What I'm looking for

I'm looking to build high-impact full-stack products where I can own interfaces, APIs, performance, testing, and reliable data-driven workflows.

At Pioneer Dev AI, I build and maintain data-intensive products across React, Remix, Prisma, PostgreSQL, Astro, and Cloudflare. I own frontend infrastructure for an operator management system and set component, state, and code standards.

I migrated 206 files from Remix v2 to React Router v7 and Prisma v6 to v7, backed by a Vitest regression suite. For FilipinaMeet and SlavicMeet, I rebuilt Webflow landing pages into a multi-brand Astro architecture serving 40,000+ users and resolved recurring explore outages through de-indexing and server-side loader caching.

I also build conversion-focused systems, including a multi-step lead funnel for MatchGuarantee that captured 18 new leads, integrated CRM and Meta Conversions API events, and reduced conversion over-reporting from 14 events per lead to one. At Yield Food Intelligence, I improved Prisma query and caching performance from 5–10 seconds to 100–200ms.

I enjoy shipping practical tools end to end, from interface systems and APIs to performance, testing, analytics, and security. My open-source Neovim and Go work has earned 100+ community upvotes and 16 GitHub stars.
