What I'm looking for

I'm looking for a fast-paced startup where I can own fullstack development and build 0→1 products end-to-end. I've done this before, scaling a platform to 2000+ users across 5 enterprise clients as a founding engineer. I thrive on hard problems: architecting scalable systems, optimizing performance, and shipping fast without breaking things.

I build B2B SaaS products from zero to production, and I do it with minimal oversight. Over 3+ years, I have taken vague business problems and turned them into shipped software using TypeScript, React, Next.js, Node.js, MongoDB and MySQL. I also design in Figma and Framer, so one person covers product design, frontend, backend and deployment.

At ContractSPAN, I led the architecture of a contract lifecycle platform now used by 2,000+ users across 5 enterprise clients, running at 99.8% uptime.
