Rockstar๐
Top SchoolTimo Glastra is a Co-Founder and CTO with nine years of hands-on software engineering experience, focused on self-sovereign identity and distributed technologies. He is finishing research on Hyperledger Aries and actively contributes to high-profile open-source projects such as indy-sdk and ACA-Py, where his work has improved message handling, multi-tenancy, and cross-platform compatibility. As a TypeScript and backend/security engineer, he has strengthened decentralized identity frameworks (e.g., credo-ts) by adding robust message dispatching and security-focused handlers. He co-founded two startups, balancing product leadership with deep technical contributions and CI/compatibility improvements across Node.js environments. Based in Utrecht, he combines applied academic grounding in IT with practical expertise shipping interoperable identity infrastructure. An underappreciated strength is his attention to type safety and developer ergonomics, evidenced by contributions to DefinitelyTyped that tighten TypeScript definitions for identity libraries.
