What I'm looking for

I'm available for remote work and projects.

I built TemNaLoja, an Android marketplace with a Firebase and Cloud Functions backend, Firestore, a web administration dashboard, and Mercado Pago integration. I also integrated the Meta WhatsApp Cloud API for automated customer service, supplier searches, and message handling.

At AmazonClip, I diagnosed and stabilized AWS and Contabo services and maintained a Python/Whisper transcription worker. I also delivered Android apps for Stella and developed PerinJobs and TakeDream as independent projects.
