Tech Solutions.I'm a software developer and technology solutions specialist with 12+ years of experience across Python, JavaScript/TypeScript and Rust, plus their main frameworks. I'm the founder of ImmutableLog, a security, audit and event observability platform built on a cryptographic ledger, the author of 10+ open-source Python packages on PyPI, and I build everything from event-driven microservices and microfrontends to distributed systems and developer tooling in Rust. My passion for technology and my desire to create positive impact guide my daily work.
