01 2023 — 2025 Senior full-stack (protocol)

Architecting USDs V2, then closing the Quantstamp batch.

Joined Sperax to rebuild an over-collateralized stablecoin on a state-based clean slate — token, VaultCore, rebase, oracle router, collateral, Uniswap V3 strategies, with The Graph subgraphs and TypeScript/Go backends on top. Same tenure also shipped Demeter (V3 farms-as-a-service — Genesis partners GMX, PlutusDAO, Gains, Vela) and Chaquen (on-chain fantasy sports, ~27K Polygon users).

The Quantstamp batch hit the whole repo — approvals, input validation, event emission, rebase/redeem edge cases — alongside 18–35% gas reductions on hot paths.

02 2025 — 2026 Full-stack · contract

A B2B video-and-email platform, shipped end-to-end.

Restaurant-marketing campaign platform seeded by Kevin O'Leary ($1.2M, O'Leary Ventures) — media gallery, video uploads, role-based approvals, async notifications. Built across Go, Node, and React. The core upgrade swapped a Google-Drive-backed media flow for direct-to-Azure-Blob: chunked client sessions, concurrency control, fault-tolerant processing, SAS download URLs, lifecycle cleanup.

SendGrid became the email spine for video campaigns; batching and throughput passes consolidated the send pipeline onto one instrumented path. AI-assisted segmentation (chat UI + CSV bulk import) pulled manual work from hours into minutes.

03 2026 → Applied AI · solo build

An AI agent system that runs my own career operations.

A pipeline I designed and built solo that treats my engineering career as a structured database — Git history is the source of truth, and five skill-scoped Claude subagents curate typed records: project history, recruiter-lens framing, company discovery, job matching, and outreach drafting.

Playwright crawlers pull LinkedIn, Wellfound, web3.career, and cryptojobslist against persisted auth. Credentialed writes stay draft-only — agents queue JSON, I press send. 183 repos ingested and four products shipped in the ~10 weeks since I started building it.
