<h2>About me</h2>
<div class="about-bio">
<p class="about-lead">I’m Yuval, a software developer with a mechanical engineering degree. I work on algorithms, Python systems and applied AI.</p>
<p>From July to September 2026, I worked full-time on a UGV defense project. I developed shared Python backend and operator interfaces for command handling, telemetry and diagnostics, with logging across four components, thread-timing diagnostics, watchdogs and heartbeat handling.</p>
<p>At BGR Formula Student, I led planning and control from 2023 to late 2025, sharing implementation with the team. We achieved approximately 50 metres of physical autonomous driving using ego-centric navigation without a functioning IMU.</p>
<p>I like turning an unclear problem into a model I can inspect, a first version I can run, and an experiment that tells me what to change.</p>
