What I'm looking for

I'm looking to expand my skills while working with an outstanding team of developers to build next-generation, efficient, stable, and robust systems.

At Smartnumbers, I develop and maintain monitoring, alerting, billing, and production services in Rust, Go, and TypeScript, including AWS CDK deployments and OpenSIPS SBC software.

Previously at Intenda, I improved software efficiency and stability, supported QA and post-production systems, and wrote a C++ ODBC driver for a database federation platform.

My engineering background spans embedded C/C++ systems, Linux kernels, QNX, Yocto, microcontrollers, server-side applications, and front ends. I focus on efficient resource use and stable, robust systems while continuing to expand my skills with strong development teams.
