The Rundown

5+ years shipping across industries and borders. Most of what I built is still in production.

~/about — profile.tsx

I care about the details most people never see — the loading state that feels right, the API response that's 200ms faster, the code a teammate reads six months later and actually understands. I've shipped products in Brazil, Canada, and remotely for international teams. I build things that matter, not just things that work.

Professional Experience

Senior Full Stack Engineer

Frequency Advisors

via Meta IT2025 - Present

Helped build a blockchain-verified ad marketplace on Berachain — advertisers pay only for verified on-chain conversions, not clicks or impressions, attacking the structural fraud built into traditional ad networks. Saw it through from prototype to mainnet launch (Feb 2026) and into a Shopify-native affiliate attribution pivot
Shipped React, Next.js and TypeScript across the stack — campaign dashboards, publisher onboarding, real-time creator earnings, and an AI-assisted campaign briefing assistant built on the Anthropic API. Auth0 for sign-in, ThirdWeb for invisible wallet creation — users get blockchain verification without ever seeing the chain
Built Node.js / NestJS services that dispatch signed transactions to smart contracts on Berachain (via ThirdWeb and Alchemy), mirror on-chain state through a Goldsky subgraph indexer, and route commissions through a Stripe escrow flow — 30-day holds, automatic refund clawbacks, direct bank payouts
Fully remote from Brazil with a UK/US team — engineering, design, and BD on a fully on-chain product launching to mainnet on a fixed date

5G Telecom Digital Platform

Paradise Mobile is Bermuda's first cloud-native 5G operator — and I helped build everything they needed on the software side. Customer onboarding, back-office automation, CRM integrations, internal tooling. If it wasn't the radio network itself, my team probably shipped it.
