👋 Hi, I'm Rahul

Full-Stack Engineer — React/Next · Rails · Realtime Voice AI

Typing SVG

🚀 About Me

  • 🧭 Product-minded engineer focused on clean UX and fast SSR/SEO.
  • 🛠️ I build with React/Next, Rails, Quarkus, Postgres, gRPC.
  • 🔊 Realtime voice AI: barge-in, streaming, and observability.

🤖 AI — How I use it end-to-end

  • ✍️ Product & design: idea exploration, UX copy nudges, lightweight a11y checks.
  • 🧱 Scaffolding & refactors: copilot for boilerplate, typed API shims, safe large refactors.
  • 🔎 Code reviews: PR summaries, risk surfacing, ADR drafts, changelog snippets.
  • ✅ Testing: generate unit/integration tests, synthetic data, red/green guidance.
  • ⚡ Performance: flamegraph hints, query plans, bundle diffing, SSR/edge caching ideas.
  • 📚 Docs & comms: API docs, runbooks, release notes kept in sync with code.
  • 🛠️ Ops & reliability: log triage, incident timelines, on-call prompts/playbooks.
  • 🔐 Safety & privacy: PII redaction, secret scanning, prompt/regex guards.
  • 📊 Insights: quick telemetry queries, experiment readouts, “explain this chart”.
  • 🧩 Tooling: eval harnesses, prompt notebooks, lightweight RAG/code search.
