Last updated: 2026-08-12. Canonical: . ## Summary Senior Frontend Engineer with 8+ years shipping production React and TypeScript across SaaS, B2B, and B2C, including three years on a payments platform. Picks work up at the wireframe and mockup stage, prototypes the interactions with product designers, and stays on it through implementation and release. Refactors legacy code incrementally while delivering new work. Strongest on the parts of a frontend that decide whether it is still workable a year later: component libraries, state management, and test suites that catch real regressions. Performance-focused — tracks Core Web Vitals, reduces bundle size and network requests, builds responsive mobile-first layouts. Comfortable in Node.js for building APIs and debugging across the stack. Also ships AI-integrated tooling: an OpenAI-compatible queue for local LLMs, an agentic scrape-and-extract pipeline, and an on-device LLM content classifier. Earlier background as a system administrator (Cisco/VLAN networking, servers, backups, scripting), which is where the CI/CD and infrastructure comfort comes from. ## Availability and engagement - **Status:** Available now. - **Sought:** Full-time remote role, 40 hrs/week.

Shipped by [Our World in Data](https://github.com/owid/owid-grapher), [Precious Plastic](https://github.com/ONEARMY/community-platform), [erxes](https://github.com/erxes/erxes), [Reapit](https://github.com/reapit/foundations), and AWS's [Performance Dashboard](https://github.com/aws-solutions/performance-dashboard-on-aws) solution. A horizontal scroll primitive for React. Inherited the library, rewrote the core in TypeScript, added tests and Storybook, and kept the public API stable through React 17, 18, and 19 — years of maintenance without forcing a breaking change on downstream users. - GitHub: - npm: - Site: - Demo (Storybook, live-editable): ### state-in-url 417 stars · ~4.5k weekly npm installs · zero dependencies. Keeps nested, typed React state in the URL, so filters, multi-step forms, and expanded panels survive a reload and can be shared as a link. Sole author: designed the hooks API, wrote the TypeScript core, built the docs site, handles every issue and release. Stable across Next.js, Remix, and React Router, and through multiple React majors. - GitHub: - Demo: ### test-proxy-recorder 99 stars. VCR-style record-and-replay testing for Playwright. Captures real API traffic once across Next.js SSR, browser, and WebSocket transports, then replays it deterministically in CI with no backend running. Solves the problem that makes integration suites flaky: tests that depend on live services. - GitHub: - Site: ### llm-queue Single-worker priority queue for local LLMs (Ollama), exposed as an OpenAI-compatible HTTP service so cron jobs, browser extensions, and OpenAI clients all share one serialized queue against a single model. Published on npm with a CLI. - GitHub: ## Commercial project case studies ### Omise — payments merchant dashboard Three years architecting and maintaining the merchant-facing dashboard for Omise's payments platform. React, GraphQL, styled-components, plus an internal D3.js analytics dashboard and a JavaScript SDK bridging a native mobile wrapper to JS mini-apps. Ran in production throughout, including across a major architecture refactor. Agreeing API contracts with backend before implementation cut rework between the two sides. ### channels.careers — B2B hiring platform Sole frontend engineer. Next.js and TypeScript UI built to match design closely, a shared-state refactor, mobile adaptation, and the Playwright suite the team gates releases on.
