I make software tell you what's wrong with your software.

Backend engineer at SigNoz (open-source observability, 31K+ ⭐) — writing Go that runs on 2,000+ Kubernetes clusters I will never see, which is exactly as terrifying as it sounds. Everything I build ships to both our cloud and to self-hosted installs run by strangers on the internet. Distributed systems keep you humble.

• Infrastructure Monitoring at SigNoz — built the Hosts + Kubernetes monitoring end to end: from the Helm charts that collect metrics on customer clusters, through ClickHouse query APIs, all the way to the frontend. Containers ↔ pods ↔ nodes, all correlated, all fast(ish — ClickHouse cardinality is a lifestyle, not a problem)
• Alert channel integrations — Google Chat, Jira, JSM Ops, incident.io. When your pod dies at 3 AM, one of my integrations is probably the reason your phone buzzed. You're welcome. Sorry.
• signoz-otel-collector — the ingestion pipeline. Span metrics, delta temporality, schema migrations. The unglamorous plumbing that everything else depends on.

My favorite kind of PR is one that ships in five languages:

• Implemented is_remote span flags in the OTLP exporters of Go, JavaScript, Rust, Ruby, and Erlang — so tracing backends can spot service boundaries and draw service graphs straight from trace data. No more maintaining topology state by hand 🎉
• W3C trace-flags work in opentelemetry-go, plus a Prometheus metric-shape fix in the Operator that I drove from feature gate → beta
• Apparently 20+ contributions/year gets you a vote in the OTel Governance Committee election, so I have opinions and a ballot now

• Cold_Emailer — a Go pipeline that finds companies via Apollo, writes personalized outreach with OpenAI, and sends it through Gmail. Built it to automate the most soul-crushing part of job hunting. The irony of an observability engineer building an email pipeline with comprehensive logging is not lost on me.
• Previously: co-founded an NFT analytics platform (5,000+ wallets in 2 months, RIP), built no-code KYC orchestration on Temporal.io at FinBox, and once trained a GAN at Citibank to catch fraudsters
