Projects & Contributions
OpenFeature
Maintainer. OpenFeature is the vendor-neutral standard for feature flagging in the CNCF landscape (currently incubating). I’m active across the full org — contributing to the spec and SDKs in Java, Python, Go, and JavaScript, driving testing automation across that polyglot environment, and helping shape governance and roadmap.
In a previous role I architected and shipped a centralized feature flag management service built on OpenFeature, integrated it with OpenTelemetry for SRE-grade observability over flag evaluation, and represented the project at the KubeCon Project Pavilion.
flagd ecosystem
flagd is OpenFeature’s reference flag evaluation engine. The work below cuts across the polyglot test surface that keeps the ecosystem honest:
- flagd — 22+ PRs across the targeting parser, OFREP traces, observability, and architectural decision records.
- flagd-evaluator — 12+ PRs on the Rust + WASM cross-language evaluator that lets every SDK share one targeting implementation.
- flagd-testbed — 68+ PRs maintaining the gherkin-based cross-language conformance harness used by every flagd provider.
JUnit Pioneer
Maintainer. A JUnit 5 extension pack with an active contributor community — small, focused, and a good on-ramp for first-time open source contributors. Website
Keptn
Approver, lifecycle-toolkit. Keptn is a CNCF project for cloud-native application lifecycle orchestration. Granted approver status in 2023 for sustained work on documentation, linting, and project infrastructure (community PR 272).
- lifecycle-toolkit — 30+ PRs across the operator, docs, and CI.
- community — 14+ PRs on governance and contributor process.
- keptn.github.io — 31+ PRs on the project website and documentation pipeline.
OpenTelemetry Demo
The CNCF reference demo for distributed tracing. Contributed PR #2114 — adapting the load-generator to use the OpenFeature OFREP provider instead of the in-process evaluator, so the demo exercises a realistic remote-evaluation path.
JoustMania
Demo platform behind the KubeCon EU 2026 talk 18 Bluetooth Controllers Walk Into a Bar (with Manuel Timelthaler) — see /talks. A Raspberry Pi jousting game wired up as a live testbed for OpenFeature, runtime configuration, and observability tooling under genuinely chaotic input. Heavy involvement (440+ PRs) on the fork that drives the talk’s demos. Source repository
