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 — used to ship production-shaped vertical SaaS and interactive products.
  • Shipped Labada, Kintab, BaseShear, Backten, Kolekta, and Resibo for Philippine SME workflows on pnpm + Turborepo, shared design systems, Supabase/Postgres/RLS, PWA behavior, Vitest, and Playwright E2E — Labada and Kintab preparing for founder-assisted local launch.
  • Deepened real-time rendering and performance engineering through browser-game systems R&D (React Three Fiber, Rapier, Zustand, WebGL) across Embervale, Emberkeep, and Conquer Brawl.
AltLayer — Web3 infrastructure startup Sep 2024 – May 2026 · Remote
Senior Software / Product Engineer — Founding FE lead on Rumour & Autonome · MCP platform owner
Architected the pixel/Minecraft design system and React + Vite codebase that ships Rumour as a PWA, Farcaster Miniapp, and LINE DappPortal simultaneously — 1 codebase → 3 platforms — while building and maintaining ~37 protocol MCP servers (~176 tools) for AltLLM's multi-model LLM platform.
  • Rumour (FE lead, rumour.app): designed the pixel/Minecraft component library, token system, and state architecture from scratch under strict design direction (button shadow effects, pixel-grid layouts); integrated Hyperliquid perpetuals, OKX + LI.FI bridging so users choose their bridge provider, Tencent Chat for the social layer, and X/Twitter trend-driven rumour-creation flows — 5+ protocol integrations in one wallet-connected trading UI.
  • 8004scan (8004scan.io): shipped a cross-platform AI-agent explorer as responsive web + installable PWA + Capacitor iOS/Android from one Next.js codebase; SSE-streaming conversational chat with OAuth handoff, a typed API client auto-generated from the OpenAPI spec, and hardened responsiveness across all four shells (iOS auto-zoom prevention, overflow fixes, store download affordances).
  • Autonome + Wizard/RaaS: built agent-configuration UI flows for Autonome from zero; translated Figma wireframes into production UI across Rollup-as-a-Service surfaces; introduced domain-driven design as products converged; built internal admin dashboards for payments, statuses, and rumour review workflows.
  • MCP platform (owner, handed-over): ~37 protocol MCP servers (~176 tools across EVM + Solana) integrated into AltLLM with user-confirmed WRITE operations; built the ManusAI-like chat UI with visible tool calls and OpenRouter multi-model support; dual-model validation harness at ~97% pass.
  • Daily AI-native delivery — Figma MCP to pixel-perfect production, multi-agent orchestration via Claude Code + Codex; E2E coverage with Playwright and Synpress for MetaMask wallet-signing flows.
Limitless Labs — Web3 prediction-markets startup Dec 2023 – Sep 2024 · Remote
Senior Blockchain Engineer — Founding fullstack engineer · Limitless Exchange on Base
Owned the Chakra UI design system, mobile-responsive trading UI, dark-mode rollout, and real-time portfolio calculations; collapsed a multi-step manual market-creation flow to a single operator action.
  • Frontend ownership: built the prediction-markets UI on Chakra UI with Privy wallet auth, subgraph-driven data, Farcaster frames, and a dynamic OG image generator; led the full UI/UX redesign including dark mode and mobile-responsive trading views with real-time portfolio calculations.
  • Market-creation automation: connected FE forms → NestJS REST API → FPMM smart contract → Gnosis Safe multisig into one click, eliminating an error-prone manual operator workflow; backed by an Envio blockchain indexer and Slack/Discord trade-alert bots.
  • Custom FPMM contract iterations (v5, v6) extending the Gnosis Conditional Tokens Framework; MongoDB → PostgreSQL migration with zero data loss; Hardhat + Foundry test coverage for Conditional Tokens and Market Maker contracts.
  • Ran code reviews, planning sessions, and technical specs with product and non-technical stakeholders; founding work helped secure a ~$3M pre-seed led by 1confirmation (Sep 2024).
Atlantis World / Limitless Labs — Web3 metaverse startup Dec 2021 – Dec 2023 · Remote
Lead Blockchain Engineer — Founding engineer, later lead · rebranded to Limitless Labs Dec 2023
Led the full JS → TypeScript migration of the React + Chakra UI + Vite game client; ran the live NFT-sale shift that raised ~$1M ETH (327.14 WETH on Polygon); owned 13 of 18 DeFi protocol integrations end-to-end.
  • JS → TS migration: typed React components, TypeChain bindings, import aliases, and tsconfig across the game client — establishing scalable component patterns and eliminating a class of runtime errors.
  • NFT raise (~$1M ETH): authored the Next.js sale dApp (RainbowKit + wagmi), a Solidity ERC-721 contract built and deployed end-to-end, and a Node.js Merkle allowlist service; Magical Keys ERC-1155 verified on Polygonscan.
  • Owned 13 of 18 protocol integrations end-to-end, shipped as pixel-art in-game NPCs and buildings (Yearn, 1inch, Balancer, Aave, Perpetual Protocol, Moola, Lens, Filecoin, Snapshot, NFT.Storage, POAP, PoolTogether, Swapr); deployed and verified contracts on Ethereum, Polygon, and Optimism.
