I work on high-throughput backend systems: queues, workers, and the observability you need when they start lying to you. Day job is email infrastructure at scale — warmup schedulers, IMAP sync, bounce processing, and the ClickHouse/Grafana layer that makes it debuggable.
Most of my open-source work is the same thing in someone else's codebase: throughput bugs, render/perf regressions, SDK edge cases, and the small correctness fixes nobody wants to chase.
22 merged pull requests across projects with a combined ~190k stars.
- Throughput and bottleneck debugging — finding why a queue backs up, a worker stalls, or CPU climbs, and proving the fix with dashboards
- Query optimization across MySQL, MongoDB and ClickHouse
- Distributed job pipelines — BullMQ/Redis schedulers, Kafka consumers, retry and dead-letter semantics
- Shipping MVPs solo, end to end, including the boring parts (payments, webhooks, auth, deploys)
- Github-Analyzer — turns GitHub data into readable contribution visualizations
- OpenRank — ranking layer for the open-source developer ecosystem
- SkillPack — one command for every agent skill you need
- Notus — records and transcribes meetings into structured notes and action items
Backend and infrastructure issues in TypeScript/Node projects — especially anything queue-, worker- or performance-shaped. Tag me on an issue and I'll take a look.
