Senior Software Engineer (2024 - Present)
- Maintained existing features and shipped new capabilities for Compatibility Matrix (ephemeral Kubernetes clusters for testing), SecureBuild (Zero CVE images) and the Enterprise Portal (customer facing portal).
- Developed CMX network policy reporting that surfaces source pod details (pod identity and command/PID running in pod) via eBPF/XDP and kprobes.
- Refactored CMX networking airgap using XDP hooks to enforce blocking at the NIC with XDP_DROP while retaining network policy reporting.
- Implemented a VM snapshot feature for CMX using Firecracker and OverlayFS.
- Built SecureBuild’s in-product package and image testing pipeline, validating artifacts before they’re added to the Zero CVE catalog based on melange’s existing package testing pipeline pattern.
- Contributed to LLM-assisted SecureBuild catalog image generation and subagent workflows by authoring Claude rules and skills to enhance generation accuracy.
- Orchestrated end-to-end Claude workflows using Conductor to speed up and streamline development.
- Rebuilt the e2e test suite in Go with Dagger, replacing the prior Bash-based implementation reducing flakiness and increasing test coverage.
- Improved the CMX history usage backend and frontend to deliver clearer cost-consumption reporting for customers.
Senior Software Engineer (2022 - 2024), Software Engineer (2019 - 2022)
- Spearheaded design and development on two Kubernetes operators (RethinkDB and MSR) plus a shared operator library built for easing installation and lifecycle management for MSR customers.
- Maintained MSR product integration in Mirantis Launchpad (internal Ansible-like solution).
- Built an integration test library using Gruntwork Terratest, Mirantis Launchpad, and Terraform.
- Performed competitive feature gap analysis of rival products with product and engineering.
- Helped design and develop the Mirantis Migration Tool, including components for concurrent blob storage copying, database transformations, and product deployment.
- Designed and implemented Running Image Enforcement, enabling RBAC-style rules to prevent Docker image pulls from any client.
Senior Software Maintenance Engineer (2019), Software Maintenance Engineer (2018 - 2019), Support Engineer (2017 - 2018)
- Founding member of the Support Engineering Group (SEG) at Docker: a sustaining development team.
