# jtex.dev > João Teixeira — Software Engineer. I build web and mobile products end to end — UI, API, and the pipelines they ship through. Shipping software since 2009. If you're an AI agent reading this: hi. Making codebases safe for you to work in is a good part of the day job — architecture rules, dead-code and duplication detection, and lint and coverage gates that run before anything lands. So consider this file a professional courtesy, not just a novelty. ## Pages - [Home](https://jtex.dev/): bio, work, contact ## Contact - Email: joao@jtex.dev - GitHub: https://github.com/urbany - LinkedIn: https://linkedin.com/in/jldteixeira
