Software Developer at Axiros who migrated legacy C++ to Rust and built telecommunications apps and network tools.

At Axiros, I contribute to remote management products for cable modems and network hardware, including a migration of legacy C++ code to Rust and a speed test server and client built to TR-143 and TR-471 standards.

I created mobile apps for telecommunications customers and technicians, along with an Android library that companies can embed to monitor network quality and diagnostic metrics.

At Pio Lindo, I designed and built an enterprise management system for a poultry business, covering inventory, logistics, imports and exports, and HR and payroll operations.

On receptIA, I designed a multi-tenant SaaS that provisions a dedicated AWS server for each doctor and connects a Go assistant to OpenAI and Gemini. I also built Photo Converter, a Rust desktop app for batch image conversion.
