Built to
burn
problems
down.

I build money infrastructure — lending, payments, products real companies acquire. Not because it’s a job. Because good enough is not enough.

I don't just write code. I develop a deep obsession with the domain until I understand it better than almost anyone in the room.

I started writing code at 17 — not because someone handed me a curriculum, but because broken systems bothered me more than broken grades. At MetaKeep, within my first year on the job, I shipped an acquisition-grade payment integration that became the technical backbone of due diligence for a NASDAQ-listed deal. At Revalon, I built the core lending engine from scratch — pricing risk, executing loans, running it live with zero bad debt

Before this, I worked alongside engineers who built WhatsApp Pay, Meta’s Diem, and Twitter’s social graph. That’s the bar I hold myself to: not whether something works, but whether it’s right

The edge

01

Domain Obsession

I don't ship features — I internalize the problem space. Lending platforms, payment systems, account security — I go deep until I understand the threat model, the incentive structure, the edge cases that kill companies. Then I build.

02

Zero-to-Production Speed

From zero to a payment onboarding flow used in a NASDAQ acquisition. From zero to a lending platform with disciplined automated execution and integrated risk controls. Most engineers prototype. I ship.

03

System-Level Thinking

I see the whole board — core platform, application layer, DevOps, security architecture. When I build lending infrastructure I think about recovery workflows, custody boundaries, reconciliation, and auditable decision trails simultaneously.

The record

Revalon Finance

Remote · Platform Engineering · Financial Infrastructure

  • Shipped to Polygon Amoy testnet — 22 on-chain loans, $3,360 USDC borrowed, 100% repayment rate across 21 beta wallets, 21 invite redemptions; live analytics dashboard, every metric verifiable on Polygonscan.
  • Architected a production-grade floor-aware lending protocol on Polygon — 5 Solidity contracts, 7-guard on-chain quote verification, 48h TimelockController, and 3-of-5 Gnosis Safe multisig — zero bad debt across full testnet lifecycle.
  • Built a real-time LTV engine in Go — 7 market signals drive dynamic LTV (50–80% floor), with automated 3-tier margin calls and full audit trails for every collateral health change.
  • Shipped Polymarket collateral end-to-end (ERC-1155 vault custody, signed floor snapshots); built Kalshi backend (CFTC API attestation, KMS-encrypted read-only keys, 60s health polling).
  • Designed 7-layer security (AWS KMS, CEI, flash-loan resistance, Redis rate limiting — rejected 99.96% of ~4,500 req/s abuse burst); deployed on DO App Platform at $24/mo with GitHub Actions CD, p95 <20ms under load.
  • Built borrower-facing UI in Next.js — portfolio dashboard, quote-to-borrow flow with Privy, SSE-driven loan updates (~50–100ms post-confirmation), IndexedDB recovery, and invite-gated beta with HMAC JWT auth.

MetaKeep (Acquired)

Rezolve AI · NASDAQ: RZLV · Remote

  • Engineered the end-to-end payment integration that served as the primary technical validator for MetaKeep's acquisition by Rezolve AI (NASDAQ: RZLV), March 2026 — built on Reown Wallet Mobile Kit and MetaKeep SDK, enabling sign-up-free transactions inside a chatbot UI for luxury retail.
  • Led Wallet Isolation — an enterprise security feature requested by Solana, enforcing per-app key segregation across a wallet infrastructure platform managing 10M+ wallets; reduced pre-production bugs by 40%.
  • Built MetaKeep's crypto onramp from zero to production in TypeScript — integrated Coinbase API and MetaKeep SDK for zero-fee, sign-up-free purchases; architected a MoonPay fiat-to-token rail chaining card purchases through Jupiter swaps with auto-deposit into MetaKeep wallets.
  • Designed an on-chain USDC transfer system using SPL token delegation, eliminating repeated approval flows and reducing transaction friction for end users.
  • Shipped 8 SDK integration demos (6 Android, 2 iOS) covering Solana and Ethereum transaction flows — used as developer documentation and sales tooling for enterprise partners.

The room I was in

“Being in a room with people who've shipped systems at civilisational scale doesn't just teach you — it permanently recalibrates what you think is possible.”
