About
Slow roots, fast growth.
I’m Carlo — a senior product engineer from the Philippines who has spent seven-plus years learning that good software grows from real soil, with patient tending, pruned honestly.
My roots are in full-stack product work — childcare systems, government dashboards, Flutter apps at a consultancy, a three-engineer team I led at Infina. Then in 2021 I moved into Web3: founding engineer at Atlantis World, where DeFi protocols became pixel-art NPCs and a community NFT sale I ran live moved 327.14 WETH — roughly $1M at the time — on-chain. From there, founding fullstack engineer at Limitless Exchange, then AltLayer, where I built Rumour and Autonome from zero and inherited an MCP server platform that I grew into the protocol layer of an LLM product.
The AI-native part isn’t a trend I’m chasing — it’s how I work daily. Claude Code, Codex, and Cursor sit in my toolbox next to Playwright and Foundry. I design agent harnesses, review their output like a lead reviews a team, and hold everything to the same bar: evidence before “done.”
Currently seeking a senior IC seat on a team that ships — and running an independent product studio in the meantime.

How I work
Tending, not just planting.
Evidence before “done.”
Nothing ships on a feeling. Unit tests, Playwright E2E, Synpress wallet flows, manual QA — a feature is finished when the proof exists, not when the code compiles.
Own the whole stem.
From vague requirement to production and beyond: break the problem down, design the system, implement, test, debug, ship, then keep tending it. Inherited codebases count double — ownership beats greenfield.
Prune honestly.
Small, focused modules; domain-driven boundaries; refactors done when they're needed, not when they're glamorous. A codebase should read like a well-kept bed, not an overgrown lot.
Tend daily with AI.
Agent harnesses, multi-agent orchestration, and provider-aware workflows are my daily practice — and their output is reviewed like a lead reviews a team, held to the same evidence bar as my own.

Kind words
What the grove says.
From engineers, designers, and leads I’ve shared a season with — quoted as written.
What stands out most is his ability to translate ambiguous product requirements into reliable, maintainable software. He works comfortably across product, design, and engineering, moves quickly when prototyping, and strengthens delivery through thoughtful architecture, comprehensive testing, and hands-on production support. His range across full-stack engineering, blockchain systems, and agentic AI makes him a versatile and dependable contributor in fast-moving product environments.
Jun Hao Tan
Head of Product Engineering · AltLayer
Carlo is an exceptionally talented engineer with a very unique full-stack profile in crypto. He can work on all ends of the crypto stack. I've personally worked with him on Developer DAO projects in the early days and couldn't recommend him more!
Dhaiwat
Engineer · ENS Domains
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.
Cong Yang
Frontend Engineer · AltLayer
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.
Fu Xiao
Product UI/UX Designer · AltLayer
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.
Henry Kim
DevOps Engineer · AltLayer
Working across the full stack—from dApps frontend to onchain protocol architecture, cloud infrastructure, and backend—Carlo was the definition of a team-first engineer. In a high-velocity startup environment he stayed constantly in sync, brought best practices that raised the team's level, and got his hands dirty on every kind of tech challenge. A true builder, a true engineer—and the kind of person who makes the whole team better.
Max Surhai
Principal Software Engineer · Limitless Labs
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.
James Darrel
Junior Software Engineer & Workflow Automation Specialist · Independent
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.
Riel Joseph Bulaybulay
Senior Backend & Blockchain Engineer · Independent
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.
