Rockstar🎓
Top SchoolMark Esler is a Senior Engineer with 8 years of experience building secure, cloud-native systems and tooling across Python, Go, JavaScript, and Linux environments. Currently at Chainguard focused on product security, he brings deep infrastructure knowledge from prior roles at Canonical and hands-on lab and data-processing experience developing metabolomics software and operating mass spectrometers at the University of Minnesota. Comfortable across OpenStack, AWS, Ansible, DBMS/SQL and observability stacks like Grafana, he bridges low-level systems work (BSD/RHEL, networking, embedded C/C++) with modern API and frontend stacks (FastAPI, Node.js, D3). Based in Seattle, Mark combines a strong security-oriented product mindset with practical lab-to-cloud experience—an uncommon background that informs robust, reproducible engineering for scientific and production systems alike.
