Protocol & blockchain engineering
Smart-contract integration, indexers, transaction builders, wallets and dApp architecture — the off-chain half most teams underestimate. Available for ecosystems outside Cardano and Midnight.
Services
Hard integrations, delivered end to end
Systems that have to be correct: designing the architecture, building it in TypeScript or Rust, and owning it through to production.
Developer tooling & platform work
VS Code extensions, CLIs and SDKs that a team works in daily, plus the CI/CD, GCP/AWS, Kubernetes and Terraform underneath.
Experience
TxPipe
Blockchain Fullstack Developer
- Metera, architecture to mainnet. Core developer on a Cardano DeFi platform. Designed and owned the entire off-chain integration end to end — transaction building, chain indexing, persistence, API and deployment — working alongside a dedicated on-chain designer, and carried it through to mainnet launch. TypeScript, Lucid, Dolos, UTxORPC, DrizzleORM, PostgreSQL, Next.js, Terraform.
- Tx3 transaction language. Core developer on TxPipe's Tx3 language and a contributor to the Rust Cardano infrastructure underneath it, Pallas and Dolos. Rust, Tokio, Pest, Handlebars.
- Smart-contract audit tooling. Builds the internal VS Code extensions and TypeScript tooling that TxPipe's auditors work in, turning smart-contract review into a repeatable workflow.
- Third-party assurance. Reviews Cardano Vision 2026 milestone deliveries, validating each delivery claim against its stated scope and submitted evidence.
- Midnight dApps and developer education. Designs and builds Midnight dApps and writes TxPipe's educational material on the protocol, turning specification-level concepts into working reference applications.
- Apex Fusion. Built transaction builders for Vector chain stress testing, authored the eUTxO onboarding documentation, and led a proof-of-concept order book on its fast-finality chain.
Earlier
Built and shipped a clothing e-commerce site and an MVP for a Cardano real-estate tokenization platform, front to back. React, Next.js, NestJS, TypeScript, GraphQL, AWS.
Integrated the machine-learning team's MLflow models into a production Django and Google Pub/Sub pipeline, and ran the ElasticSearch, Grafana and Kubernetes infrastructure around it on GCP.
Projects
nico-agent
Open source. A loop where agents implement my GitHub and Linear issues overnight, a second agent on a different harness verifies each PR, and I merge in the morning. Rust, Svelte, herdr.
Metera
Cardano DeFi platform. Designed and owned the complete off-chain integration — transaction building, indexing, persistence, API and infrastructure — and delivered it to mainnet as a core developer.
Tx3
TxPipe's transaction description language. Core developer on the language and its Rust toolchain. Rust, Tokio, Pest, Handlebars, Pallas, Dolos.
Balius Discord Bot, Project Catalyst
Delivered a Project Catalyst milestone on Asteria's Balius Discord bot. Rust, Dolos, Balius, Demeter.
Lace Anatomy
Cardano transaction explorer, built with the Lace Anatomy team. TypeScript, React, Konva, UTxORPC, Cardano DB Sync.
Open source. Secure peer-to-peer .env file management.
Open source. A TUI for managing office LED strips over UNIX sockets.

Questions
What kind of work are you the right person for?
Projects where the engineering is the hard part: protocol and blockchain integrations, systems that have to be correct rather than merely shipped, developer tooling other engineers depend on (like nico-agent, my open-source AI agent orchestrator), and products that need one person to own delivery from architecture through production. I take these end to end rather than joining as an extra pair of hands.
Are you available for freelance or consulting work?
Yes, for select remote-first engagements. For independent blockchain engagements I'm available for ecosystems outside Cardano and Midnight. Reach me by email or on LinkedIn.
How do you work with distributed teams?
Remote-first from Córdoba, Argentina (UTC−3), a working day that overlaps both US and European hours. Native Spanish speaker, fluent in English, working with distributed teams since 2023.
What does your typical stack look like?
TypeScript and Rust are my daily drivers, with hands-on depth across the Cardano stack (Pallas, Dolos, UTxORPC, Lucid, blaze-cardano), plus Next.js, React, NestJS, PostgreSQL, GCP, AWS, Kubernetes and Terraform.
What do you do at TxPipe?
I designed and owned the off-chain integration for Metera through to mainnet, work as a core developer on the Tx3 transaction language, build the internal tooling our smart-contract auditors use, and review Cardano Vision 2026 milestone deliveries against their stated scope and evidence.
How do we start?
Email me a short description of the project, your timeline and a budget range. I usually reply within a day or two with next steps or a short call.
