Software engineer @ 9D Technologies in Lahore, Pk. I write Python and FastAPI services, the CI/CD that ships them, and the telemetry that explains them when they break. Most of my open source work lands in large, long-lived codebases: container images, build systems, CI, and the accessibility bugs everyone had learned to live with. Lately, LLM agents that are only allowed to do what they can prove.

I debug systems by reading traces, so this is my history the way Jaeger would draw it. Each role is a span; the live ones keep growing.
Open any span on the interactive version.
Every one of these is running or merged somewhere you can check.

Env var substitution in the Jenkins image Opt-in substitution for reference config in containerized Jenkins, closing a request open since 2017. I followed it with Windows parity in PowerShell: 🚢 Shipped in Weekly 2.565 and LTS 2.568.1 · #2250 ↗ · #2365 ↗ |
FOSSology microservices Revived a branch frozen since 2021 and ran the scheduler, database and agents as 10+ services on Kubernetes, with a Kustomize base across 26 manifests. Moving from Make to CMake cut build time by 40%. The hard part was a scheduler crash loop, traced through schema limits, container networking and init ordering. ☸️ 10+ services · −40% build time · Final report ↗ |

SigNoz AI SRE A self-healing loop driven by SigNoz alerts. Rules fix known failures. Unknown ones go to an LLM with two read-only tools, a three-key action allowlist and a 10-second timeout, and its proposals pass the same safety check a human's would. Every model call is a traced span. 🤖 Gemini · Claude · GPT behind one interface · Watch it run ↗ |
PoS-OTel Jenkins exports traces to an OpenTelemetry Collector that keeps every failed build, every build over 30 seconds and 20% of the rest. Traces go to Jaeger; span metrics feed Prometheus and Grafana. I built it after an afternoon of correlating container logs by hand during GSoC. 📉 −81% trace data across 9 pipeline runs · Source ↗ · Simulator ↗ |

Ezvor A career platform that scores readiness only from work a judge has verified. It combines a 3,977-problem graded DSA arena with live GSoC, LFX and Outreachy status. The score is a pure function of the evidence, with no model and no network calls, so it can't be gamed. |
PDF Scanner Web The web side of PDF Scanner, an Android app with 50M+ installs. It has 31 document tools, including merge, compress, OCR, sign and redact, and every one runs in the browser. Files never leave the device, so there's no conversion server to run. |

|---|---|---|---|
 |
Jenkins | 5 | Opt-in env var substitution for the official Docker image, closing a 2017 request, then Windows parity in PowerShell with Pester tests. Both ship in Weekly 2.565 and LTS 2.568.1. Keyboard-navigation and ARIA fixes in core. |

 |
OWASP Nest | 1 | Collaborator since Jan 2026. Focus-visible accessibility reports, the GSoC 2026 mentor list, and a security issue disclosed privately. |
 |
FailureTwin | 1 | Put a live LLM analysis path in front of the deterministic engine and kept the engine as the fallback, with no secrets in the client bundle. |
 |
sktime | in review | Sporadic optimization bracket errors in BoxCoxBiasAdjustedForecaster. |
 |
NumFOCUS | 1 | Edits to the DISCOVER Cookbook, the guide for inclusive conferences. |
 |
TYPO3 | 1 | Reworked the testing framework docs and removed deprecated Nimut references. |
Plus 1 more in meshery/meshery.

I spent a summer building a complete microservices infrastructure for FOSSology: scheduler, database and agents running in Docker and Kubernetes. It taught me distributed systems and configuration management, but mostly what happens when you don't have observability. That is the reason I later built PoS-OTel.

|---|---|---|
| Bonding | #300 | Kickoff, 1:1s with mentors Soham and Avinal, closed out #1299, local environment ready by May 31. |
| 1 | #314 | Docker, Minikube and kubectl on Ubuntu 24.04. Rebased Omar's 2021 branch. Build failures, a stale etcd image, and the web UI serving Debian's default Apache page. |
| 2 | #319 | Tried bookworm-slim, rolled back to buster-slim, fixed file paths, built every base image. Then db-0 stuck in Init. |
| 3 | #327 | Missing libcurl in the scheduler build, web starting before PostgreSQL, a schema crash. First working UI. |
| 4 | #330 | Minikube → Kind for a faster loop. First implementation up for review. Scheduler still in CrashLoopBackOff. |
| 5 | #340 | Crash loop fixed for good. Next: the web pod resolving PostgreSQL via localhost instead of the service. |
| 6 | #346 | PHP config and DB connectivity from pod logs. Agreed the Make → CMake move with mentors. |
| 7 | #349 | Most components building under CMake, the scheduler the last failing image. Passed the midterm. |
| 8 | #355 | CMake on Bookworm, back to Minikube, synced with master. Manifests for four missing agents. |
| 9 | #364 | Missing DB columns for the web agent, a curl health check for the scheduler, a clean Dockerfile.ojo. |
| 10 | #365 | Scheduler partially functional. Kustomize restructure started. Consulted the original 2021 contributor. |
| 11 | #371 | A Kustomize base with dev and prod overlays across 26 manifests. |
| 12 | #372 | Remaining instability traced to install path mismatches. Rebuild versus incremental fix, weighed. |
| 13 | #373 | Legacy vs modern scheduler compared, last failures traced to upstream migrations. Final report. |

Every PR outside my own repos →
Deterministic first. Known failures take a plain if/else. The model only sees what the rules can't explain.
Guardrails live outside the model. A small action allowlist, read-only tools and a hard timeout. Safety comes from a small action space, not from trusting the output.
Every model call is a span. The model, token counts and each tool call are traced next to the infra they investigated, so cost is a query.
Fallbacks are part of the contract. No key, a timeout or a bad answer resolves to "needs a human". In a live run, my agent found no evidence and declined to act.
