Full Stack Web3 Dev (Ph D Fulbright)

I’m a full-stack Web3 engineer experienced in DeFi vaults, account abstraction, and cross-chain governance.

I currently lead development for OP Venture Studio at WakeUp Labs, building DAMM Capital’s infrastructure on Optimism. Integrated Lagoon Vaults (ERC-4626/7540), automated market-making and dynamic rebalancing systems, and account abstraction (EIP-4337) via Privy and Safe. I developed the backend architecture (Python/FastAPI, Postgres, Redis, custom indexers, keeper bots) and delivered a production-ready multi-chain, AA-enabled DeFi platform. Developed the front-end on Next.js + TypeScript UI + react tanstack.

Previously, I created the Libélula encrypted vault protocol, using IPFS/Filecoin, ERC-1155 permissioning, EIP-712 signatures, NestJS, Supabase, and cross-chain access validation. Before, I led and launched Proof of Humanity v2 development at Kleros, building cross-chain governance via Snapshot + SafeSnap, smart contracts, subgraphs, and frontends, and conducting research on neuro-symbolic AI for dispute resolution.

Before Web3, I spent +12 years in neuro-symbolic AI and formal reasoning in legal systems (PhD CS, Fulbright @Pittsburgh, MSc legal reasoning, BA+MSc CS).

I’m seeking senior engineering roles in DeFi, AA, cross-chain infra, or high-impact protocol development. R&D on decentralized automatic reasoning is also of interest.

Experience

full-stack web3 dev
WakeUp Labs
2025 - 2025
I serve as the lead developer of OP Venture Studio at WakeUp Labs: a joint initiative by WakeUp Labs and the Optimism Collective aimed at accelerating high-impact dApps across the Superchain. I lead the end-to-end development of DAMM Capital’s DeFi infrastructure on Optimism, integrating Lagoon Vaults (ERCs 4626 and 7540), and DAMM’s automated market-making systems and dynamic rebalancing mechanisms. To ensure seamless user interaction, I implemented an account abstraction (EIP-4337) solution integrating Privy wallets, after developing and comparing integrations of Thirdweb’s, Coinbase’s CDP and Safe’s solutions for EIP-4337. On the backend, I designed and implemented Python services using FastAPI, PostgreSQL, and Redis as a message broker for WebSocket updates. Developed a custom indexer for event tracking and a keeper bot to automate Safe-based vault operations. Deployed services via Docker with CI/CD integration. The project is now entering its final stage before production, with upcoming expansion towards multi-chain liquidity coordination. See staging. In addition, I designed and developed a DeFi vault platform mini-app for the worldapp in Worldchain. I assisted to DevConnect Buenos Aires and was invited as key-speaker to present my research on onchain legal proofs assisted with AI machinery for traceable and replayable legal reasoning.

Libelula Space
2024 - 2025
Early 2025, I designed and developed Libélula Space, a decentralized encrypted content vault protocol with cross-chain access control. A Web3 platform for secure, token-gated content sharing using IPFS, ERC-1155 access tokens, and EIP-712 signature-based permissions. I architected the system using Next.js for the front-end, The Graph protocol for subgraphs, NestJS and Supabase on the back-end, and Solidity smart-contracts. Implemented per-user end-to-end encryption with dynamic key derivation and vault-level permissioning. Cross-chain access validation through arbitrary message bridge, allowing DAOs to gate content based on multichain token balances granting voting powers on snapshot proposals (integrated via proposal id)
full-stack developer
Kleros - Proof of Humanity
2023 - 2024
Developed and launched Proof of Humanity v2, a decentralized sybil-resistant registry of humans. Full-stack accross Nextjs front-end, The Graph protocol subgraphs, Solidity smart contracts (including cross-chain features), and Nestjs backend developing keeper-bots. DAO configuration to facilitate cross-chain governance-related tasks, like configuring voting proposals and triggering encoded txs from a Snapshot space on mainnet to be bridged automatically throughout Gnosis Safe accounts via Safesnap modules into foreign chains to govern deployed contracts. Pure backend side cron jobs and bots dev under Nestjs. At Kleros I also studied the integration of AI into Kleros' dispute resolution protocol and supervised postgraduate students applying legal theories to the Kleros protocol. In 2024, I assisted to EthCC (Brussels) and DevCon (Bangkok), further expanding my knowledge on blockchain technologies and taking advantage of the opportunity to discuss my research on neuro-symbolic AI applied to dispute resolution on blockchain.
Full-stack developer
Quasar Legal
2020 - 2023
Led a small dev team developing an ERP system for legal case management. Fullstack dev React + Python.
Full-stack developer
Legal Doctor
2018 - 2019
Designed and developed backoffice and data management software for law firm assistance.
Fulbright post-doc
University of Pittsburgh, PA – Hofstra University, NY
2017 - 2017
In 2017 I was granted a postdoc Fulbright scholarship to visit University of Pittsburgh and Hofstra University for novel research on AI and law.
Research Scientist (AI & Law)
CONICET – UNS
2012 - 2023
Conducted research on symbolic AI for context-sensible argumentation and dynamics applied to legal reasoning. Director of JuriSIA research group on applied Socio-juridics and AI. Over the past decade, I have extensively developed techniques to formalize legal argumentation. I’ve been speaker at recognized AI conferences like AAAI and IJCAI, and published over 37 scientific papers. To deepen my understanding of normative reasoning, I pursued a Master's degree in law focussed on legal reasoning.
