Related infrastructure:
My merged TreeTracker contribution integrates Keycloak authentication with Hyperledger Fabric identity operations.
Keycloak • JWT authentication • Fabric CA • wallet management • API endpoints • Docker • security configuration
Kubernetes-based Hyperledger Fabric infrastructure covering certificate authorities, peers, orderers, CouchDB, channels, connection profiles, and chaincode lifecycle.
Grafana = Fabric health and performance
Prometheus = metrics collection
Alertmanager = operational alerts
Hyperledger Explorer = blockchain visibility

Productionization work across the TreeTracker and Hyperledger Fabric stack:
- TreeTracker web, admin, authentication, capture, and token services
- Kubernetes and Argo CD GitOps
- GHCR image delivery
- PostgreSQL and Keycloak migration and persistence
- Fabric peers, orderers, CAs, CouchDB, and wallets
- Hyperledger Explorer and CouchDB Fauxton
- Headlamp, Prometheus, and Grafana
- Backup, restoration, credentials, and persistence documentation
Related delivery tooling:
My TreeTracker Wallet work covers GitHub Actions CI/CD, Docker builds, security scanning, SBOM generation, and Kustomize deployment overlays.
My Prometheus, Grafana, Loki and Alertmanager deployment repositories are derived from my running Hyperledger Fabric / TreeTracker stack. SigNoz is an additional deployment package. Each includes Helm charts, native Kubernetes manifests, Terraform and OpenTofu deployments, high-level architecture, and operations runbooks.
Prometheus, Grafana, Loki and Alertmanager were validated in an isolated cluster: metrics collection, 15 Grafana dashboards, log ingestion and queries, alert handling, and persistence across pod restarts. Production profiles document their storage, identity, availability, and recovery requirements.

The recovered Harbor and TBench workspace contains 221 task/project directories after obvious template and test scaffolding are excluded. I use this portfolio to demonstrate breadth across secure systems, software engineering, infrastructure, distributed systems, and AI-agent evaluation.
Portfolio accuracy note: the 221 figure represents recovered task/project directories. It is not presented as 221 accepted benchmark submissions. Historical month grouping is based on current workspace timestamps and should be treated as an approximate timeline.
Engineering work includes:
- Task authoring and proposal development
- Proposal grading and technical review
- Reviewer guidelines and calibration
- Packaging and external-submission work
- Containerized execution environments
- Oracle and reference-solution engineering
- Separate-verifier and acceptance-test hardening
- Rubric and behavioral validation
- Failure-mode and regression analysis
- Reproducibility and edge-case testing
- Multi-step agent tasks with interacting invariants
