About
Senior fullstack engineer — 7+ years software, 4+ years specializing in Web3. Based in Northern Mindanao, Philippines, working remote-IC. The last few years split between Web3 product builds (DeFi, wallets, social trading, prediction markets, NFT launches, indexer-backed orchestration) and AI-augmented systems (MCP server design, router orchestration over large tool sets, function-calling, human-in-the-loop approval flows).
Former founding frontend engineer of Rumour and Autonome — AltLayer products I built from zero. Former founding engineer (fullstack) of Limitless Exchange at Limitless Labs. Founding engineer at Atlantis World, where the community NFT raise moved roughly $1M in ETH. Looking back at four end-to-end builds where I owned product engineering before knowing it had a name — taking ambiguous requirements from concept to ship, frontend to smart contract to operational glue.
Daily AI-augmented engineering practice — harness engineering, context engineering, multi-agent orchestration, agent teams. Started at AltLayer building MCP harnesses and multi-agent flows; now a daily loop where I tune action spaces, tool surfaces, and guardrails so autonomous agent teams produce high-quality outputs end-to-end. Claude Code, Codex, and Multica AI are where I work, not tools I reach for.
Primary focus is finding a new team. Open to senior software, senior frontend, senior blockchain, senior fullstack, and senior product engineer roles — IC, on a team.

Founding engineer · community NFT raise (≈$1M ETH)
Promoted from blockchain engineer to lead blockchain engineer on an early-stage 2D pixel-art Web3 social metaverse — players walked a shared world and stepped into in-game buildings wrapping real DeFi protocols. Built the game client on React, Chakra UI, and Vite, and led a full JavaScript-to-TypeScript migration. Ran the live shift for the community NFT sale that raised approximately $1M in ETH. Owned 13 of the 18 DeFi/Web3 protocol integrations end-to-end — Yearn Finance, 1inch, Balancer, Aave, Perpetual Protocol, Moola, Lens Protocol, Filecoin, Snapshot, NFT.Storage, POAP, PoolTogether, and Swapr — and contributed to and oversaw the remaining 5 alongside the team (Trader Joe, mStable, Float Capital, dYdX, ENS).

What people say
Carlo is an exceptional engineer with a deep understanding of the Web3 ecosystem. He has a knack for translating complex product logic into seamless user experiences. Beyond his technical prowess, he is a highly collaborative teammate who makes cross-functional communication effortless.
Carlo possesses an exceptional aesthetic sensibility combined with a holistic technical vision. With Carlo as a partner, the ‘expectation gap’ between design and the final product simply doesn’t exist. Whether crafting nuanced frontend interactions or architecting robust backend logic, he handles the entire stack with mastery.
Carlo communicates clearly, asks thoughtful questions, and is always willing to jump in to debug issues or adapt when project requirements change. I appreciated his ownership mindset, especially across backend, API, and infrastructure-related tasks. He follows through, learns quickly, and brings a positive attitude to the team.
I was lucky enough to work together with Carlo on multiple projects in different roles. Starting from dApps frontend and down to on-chain protocols architecture, cloud and backend infrastructure. It worth to say, for a long time we've been working in a highly strartup-ed environment: fast market, enormous competitiveness, high level of uncertainty, tech challenges etc. And I'd like to express a huge respect and gratitude to Carlo for his team playing, engineering and startup skills! The man was constantly in sync, never missed a meet, managed all the tickets, often brought best practices to push team level forward, over-timed, constantly learned new tools and approaches on the market, got his hands dirty in all kinds of tech challenges, and, more important, was a true team player supporting his teammates technically and emotionally! Learned a lot from you, Carlo! Thanks for all your effort and sleepless nights, you're a true builder, a true engineer and a great person! Please, keep making this world a better place! Peace!
Carlo has a rare ability to break down complex technical hurdles into digestible steps—making even the hardest concepts feel approachable. The logic and problem-solving foundation he gave me has provided a significant edge in my career long after our work together. Any team looking for a mentor would be lucky to have him.
Carlo takes full ownership of his work and genuinely cares about quality. He communicates clearly, never needs micromanaging, and stays calm under pressure when timelines get tight—which is exactly when it matters most. Working with him always felt smooth and productive, and I'd recommend him to any team without hesitation.
Carlo was a pleasure to work with during our 2 years together at AltLayer. Remote collaboration can be difficult, but Carlo maintained a consistently reliable online presence throughout. I appreciate the full-stack contributions he made and would recommend him to anyone in need of those services.
