His enterprise work includes medical and utility-sector systems (FHIR vaccine QR codes, carbon management, CIM) using FastAPI, Flask, Laravel and PostgreSQL, while maintaining strong test coverage practices with pytest and PHPUnit. A frequent conference speaker and author of a PHP web-scraping book, he translates complex engineering topics into practical guidance for peers. He’s particularly adept at modernizing legacy codebases and CI pipelines—evidenced by migrating tests to GitHub Actions and unifying code style across libraries. Outside projects he runs a development blog, blending teaching with continuous experimentation in web security and tooling.
