Professional Summary

Senior engineer with deep experience across backend systems, product engineering, Rust, TypeScript, AI-powered products, and Solana since 2021. I build technically strong systems that are also usable in the real world, from on-chain programs and crypto products to full-stack applications and internal tooling. Strongest in backend architecture, protocol and smart contract logic, and turning ambiguous ideas into shipped products.

Core Skills

  • Solana, Rust, Anchor, smart contracts, on-chain program design
  • Backend architecture, API design, distributed systems, PostgreSQL, Prisma
  • TypeScript, React, Next.js, Node.js, Vite
  • AI-native product design, agent workflows, LLM integrations, moderation systems
  • Product thinking, startup execution, technical leadership, rapid prototyping

Experience

Dare Market — Senior Engineer / Product Engineer

Current · Remote

Web3-powered challenge marketplace on Solana where users create, fund, participate in, and win crypto-backed dares.

  • Played an important role across product, architecture, and the Solana program side.
  • Worked across the core product stack spanning Solana contracts, the main Next.js application, and backend workflows.
  • Contributed to contract-side design and implementation for a real-money, user-facing product built on Solana.
  • Helped shape a system that combines on-chain game/challenge mechanics with off-chain product, moderation, and payout flows.
  • Worked in a stack including Solana, Rust/Anchor, TypeScript, Next.js, PostgreSQL, Prisma, Privy, and AI moderation services.

Mootrack — Co-founder / Lead Engineer

Current · LATAM / Colombia

Solana-powered cattle traceability and farm management platform for ranchers in LATAM, evolving into an AI-native operating system for livestock farms.

  • Leading the product and technical direction for a platform that combines farm software, AI, and on-chain animal identity.
  • Built the technical foundation for digitizing livestock records, operations, and traceability in a real-world industry with poor software penetration.
  • Worked on the product vision for using Solana as infrastructure for verifiable animal identity, traceability, ownership history, and future financing rails.
  • Helped secure pilot farms and shaped the MVP around real operational ranch workflows instead of speculative crypto use cases.
  • Driving the AI assistant direction for Mootrack, focused on personalized farm copilots and tool-based operational workflows.

BAXUS — Senior Engineer

Remote

Consumer crypto product with real users and strong brand recognition in the Solana ecosystem.

  • Built product and engineering systems in a live crypto environment with real customer-facing impact.
  • Worked across backend, product, and blockchain-facing functionality rather than staying boxed into a single layer.
  • Contributed to shipping polished user experiences on top of technically complex crypto infrastructure.

PrintXD / Print World — Senior Rust Engineer

Remote

  • Worked as a senior Rust engineer on production systems.
  • Focused on backend and systems-level engineering with strong ownership over implementation quality.
  • Strengthened expertise in Rust as part of a broader systems and product engineering toolkit.

10Pearls — Senior / Lead Full-Stack Engineer

Remote

  • Built and shipped client-facing software products across backend and frontend layers.
  • Worked closely with product direction, delivery, and implementation in startup-style environments.
  • Developed strong range across architecture, execution, and shipping under real-world constraints.

Selected Projects

PushFlip

Crypto-native push-your-luck card game on Solana with token mechanics, AI opponent flows, and ZK-based deck verification.

  • Designed to showcase advanced Solana engineering, on-chain game logic, and provable fairness patterns.
  • Combines Rust, Solana programs, backend services, and zero-knowledge infrastructure.

SOLClaw

Agent runtime and protocol concept for putting AI agents on-chain on Solana.

  • Explored agent identity, memory anchoring, task execution, and payment rails as protocol primitives.
  • Combined product thinking with Solana-native systems design and AI infrastructure ideas.

Solana / Web3 Highlights

  • Building on Solana since 2021.
  • Production experience with Solana programs, crypto products, and wallet-connected applications.
  • Experience spanning smart contracts, backend systems, consumer product engineering, and AI-native crypto applications.
  • Strong preference for blockchain used as infrastructure for real products, not just speculation.

Hackathons / Ecosystem

  • Participated in Solana ecosystem hackathons and startup programs.
  • Breakout / Colosseum-related participation.
  • Active builder around Solana, AI, and product experimentation.

Education / Additional

  • Languages: English, Spanish
  • Based in Medellín, Colombia
