What I'm looking for

I’m looking for full-time remote roles where I can own 0-to-1 product delivery end-to-end—frontend, backend, and infrastructure—using React/Next.js and strong engineering practices, with room to lead teams and ship at scale.

I’m a Senior Full-Stack Engineer with 6+ years building and shipping complete products from 0 to 1—owning frontend, backend, infrastructure, and delivery. I’ve shipped platforms serving 350K+ users at $1M+ transaction volumes, with mobile apps live on 3 app stores, and enterprise systems featured in national media.

I lead by pairing system design and delivery discipline with hands-on execution. As Founder & Engineering Lead for Lupply, I founded and led a team of 5+ engineers and shipped a cross-platform Flutter mobile app plus a dedicated Windows desktop app, fully owning the product lifecycle from architecture to code reviews and TypeScript standards. I also built high-traffic backend infrastructure for a cross-chain DEX aggregator ($1M+ trading volume, 300K+ users) and reduced API response times by 80%, while delivering full-stack experiences that generated 142+ contact submissions, 10+ talent applications, and handled launch-day server surge with zero downtime.
