divyanshu sharma telemetry banner

yo, i'm divyanshu 👋

i'm a product builder & open-source contributor who likes shipping fast, zero-bloat software end-to-end. instead of boxing myself into a single language, i jump across the stack—from crafting reactive web & react native interfaces to diving deep into backend systems, llm proxies, and database internals.

  • open source (40+ merged prs): heavy contributor to clawvisor (yc p26) (where most of my prs live), currently hacking on postgres search internals at paradedb, and shipped across openwork, mem0, and inth/c15t.
  • industry experience: built clinical dashboards, bullmq queues & aws ses/sns event pipelines at rockethealth (migrated 6k+ users), hardened llm proxy infra at clawvisor, and built ai travel engines at zingvel.
  • off the clock: watching f1 telemetry, dialing in guitar tones (the 1975 / radiohead), and football tactics.

🏎️ open-source & engineering log

i like dropping into unfamiliar, high-velocity codebases, figuring out how they tick, and shipping real fixes:

organization / repo what i shipped & worked on repo stack
🔴 clawvisor (yc p26) top contributor (most merged prs) — built & hardened llm proxy infrastructure, resolved high-concurrency sqlite contention under 200+ req/sec (wal tuning, connection pooling, busy timeouts), added headless runner wait apis with token budgeting, and built reactive approval telemetry panels. golang sqlite typescript sse
🟠 paradedb active contributor — working on postgres BM25 search & analytics engine internals, query predicate execution, and memory/filter optimizations. rust postgresql search
🟣 openwork (different-ai) contributed desktop application features, rich release note rendering, and update notification workflows. typescript react desktop
🔵 mem0 & inth/c15t engineered reactive frontend surfaces, telemetry components, consent/state flows, and developer tooling across 40+ total oss prs. typescript next.js react
🟢 rockethealth full-stack developer across 5 clinical verticals; built rocket-mail with aws ses/sns event tracking, bullmq job queues (invoices, notifications, meta events), and migrated 6k+ users. next.js bullmq node.js aws
⚪ zingvel travels built interactive flight seat pickers, responsive ticketing flows, and wanderlust—an ai-powered travel recommendation engine. react typescript ai

🛠️ things i've built from scratch

projects where i owned the product design, frontend experience, and backend architecture end-to-end:
