Experience

Independent AI-Native Product Studio May 2026 – Present · Remote

Independent AI-Native Product Engineer / Technical Founder

Built saas-launch, a provider-aware production system with phase gates, persistent handoffs, independent review, and evidence-backed verification, with Labada and Kintab preparing for local launch.

Standardized delivery around pnpm + Turborepo, shared schemas, Supabase/Postgres/RLS, unit tests, Playwright E2E, and CI/CD across the studio's product line.

AltLayer Sep 2024 – May 2026 · Remote

Senior Software / Product Engineer — Founding FE on Rumour & Autonome · MCP platform owner

Built and maintained ~37 protocol MCP servers (~176 tools across EVM + Solana) integrated into AltLLM's multi-model LLM platform; achieved a ~97% dual-model validation pass-rate; shipped agentic security-audit review over AltLLM and AltClaw.

MCP platform (owner): built and maintained ~37 protocol MCP servers across Spark, EigenLayer, 1inch, OKX, LI.FI, OpenSea, Kalshi, DefiLlama, and more — migrated Next.js to a stateless Hono API; each server kept focused per protocol (swap, staking, lending, DEX, wallet, bridge, prediction) with READ-first defaults and guided schema-level tool-calling examples for reliable selection.
Agentic security-audit review: via Claude Code + Codex over AltLLM / AltClaw: findings converted to epics, incrementally fixed with automated + manual verification on Docker Compose stacks.
Rumour (FE lead): pixel/Minecraft-style UI from one React + Vite codebase as PWA, Farcaster Miniapp, and LINE DappPortal; Hyperliquid perpetuals; OKX + LI.FI bridging.

Limitless Labs Dec 2023 – Sep 2024 · Remote

Senior Blockchain Engineer — Founding fullstack engineer · Limitless Exchange prediction markets on Base

Authored custom FPMM v5 & v6 contracts extending Gnosis Protocol's Fixed Product Market Maker with modified storage layout and fee logic; collapsed manual market creation into a single operator action; founding-engineering work helped secure a $3M pre-seed led by 1confirmation (Sep 2024).

Owned all four codebases — smart contracts, API, indexer, and frontend — on Limitless Exchange from day one; wrote deploy scripts for Base Mainnet, Base Sepolia, Blast Sepolia, and local environments.
Solidity depth: built custom FPMM contract iterations (v5, v6) extending Gnosis Protocol's Fixed Product Market Maker; deliberate storage-layout versioning (v5 → v6); modified fee logic and market-maker risk handling; LMSR market maker integration with WETH9 collateral.
Contract testing: comprehensive Hardhat + Foundry test suites for the Conditional Tokens Framework and both FPMM versions; mock ERC-20 collateral token infrastructure; multi-chain deployment scripts across Base, Blast Sepolia, and Base Sepolia.
Automated end-to-end market creation — FE → REST API → smart contract → Gnosis Safe multisig — collapsing a multi-step manual operator workflow into one action; migrated the datastore from MongoDB to PostgreSQL with zero data loss.
