Software Contracting

Embedded and systems software that ships.

Hi, I'm Matt Beisser. I'm a staff-level software engineer who has been shipping C++ since 2008 and Rust for the last few years, mostly on embedded and performance-critical systems. Bitrealm LLC is how I contract that work out.

Available for part-time and project-based engagements.

Embedded and systems code

C++ and Rust on Linux, from device modules and packet processing to the build systems and tooling around them. I've ported firmware from an RTOS to Yocto and moved a million-line codebase across four compiler generations.

Safety-critical and regulated

Lidar software for a production vehicle, with ISO 26262 verification evidence and Automotive SPICE process work before an audit. Fuel distribution software, governed by custody transfer, weights-and-measures law, and bills of lading.

Performance and failure analysis

Profiling with perf and flame graphs, worst-case execution time fixes on real hardware, and diagnostic pipelines that turn raw telemetry into an explanation of why a sensor failed.

Where the
experience
comes from

Luminar Technologies, 2021 to 2025
I was a staff software engineer on lidar software for the Volvo EX90. I owned two core modules, including the design, testing, and ISO 26262 ASIL B verification evidence, then led a four-person team building a diagnostic data platform in Rust.

Toptech Systems, 2012 to 2021
Nine years on a million-line C++ product that runs fuel terminals for ExxonMobil, Shell, TransMontaigne, and others. I shipped customer features to hundreds of sites, led design reviews and estimation for the project team, and finished as one of three engineers porting the flagship controller from a real-time OS to Linux.

Lockheed Martin, 2008 to 2012
Simulation software for Army and Marine Corps training programs, my first job out of school.

Education
B.S. Computer Engineering, University of Central Florida.
