Delta Exchange

Worked on a high-traffic, real-time trading platform used by hundreds of thousands of active traders globally. The frontend acted as a long-running system handling live market data, compliance rules, and performance-sensitive workflows.

  • Led migration of 500k+ existing users to the India-specific platform by designing geo-based routing, compliance gating, and seamless fallback flows.
  • Built and maintained location-aware onboarding that routed 600k+ new sign-ups across platforms based on jurisdiction, reducing manual intervention and support load.
  • Designed trading analytics dashboards consumed by 100k+ active traders, optimized for frequent data updates and minimal re-renders.
  • Debugged production-only issues caused by rendering loops, unstable references, and state churn under real market load.
  • Collaborated closely with backend and compliance teams to ensure correctness under regulatory constraints without sacrificing UX responsiveness.

DilSayCare

Founder & Engineer · Mental health platform

Built an AI-assisted mental health platform from scratch, owning frontend architecture, backend systems, infrastructure, and product flows.

  • Designed chat-based mental health assessments that behave like stateful conversations rather than static forms.
  • Implemented real-time WebSocket flows for assessments, follow-ups, doctor recommendations, and session booking.
  • Architected backend systems using Node.js, PostgreSQL, and Redis, with strong guarantees around correctness, ordering, and data recovery.
  • Designed slot-based scheduling logic for therapists and institutions, supporting both online and offline sessions.
  • Focused heavily on failure handling — dropped connections, partial submissions, retries, and reconnection logic.

Frontend Engineer · Salary insights platform

Worked on a consumer-facing salary insights platform where SEO, performance, and rendering correctness directly impacted growth.
