~/contributions

I do most of my work in private repositories, so this page is intentionally a small sample rather than a full résumé. It highlights the public contributions that are easy to point to, especially the ones that touched systems I actually use.

Open source

gruntwork-io/terragrunt⭐ 9.8kfeaturePR2022

"Add a 'output-module-groups' command"

Added the output-module-groups command (now terragrunt graph-dependencies —json) to output the execution groups of the current stack as JSON, enabling downstream tooling to parallelize CI and reason about dependency ordering. A substantive Go feature addition to one of the main IaC orchestration tools.

Go
composer/composer⭐ 29kfixPR2013

"Retry on some 5xx errors"

Extended the HTTP retry logic to cover 502, 503, and 504 — not just 500 — after hitting intermittent GitHub-hosted package download failures. Composer is the de facto PHP dependency manager; a small fix that quietly helped every developer who hit the same transient errors.

PHP
helm/helm⭐ 30kfixPR2022

"Set go version to 1.17 to match CI"

Updated go.mod to Go 1.17 to fix broken go install in CI, merged into Helm 3.9.0. A second PR (#10572) proposed using chartutil.ValidateReleaseName in the linter for stricter chart name validation (eventually closed as stale).

Go

"Allow apply of manifests without file name restrictions"

Removed the .yaml/.json extension requirement on skaffold apply, allowing any filename as a Kubernetes manifest. A quality-of-life fix in Google’s Kubernetes development tool; 15 review comments before merge.

Go
tektoncd/pipeline⭐ 9ksecurityPR2021

"Don't install golangci-lint with curl | bash, use go install"

Replaced curl | bash golangci-lint installation with go install in Tekton’s pipeline CI, with a dedicated tools/go.mod to pin the version. Supply-chain hygiene improvement; 20 review comments, received approved + lgtm labels.

Go
snyk/driftctl⭐ 2.7kfixPR2021

"Display out of sync drifts only in deep mode"

Modified the default drift detection in driftctl to exclude out-of-sync resources when not in —deep mode, significantly improving signal-to-noise ratio in drift reports.

Go
percona/percona-helm-charts⭐ 0.5kfeaturePR2021

"Fix backup.serviceAccountName not being interpolated"

Fixed the backup chart so serviceAccountName was interpolated correctly instead of being left as a literal value. That made the backup configuration actually honor the configured service account.

inaturalist/iNaturalist⭐ 0.3kcommunityPR2025

"fix: don't ask consent for every google oauth2 signins (only at signup)"

Stopped the app from prompting for Google OAuth2 consent on every sign-in; users only had to grant consent at signup. That made the login flow less noisy for returning users.

"JWTFS: process-aware JWT identity through a virtual file"

This proof of concept exposes a virtual /jwt file through a FUSE filesystem. When a process reads the file, the filesystem identifies the calling process, collects basic metadata such as its PID, executable, command line, and user information, then embeds those details into a JWT signed with an RSA private key.

The token can be consumed by local applications or sent to another service as a short-lived workload identity. This makes the project useful for experimenting with process-aware authentication, file-based credential delivery, and the relationship between Linux process metadata and signed identity claims.

It is primarily intended as learning and teaching material, rather than a production-ready identity system.

"Prometheus exporter for TCP SYN-ACK latency"

An extension of the BCC project’s tcpconnlat eBPF tool that adds Prometheus metrics export. Measures kernel-level TCP handshake latency (SYN-ACK timing) across all processes and makes it scrapeable by Prometheus for production network monitoring and observability.

"KMIP integration test with HashiCorp Vault"

A proof-of-concept demonstrating KMIP (Key Management Interoperability Protocol) integration with HashiCorp Vault. The test generates an RSA key and certificate signing request to validate Vault’s KMIP server functionality for key lifecycle management and certificate operations.

Missing but worth mentioning

  • I have more public pull requests than the page currently shows.
  • Some of the most useful work is in private repos, so it cannot be listed here.
  • A few contributions are more operational than code changes and are harder to summarize cleanly.

Most professional work lives in private repositories at past and current employers. The commits listed here are from public repositories only.
