What I'm looking for

I'm looking to build reliable cloud, payments, and applied-AI products, solving complex backend and integration challenges with modern .NET and Azure architecture.

I've built payment-core APIs at Pagar.me (Stone Co.), Pagou Fácil, and Incentivale, delivering Visa, Mastercard, Google Pay, Apple Pay, Pix, and Itaú Bolecode integrations. My work has supported thousands of low-latency requests per second, 99.9% uptime, 30% higher payment conversion, and zero-loss tokenized-card migrations.

At Dotkon, I architected a multi-tenant conversational scheduling assistant using Azure OpenAI, Microsoft Foundry, ASP.NET Core, Azure Container Apps, PostgreSQL, WhatsApp, Google Calendar, and Whisper. I also improve delivery and reliability through observability, CI/CD, DDD, secure integrations, and cloud modernization.
