Carlo Miguel Dy — Senior Fullstack Engineer

Professional Summary

Senior Fullstack Engineer — 7+ years software, 4+ years Web3 — who ships products end-to-end: React/Next.js frontends, NestJS/Hono backends, PostgreSQL data layers, smart contracts, and CI/CD delivery to production. Built Rumour (social trading, rumour.app) and Limitless Exchange (prediction markets on Base) from zero as founding frontend/fullstack engineer; founding work on Limitless helped secure a ~$3M pre-seed led by 1confirmation. Built and maintained ~37 protocol MCP servers (~176 tools across EVM + Solana) integrated into AltLLM's multi-model LLM platform. Daily AI-native practice with Claude Code, Codex, and multi-agent orchestration against real product workloads.

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 end-to-end.

Shipped Labada, Kintab, BaseShear, Backten, Kolekta, and Resibo for Philippine SME workflows — full stacks on pnpm + Turborepo, Supabase/Postgres/RLS, PWA behavior, Vitest, Playwright E2E, CI, and deployment; Labada and Kintab preparing for founder-assisted local launch.
Built four cumulative agent-harness tiers, from minimal repository rules through structured multi-agent delivery, with Codex as the primary production environment.

AltLayer Sep 2024 – May 2026 · Remote

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

Owned frontend-to-backend delivery across six product surfaces — built and maintained ~37 protocol MCP servers (~176 tools across EVM + Solana), migrated the platform from Next.js to a stateless Hono API, and shipped a public developer API with tiered rate limiting and hosted Swagger UI.

MCP platform (owner, backend): ~37 protocol MCP servers integrated into AltLLM's multi-model LLM platform with user-confirmed WRITE operations, covering swap, staking, lending, DEX, wallet, bridge, and prediction-market integrations (Spark, EigenLayer, 1inch, OKX, LI.FI, OpenSea, Kalshi, DefiLlama); one focused server per protocol with guided schemas and READ-first defaults; migrated stateful Next.js → stateless Hono API with no public-API breakage; dual-model LLM validation harness reached ~97% pass across ~37 protocols / ~176 tools.
Rumour (FE lead, rumour.app): shipped from a single React + Vite codebase as a PWA, Farcaster Miniapp, and LINE DappPortal — three distribution channels with one build; integrated Hyperliquid perpetuals, OKX + LI.FI cross-chain bridging, and Tencent Chat for the social layer.
8004scan (fullstack, 8004scan.io): cross-platform ERC-8004 agent explorer — responsive web, PWA, and Capacitor iOS/Android; conversational chat with OAuth handoff + SSE streaming; public developer API with key auth, tiered rate limiting, OpenAPI spec, and hosted Swagger UI; typed API client generated from the spec keeps the FE/BE contract enforced at compile time.
Architecture + delivery: introduced domain-driven design across Wizard / Rollup-as-a-Service, adopted by subsequent surfaces; assumed full MCP platform ownership when backend engineers were redeployed; shipped Autonome, AltLLM, and AltClaw features alongside the full product team, with Playwright + Synpress E2E coverage.

Limitless Labs Dec 2023 – Sep 2024 · Remote

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

Owned all four codebases — API, smart contracts, indexer, frontend — with DDD on NestJS/Fastify/PostgreSQL; MongoDB → PostgreSQL migration with zero data loss; manual market creation collapsed to a single operator action.

Backend architecture: NestJS, Fastify, TypeScript, Prisma/TypeORM, PostgreSQL with domain-driven design; one codebase safely targeting Base Mainnet / Sepolia / UAT / local via chain-specific configuration.
End-to-end automation: reduced a manual, error-prone market-creation workflow spanning FE, API, smart contract, and Gnosis Safe multisig approval to one operator click — eliminating a class of operational errors entirely.
Built custom FPMM contracts (v5, v6) extending the Gnosis Conditional Tokens Framework; Envio blockchain indexer; Slack/Discord trade-alert bots with CoinGecko USD pricing; Hardhat + Foundry test coverage.
Frontend on Chakra UI with Privy wallet auth and Farcaster frames; led the full UI/UX redesign with dark mode and real-time portfolio calculations; founding work helped secure the ~$3M pre-seed (1confirmation, Sep 2024).

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 for the live NFT sale; Magical Keys ERC-1155 verified on Polygonscan.
Owned 13 of 18 protocol integrations end-to-end (Yearn, 1inch, Balancer, Aave, Perpetual Protocol, Moola, Lens, Filecoin, Snapshot, NFT.Storage, POAP, PoolTogether, Swapr) and oversaw 5 more; built Web3 auth — MetaMask via Ethers + TypeChain, Discord OAuth, Socket.IO game-server auth.
Led the JavaScript-to-TypeScript migration of the React + Chakra UI + Vite game client; set up the IPFS asset pipeline, Docker, and GitHub Actions CI/CD; deployed and verified contracts across Ethereum, Polygon, and Optimism.
