I
I work independently on Web3, AI, and early-stage product projects, contributing across product strategy, user flows, documentation, storytelling, community coordination, and prototype development.
I have participated in several hackathons and builder programs, including Chainlink, ETH Bogotá, Protocol Labs, Encode x Polkadot, Colsubsidio x 30X, and others, working on projects related to climate tech, ReFi, AI operations, blockchain infrastructure, and digital innovation.

What Problem Are We Solving? In the Real-World Assets (RWA) space, the gap between off-chain data and on-chain representations remains a critical barrier to mass adoption. Key technical challenges include: Data Fragmentation & Integrity Risks Multiple, siloed data sources (market APIs, centralized databases, manual records) lead to inconsistent or stale asset valuations. Lack of cryptographic validation invites discrepancies and potential manipulation. High Operational Overhead Manual or semi-automated data verification pipelines incur latency and cost, limiting throughput for tokenized assets. Complex orchestration of disparate services increases failure surface and maintenance burden. Limited Multichain Interoperability Single-chain deployments constrain liquidity and composability. Non-native bridging solutions introduce custodial and gas inefficiencies. Our Solution: RWA MultiChain Infrastructure We present a fully automated, end-to-end framework that addresses these pain points through: AI-Driven Oracles (Eliza + Chainlink Functions) Autonomous agents collect, normalize and cryptographically attest real-world data (market prices, ESG metrics, regulatory feeds) before injecting it on-chain, ensuring integrity and auditability. Chainlink Automation as Cron-Engine On-chain scheduling of periodic data fetches and validations eliminates manual intervention, slashes operational costs, and maintains up-to-date asset state. Native Multichain Bridges with Chainlink CCIP Leveraging CCIP on enabled networks, we build secure, non-custodial bridges that seamlessly transfer RWA tokens across chains, unlocking global liquidity pools. Impact & Competitive Advantages Deterministic Transparency All data ingestions and oracle attestations are recorded immutably, enabling real-time, verifiable audit trails for stakeholders. Operational Scalability Fully on-chain automation compresses weeks of manual work into milliseconds, supporting high-frequency updates without human bottlenecks. Plug-and-Play Architecture Modular components allow rapid onboarding of new asset classes (real estate, commodities, debt instruments) and data feeds. Decentralized Trust Model By decentralizing oracle computation and bridging logic, we remove single points of failure and align with Web3 security best practices. With RWA MultiChain Infrastructure, we’re not just delivering an MVP—we’re laying the foundation for a new era where physical assets, decentralized protocols, and intelligent automation converge to create dynamic, borderless financial systems.

A project from Cali, Colombia, and a reminder that technology works best when it helps people face real problems. I built MINGA Grid around a practical idea: when the electricity grid is under pressure, the people who can reduce their consumption should have a clear way to participate and be rewarded. In Colombia, the evening peak is one of those moments. Demand rises, electricity becomes more expensive, and the grid has less flexibility. A business that can safely use less energy for a few hours can he...

How i built ZERO, a prevention-finance protocol that turns verified prevention into a fundable, auditable and payable outcome ZERO — Prevention is an outcome. This project and this article were created for the purpose of entering the H01 Hackathon. #H01Hackathon Our world knows how to pay after a tragedy. It still does not know how to fund one that never happens. When a community floods, a disease spreads or critical infrastructure fails, money moves. Governments declare emergencies. Insurers calculate l...

“In 1988, a group of economists at the University of Iowa built a market where people could bet real money on the outcome of U.S. presidential elections. Over the next 15 years, that market outperformed professional pollsters in accuracy — consistently, repeatedly, embarrassingly.” Not because participants were smarter than the experts. But because when people put real money behind a prediction, they stop lying. That insight — that financial skin in the game produces honest signals — is the foundation of...
