Hi, I'm Leo —
Brazilian-Italian engineer with 8+ years shipping production systems — from L2 rollups and ZK protocols to Kubernetes clusters and AI-powered apps. When I'm not building, I'm kitesurfing or exploring somewhere new.
I'm a Brazilian-Italian software engineer who loves to travel and catch wind on a kite. Over the past 8+ years I've worked across the full stack — from orchestrating Kubernetes clusters and building API gateways to architecting L2 zkEVM rollups and shipping mobile apps.
I was an early engineer at Rootstock Labs (formerly IOV Labs), where I built DeFi tooling and protocols for Bitcoin's smart contract layer. I've since gone deeper into ZK cryptography — designing privacy protocols on Solana, exploring the Polygon AggLayer, Linea, and OP Stack rollup ecosystems — while also contributing to Kubeshark, the API traffic viewer for Kubernetes.
I've consulted across education, health, energy, and construction, and touched ecosystems from Ethereum and Polkadot to Solana and Hyperliquid. These days I'm focused on AI-powered products and the intersection of infrastructure, cryptography, and machine learning.
I wear many hats — and I like it that way. The best solutions come from understanding every layer of the stack.
Worked on L2 zkEVM rollup infrastructure including Polygon AggLayer integration, Linea, and OP Stack rollups. Focused on bridging, sequencer design, and cross-chain interoperability at the protocol level.
Built core developer tools and DeFi protocols for the RSK Network — Bitcoin's smart contract sidechain. Contributed to ecosystem infrastructure, smart contract libraries, and developer experience across the Rootstock stack.
Contributed to Kubeshark — the API traffic viewer for Kubernetes. Think Wireshark re-invented for K8s. Worked on traffic capture, protocol dissection, and real-time observability features for cloud-native environments.
Helped build Ibble — an app designed to spark social discussions and knowledge sharing across communities. Worked on backend services, real-time features, and the mobile experience to support scalable, threaded conversations.
Contributed to Qwire — the entertainment industry's music rights management platform. Built backend services and integrations for managing licensing workflows across film, TV, and advertising.
Designed a ZK-shielded vault system on Solana with Merkle tree commitments, nullifier-based double-spend prevention, and sharded storage. Migrated from PLONK to Groth16 for production verification. Features cross-device deposit recovery via deterministic secret derivation.
A weekend hack project exploring spot-perp basis and funding rate arbitrage on Hyperliquid. Built tooling to test automated strategies, backtest signals, and understand DEX microstructure. Pure curiosity-driven tinkering.
Live experiments and proof-of-concepts. These are things I built to learn, explore, or just because they were fun.
Interactive visualization of how zero-knowledge proofs work — from circuit compilation to proof verification. Learn by doing.
