Worked primarily as a contractor for Celo, performing DevOps and infrastructure tasks similar to those in my later role at cLabs. Also coordinated the work of other Keyko contractors contributing to Celo projects. Collaborated with several blockchain networks, including Nevermined, Filecoin, and Masa, assisting with the deployment and configuration of their core infrastructure components. Built and maintained internal Keyko services, including Validators for various blockchain networks, Indexing infrastructure based on The Graph, and CI/CD systems for internal projects and clients.

Developed the Compute-to-Data system, enabling third-party algorithms to run securely on private datasets while preserving data confidentiality—a core feature of Ocean's data sharing protocol. Led the deployment and launch of a new blockchain network based on Parity’s OpenEthereum, ensuring stability and performance from testnet to mainnet. Owned and maintained all infrastructure operations, including blockchain nodes, supporting services, and CI/CD pipelines, with a focus on reliability, automation, and scalability.
