Experience
Volunteer at Open Source Software
I created and maintain many open source projects that are used heavily throughout industry and academia. I also care deeply about the Python and Rust communities and try to improve the ecosystems of both.
Highlights
- Python bindings for libsecp256k1, which serves as the crytographic backbone of many projects, including the entire Ethereum Python community
- A package manager and build system for Python that solves long-standing pain points for users and has been adopted by Python's official packaging team
- Highly optimized Kubernetes CSI driver for mounting Google Cloud Storage buckets that Google credits in the design of their official driver
- Authored PEP 631 which defines the standard way to specify dependencies for Python projects

Senior Software Engineer at Datadog
Datadog is the leading monitoring and security platform for bringing together end-to-end traces, metrics, and logs to make applications, infrastructure, and third-party services entirely observable.
Highlights
- Acquired expertise with many technologies in order to create integrations such as for Envoy, ClickHouse, CockroachDB, Vault, Hyper-V, and TLS itself
- Implemented the Agent's novel circuit breaker and exponential backoff logic, making our backend more resilient to failures and decreasing provisioning requirements
- Built a public docs site for Integration developers from scratch, which is now referenced by the official documentation
- Architected the E2E tooling for Agent Integrations, allowing anyone to spin up and test production environments with a single command
- Ensured the CI infrastructure ran smoothly and was optimized for 3 large monorepos with the most recent rewrite reducing runtime by 30% and saving thousands every month
- Improved our Helm chart generator and Bazel linter based on the needs of various teams, easing CNAB adoption and making deployments less error-prone
- Introduced memory profiling facilities that made it easier to discover the source of memory leaks
- Routinely gained expertise in different domains in order to do large-scale rewrites of core components, such as for OpenMetrics and Windows performance counters, which always significantly improved performance and ease of onboarding
- Created our own Python package index for CI/CD purposes that is served by GitHub Pages with artifacts cached by Cloudflare, which does not cost anything to run and has experienced zero downtime since creation
- Conducted dozens of engineering interviews and graded a similar number of take-home tests, ensuring our hires are exceptional in both technical ability and character
