Software engineer working close to the metal — Linux systems, virtualization and test automation by day; web development and security on the side.

Where I've worked

2024 — present

GPU Software Engineer @ Intel

One of four engineers who built an end-to-end GPU validation environment from scratch — now supporting driver validation across teams.

Started from an empty repo with three teammates; a year later it’s load-bearing.

I own the automation end of a from-scratch validation environment — machine provisioning, test execution and results handling in Ansible and Python — live in under six months where no end-to-end testing existed before.
I automate real user-scenario validation: driver benchmarks, games and desktop apps across multiple GPU generations, replacing work people used to do by hand.
I implemented and automated GPU virtualization testing with SR-IOV.
As the scope widened, I kept building automation and new features across the team’s tooling — multi-cluster test runs with Slurm among them — and co-own all the CI/CD.
I’m consolidating the separate tools into one platform wired into the testing infrastructure already in place.

DevOps Engineer @ Solwit SA

I built and ran CI/CD pipelines for fuzz-testing Node.js microservices.

I ran fuzz tests on Node.js microservices and took coverage from roughly 5% to 70%+.
I reworked the pipelines to reuse already-fuzzed data instead of starting over each run.
I automated the code-coverage reporting so the numbers showed up on their own.

2022 — 2024

Software Engineer @ Solwit SA

I improved and ran a High Performance Computing (HPC) testing environment, plus the small tools the team needed around it.

Day-to-day this was part tooling, part keeping the environment honest across distros.

I built features in Bash and Python, and three full-stack web apps for everyday team tasks.
I taught the team web development and reviewed their Bash and Python.
I automated CPU/GPU pinning to squeeze out maximum performance, and synced with internal testing services using Python and GitHub workflows.
I integrated new open-source and internal HPC applications, then debugged and isolated issues in specific components.
I tested across RHEL, SLES and Ubuntu.

Web Developer @ Freelance

I run a one-person web studio — static sites for individuals and small businesses, design to launch.

Design gets the most of my attention — layout, type, and how a site actually feels to use.
I build in Astro + Tailwind and design in Figma, targeting 95+ PageSpeed on every client site.
One client, one site at a time, hands-on from first sketch to launch and the support after.
