ABOUT
Fullstack developer (TypeScript, React/Next.js, Node.js) with 4+ years of commercial experience across consumer
products, internal tools, and the occasional Web3 integration. I gravitate toward work that makes the team
faster: performance optimization, build tooling, and libraries that hold up six months later. Comfortable
bootstrapping a new project from scratch or going deep into an existing codebase, including less typical work like
canvas-based editors.

EXPERIENCE
3look 04/2024 — Present
• Extended a Konva canvas editor where users compose animated GIFs by placing curated or custom-uploaded
faces onto templates. Shipped custom uploads, text editing, and recently-used assets, plus fixes for cross-
browser and device-specific UX bugs.
• Led a monorepo performance and DX cleanup. Retuned tsconfigs to fix TS server stalls in the shared backend
package, and pruned bundles via next/bundle-analyzer and knip, which unblocked shared-package work and
sped up pages.
Technologies: TypeScript, React, Next.js, Konva, Tailwind, NestJS, Docker, PostgreSQL, Prisma.

Pragmatic DLT 04/2023 — 03/2024
• Built a battery lifecycle management web app from scratch for an outsourced client, used by their team to
manage orders and by their customers to track repair, recycling, and renewal status.
• Designed a natural-language movie search tool. OpenAI rewrote user queries into Elasticsearch queries
against a corpus of dialog transcripts, letting users search by what was said rather than by title.
Technologies: TypeScript, React, Next.js, tRPC, Tailwind, Docker, Elasticsearch.

dZENcode 09/2022 — 04/2023
• Created a gRPC microservice that scraped data from an external source and used the OpenAI API to generate
email drafts delivered through Outlook. It was the team's first step toward incorporating LLM-driven
workflows into their backend.
Technologies: TypeScript, Node, Python, Django.
