Engineering profile

Senior AI & Frontend Engineer operating at Staff scope.

Engineer with 13+ years of experience shipping production software, currently building AI product features at Writer, an enterprise generative AI platform. Deep in two areas most teams struggle to combine: making AI features reliable enough for enterprise production, and keeping complex React/TypeScript platforms fast and maintainable. Previously led a frontend engineering organization at MEGOGO and built high-stakes interfaces for autonomous driving (Zenseact/Volvo Cars), network security (Cato Networks), cross-platform plugin ecosystems (LottieFiles), and Web3 wallet and DEX products (CTRL, Unizen, OneArt, HookRank).

Core strengths

What I’m strongest at.

AI product engineering

Agent workflows, RAG and grounding, knowledge connectors, and the production UX around AI — built daily at Writer since 2023.

Frontend systems & performance

React/TypeScript platforms with real complexity: state architecture, typed boundaries, rendering and bundle performance, incremental modernization — measured with a profiler, not guessed.

Integrations & identity

OAuth, SSO/SCIM/IdP provisioning, webhooks, and API reliability patterns — the systems enterprise deals depend on.

Plugins & extensions

Production plugins across Chrome, Figma, Adobe, Canva, VS Code, and WordPress ecosystems, each with its own sandbox and constraints.

Web3 & wallet products

Multichain wallet browser extensions, DEX and swap UX, NFT flows, and subgraph-backed analytics — shipped across CTRL, Unizen, OneArt, and HookRank.

Technical leadership

Led a frontend engineering organization at MEGOGO; mentoring, architecture direction, and delivery predictability since.
