I'm a PhD physicist turned infrastructure engineer. I maintain a 40+ node Linux fleet for an open-source blockchain project; covering automation, monitoring, deployments, and public services. I also run a small web-hosting business and have built cloud automation for bare-metal onboarding and Kubernetes-hosted VMs at a startup.

My earlier work was in computational biophysics, ML, and HPC.

I'm looking for a hands-on platform, infrastructure, SRE, or DevOps role, ideally on a small, collaborative team. I'm also interested in research or ML infrastructure roles where my scientific background would be useful. Having worked at startups in the past, I'm fine wearing multiple hats and enjoy the variety.

Remote: Preferred

Willing to relocate: For the right role, though I'd prefer to stay in the PNW.

Technologies:

    * Languages: Python (proficient), Bash (proficient), JS/Go/SQL (familiar)
    * DevOps: Kubernetes, Ansible, Docker, Zabbix, DNS (TinyDNS/BIND), Harvester, Netbox, KeaDHCP, CI/CD, GHA
    * Platforms/infra: Linux (Rocky/Debian/Arch), Hetzner, AWS, Colo/On-Prem
    * HPC/ML: SLURM, Ceph, TF/Keras/PyTorch
    * Biophysical: GROMACS, OpenMM, FoldX, PyRosetta

Hi, I'm Jonathan, a PhD physicist who moved into infrastructure.

I run infrastructure for an open-source blockchain project where I manage 40+ linux nodes covering provisioning, virtualization, DNS, monitoring, deployments, and user-facing services. I also operate a small web hosting business where I own the full stack from bare metal up. Before this, my background was postdoctoral biophysics and ML research (GROMACS, SLURM, ML-assisted free-energy prediction) plus contract cloud engineering at a startup.

I'm a strong fit for platform, infrastructure, SRE, DevOps, or computational research roles. I do my best work in small, collaborative teams, and I'm comfortable wearing many hats.

Hi, I’m Jonathan. I’m a PhD-trained technical generalist focused on Linux systems, DevOps, infrastructure automation, and practical Python tooling.

I currently do infrastructure work for an open source blockchain project, run a small web hosting/IT consulting company, and maintain my own infrastructure from hardware and virtualization up through DNS, monitoring, deployments, and customer-facing services.

I’m a good fit for platform, infrastructure, SRE, DevOps, or computational research roles. I thrive in small, collaborative teams and having worked at startups before; I'm fine with and enjoy wearing many hats.

Hi, I'm Jonathan. I’m currently doing DevOps work for an open source project, operate a small web hosting company, and working as an accounting assistant for a local firm. My skillset is focused on the System Administration/DevOps side, with a bit of general dev experience primarily with Python. I have a PhD in Physics with my research focus being computational biophysics. On the side I also host my own infrastructure as a hobby, from the hardware to the nameservers and everything in between.

Having worked at startups before, I’m comfortable wearing many hats (and enjoy the variety).
