I've led platform development at Veritas Automata, building an internal smart-locker activation system and certifying device authenticity on Hyperledger Fabric. I deliver production features and fixes through Kubernetes-based CI/CD pipelines.

Across Two's Complement, Gorilla Logic, and Growth Acceleration Partners, I've built Ethereum smart contracts, NFT image-generation pipelines, GraphQL modernizations, payment integrations, and analytics products. I also lead distributed teams, mentor engineers, and own delivery from architecture through production support.
