01Summary

02Experience

Sep 2024 – May 2026 · Remote

Senior Fullstack Engineer AltLayer

  • Led Rumour's frontend from zero to production across PWA, Farcaster Miniapp, and LINE DappPortal from one React/Vite codebase. Scoped features into delivery plans with design, delegated frontend work, and ran weekly demos for the product team, stakeholders, and founders that shaped each release.
  • Built responsive React/MUI social trading, funding, and chat flows from Figma designs, shipping Privy, Hyperliquid, OKX, LI.FI, and Tencent Chat integrations with exponential-backoff retry handling for failed Web3 calls. Led peer code reviews and tested browser and wallet-signing flows with Playwright/Synpress.
  • Architected AltLayer Wizard's migration from a flat React codebase to a modular Domain-Driven Design (DDD) structure, decoupling business logic from UI and eliminating circular dependencies as Rollup-as-a-Service, AVS-as-a-Service, and Autonome converged into one frontend.
  • Built 8004scan's first chat-agent UI with streamed responses and tool calling. Connected remote MCP servers to AltLLM's backend via the Python MCP SDK so agents could execute tools, and helped migrate MCP servers to a stateless Hono API. Maintained cross-product CI/CD with release-please and GitHub Actions.

Dec 2023 – Sep 2024 · Remote

Senior Blockchain Engineer / Founding Engineer Limitless Labs

  • Founding engineer from prototype to production: owned system design and end-to-end delivery across the API, Base smart contracts, indexer, and frontend, growing the product to ~1K DAU. The MVP powered venture-capital demos during Limitless Labs' ~$3M pre-seed raise.
  • Led NestJS/Fastify backend development with domain-driven design (DDD), owning API design, data modelling, PostgreSQL/TypeORM schema design, middleware and security, and API docs; built trading services and wallet-signature JWT authentication and authorization in which users sign to authorize their actions.
  • Owned the Envio onchain indexer end to end: designed entities mapping the market factory contract's emitted events, and handled its deployments, debugging, and integration into the frontend dApp.
  • Built the automated market-creation system on Gnosis's Conditional Tokens and LMSR/FPMM market-maker contracts: multisig-approved Gnosis Safe SDK batch transactions prepare the condition, approve token spend, create the market, and provision liquidity atomically, with onchain outcome reporting at resolution.
  • Owned end-to-end smart-contract tests for the full prediction-market lifecycle (market creation, funding, share trading, outcome reporting, and reward claims) with Hardhat, Mocha, Chai, and viem; shipped GitHub Actions releases across four codebases.

Dec 2021 – Dec 2023 · Remote

Blockchain Engineer → Lead Blockchain Engineer Atlantis World

  • Promoted to Lead Blockchain Engineer after the sale launch; led a 4-engineer Web3 pod delivering grant-funded partner protocol integrations, decomposing and delegating work, and coordinating asynchronously with the US-based Game pod and cross-functional teams across US/EU time zones.
  • Owned partner DeFi/Web3 protocol integrations into the metaverse, surfaced in-game through NPCs; delivered 13 of 18 end to end and oversaw the remaining five with the team.
  • Built the Next.js sale dApp with MetaMask/RainbowKit wallet auth and a Node.js Merkle allowlist service, supporting a ~$1M community raise settled as 327.14 WETH on Polygon; rigorously tested the end-to-end sale flow on testnet and iterated on the UI/UX.
  • For the NFT sale contract, which a colleague owned, Carlo owned writing its unit and E2E test suites, deployed it to Polygon Mumbai Testnet and Ethereum Sepolia Testnet, ran smoke tests to confirm its production readiness, and handled its Polygon Mainnet deployment for the launch. Carlo made minimal refactors to the smart contracts.
  • Led the React/Vite game client's migration from JavaScript to TypeScript and set its engineering standards: domain-driven frontend architecture, typed components and TypeChain bindings, linting with Prettier and ESLint, Husky pre-commit hooks, unit and E2E tests, and GitHub Actions CI.

Apr 2021 – Feb 2022 · Remote

Software Engineer FilledStacks

  • Built Flutter/Firebase client apps end to end from Figma designs with the Stacked framework, decoupling UI from business logic for testable, maintainable code, and data-modelled core Firestore entities; shipped through sprint cycles with client demos and retrospectives.
  • Contributed to FilledStacks' open-source Flutter packages, published on pub.dev for the wider Flutter developer community.
  • Authored technical specs for assigned features, refined through peer review to Team Lead approval alongside design and stakeholders.
  • Pair-programmed with a principal engineer to port a football tournament engine (match generation and scoring) from Python to TypeScript for Firebase Cloud Functions, which lacked Python support at the time.
  • Applied test-driven development (TDD) to business logic; authored multi-tenant prebuild scripts so multiple client apps shipped from one codebase to separate Firebase projects, and maintained Codemagic CI/CD.

Aug 2020 – Jan 2022 · Philippines / Remote

Lead Software Engineer Infina, Ltd.

  • Led a 3-engineer remote team delivering an Angular/Ionic workforce analytics application for government agencies; provided technical guidance, mentored junior engineers, conducted code reviews, and drove refactoring to maintain code quality as the product grew.
  • Built interactive workforce dashboards and optimized SQL queries over large datasets to improve dashboard load times; collaborated with the Designer and Data Analyst on application delivery.
  • Deployed and maintained Nginx/AWS EC2 environments across development, staging, and production; managed environment-specific configuration and deployment workflows, coordinating with the Project Manager and DevOps Engineer across time zones.

Jan 2020 – Apr 2020 · Philippines

Software Engineering Intern / QA Automation Intern Fligno

  • Wrote automated web application tests with Robot Framework and mobile automation tests for React Native apps with Appium (Python) and Selenium, working alongside QA and software engineers.

2019 – 2020

Freelance Full-Stack Engineer Client projects

  • Delivered childcare management systems, floor-plan visual CRM tools, and a startup tracking application for a government technology incubator; worked directly with clients to clarify requirements and propose solutions.
  • Designed frontend/backend architecture, REST APIs, and database models; applied TDD and scripted AWS EC2/GCP deployments, supporting maintenance, bug fixes, and product iteration after delivery.
