About
I'm Tiago Estrela Lauer, a software engineer from Brazil. I work across mobile, web and backend systems, moving between React Native, TypeScript, Vue, .NET and the infrastructure that keeps products running. I like the point where a feature stops being a prototype and starts carrying real users.
My work is measured in what survives contact with production: smaller bundles, faster deployments, stable interfaces and code that another engineer can understand without a guided tour. I've built mobile apps used by more than 10,000 people, worked with large real-time datasets and led teams through architectural and delivery decisions. Performance is not a final polish for me; it is part of the design.
I started in QA, which shaped the way I build: question assumptions, look for the failure mode and make the result observable. Outside a day job, I write about engineering, experiment with open source and build the small tools I wish existed. I care about clear systems, direct communication and leaving a codebase stronger than I found it.
