About Sownak Roy

Engineering leader with 20 years' experience across DevOps, cloud-native platform engineering, and distributed ledger technology. I build infrastructure that other engineers build on and I lead the teams that deliver it.DevOps & Platform Engineering: Creator of Hyperledger Bevel (github.com/hyperledger/bevel), an open-source platform automating complex blockchain network deployments on Kubernetes across AWS, Azure, and GCP. Bevel is fundamentally a GitOps tool — declarative infrastructure, Git as source of truth, Helm charts, Ansible playbooks, and Terraform provisioning. At Accenture, I led the DevSecOps transformation for the Blockchain & Web3 Group, establishing CI/CD pipelines, infrastructure-as-code standards, and container security practices that reduced deployment times by 60%. AWS Certified Solutions Architect.Distributed Ledger Technology & Decentralized Identity: Architect and technical lead for cheqd's decentralized identity platform — blockchain infrastructure for DIDs, verifiable credentials, and trust registries built on Cosmos SDK. Designed privacy-preserving payment rails integrating W3C verifiable credentials with on-chain settlement. Deep hands-on experience with Hyperledger Fabric, Hyperledger Besu, Ethereum smart contracts (ERC standards, asset tokenisation), R3 Corda, and the Hyperledger Indy/Aries stack for self-sovereign identity. Led cross-platform interoperability work with Hyperledger Cacti and ACA-Py, establishing credential architecture patterns now used across enterprise implementations.Engineering Leadership: Led a 15+ member engineering team at Accenture delivering enterprise blockchain solutions to Fortune 500 clients. Grew Hyperledger Bevel from a 3-person side project into a Linux Foundation incubation project with 100+ contributors worldwide, managing roadmap, governance, release processes, and community across organisations. Mentored 10+ engineers through the Linux Foundation Mentorship programme. At cheqd, I lead the entire engineering function across two products as a player-coach — setting technical strategy, making architectural decisions, and shipping code alongside my team in TypeScript, Golang, and Python.Currently exploring new opportunities in engineering leadership, DevOps/platform engineering, and DLT architecture. Open to both hands-on technical and leadership roles.Core technologies: Kubernetes, Docker, Helm, Terraform, Ansible, GitHub Actions, AWS, Azure, GCP, Prometheus, Grafana, Hyperledger Fabric, Hyperledger Besu, Cosmos SDK, Ethereum, Solidity, TypeScript, Golang, Python, Node.js
