Carlo Miguel Dy — Fullstack Engineer

Professional Summary

Senior Fullstack Engineer — 7+ years shipping end-to-end from React/Next.js frontends through Node.js/NestJS/Hono backends to PostgreSQL, with 4+ years in Web3 (DeFi, smart contracts, wallet integrations). Early IC on Rumour, Autonome, Limitless Exchange, and Atlantis World (~$1M ETH NFT raise) — owned implementation from concept to production at each. AI-native daily practice: multi-agent harness engineering and MCP server orchestration against real product workloads (Claude Code + Codex).

Experience

AltLayer Sep 2024 – May 2026 · Remote

Senior Software / Product Engineer — Web3 infrastructure startup (Rollup-as-a-Service + AVS) · FE lead on Rumour & Autonome · MCP platform lead

Shipped full-stack products end-to-end — built and maintained ~37 protocol MCP servers (~176 tools across EVM + Solana) for AltLLM's multi-model LLM platform, migrated Next.js to a stateless Hono API, and delivered React frontends, public REST APIs, and a cross-platform Capacitor app from a single codebase.

FE lead on Rumour (rumour.app) and Autonome (apps.autono.meme); delivered features across Wizard / RaaS, AVS-as-a-Service, 8004scan, AltLLM, and AltClaw with product, backend, and design teams.
MCP platform (lead): built and maintained ~37 protocol MCP servers (~176 tools across EVM + Solana), with user-confirmed WRITE operations and READ-first defaults; migrated Next.js to stateless Hono without breaking the public API; ~97% pass on dual-model LLM validation harness.
Rumour: launched to production as PWA + Farcaster Miniapp + LINE DappPortal from a single React + Vite codebase — Hyperliquid perpetuals, OKX + LI.FI bridging, Privy wallets, Tencent Chat.
8004scan (8004scan.io): shipped live on App Store + Google Play from one Next.js codebase — public REST API (API-key auth, tiered rate-limiting, OpenAPI/Swagger UI) + OAuth + SSE conversational chat.
AI-native delivery: cut Figma-to-production cycle time via Figma MCP; ran agentic security-audit review over AltLLM and AltClaw, reducing manual audit triage to structured epics.

Limitless Labs Dec 2023 – Sep 2024 · Remote

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

Owned four codebases end-to-end (API, contracts, indexer, frontend) — collapsed manual market creation into a single operator action (FE → API → contract → Gnosis Safe), migrated the API datastore MongoDB → PostgreSQL with zero data loss, and helped secure Limitless Labs a $3M pre-seed (1confirmation, Sep 2024).

Full-stack ownership on Limitless Exchange; built FPMM v5 + v6 contracts (extending Gnosis Conditional Tokens Framework); deployed on Base Mainnet + Sepolia.
Backend: NestJS, Fastify, TypeScript, TypeORM, PostgreSQL (domain-driven design); migrated MongoDB → PostgreSQL, zero data loss; multi-chain config (Mainnet / Sepolia / UAT / local).
Automated end-to-end market creation: FE → REST API → smart contract → Gnosis Safe multisig; Envio blockchain indexer; Chakra UI frontend with Privy auth and Farcaster frames.
Stood up Slack/Discord trade-alert bots with CoinGecko USD pricing; comprehensive Hardhat + Foundry test suites required before any on-chain deployment.

Earlier: Freelance Full-Stack Engineer (2019 – 2021) — web/PWA apps, dashboards, custom client systems. · Fligno — Software Engineering / QA Automation Intern — Robot Framework, Appium, Selenium, React Native test automation.
