How I work

  • Own features end-to-end - APIs, UI, data models, and deploy - not just tickets in isolation.
  • Debug production issues with logs, metrics, and root-cause fixes (N+1 queries, timezone bugs, stale client state).
  • Optimize for real load: aggregation pipelines, event-driven jobs, and less polling where it hurts.
  • Ship with ops in mind - EC2, Nginx, PM2, S3, scheduled jobs, and CI when the product needs it.
  • Translate requirements for non-technical users so the system matches how the business actually works.

Work Experience

Junior Full-Stack Developer

July 2025 – Present
ABSS – Adaptive Business Support Systems LLP
  • Built a Teams-like web app for industry use - connecting people in one place with real-time chat, meetings, and task tracking for 50+ concurrent users (<100ms message latency).
  • Engineered real-time messaging using Socket.IO clustering + Redis pub/sub; implemented typing indicators, presence, and delivery receipts.
  • Built event-driven reminder system with BullMQ + Redis, replacing polling and reducing server overhead by ~90%.
  • Optimized MongoDB aggregation pipelines, cutting API response time from 2.3s → 400ms; fixed N+1 queries reducing DB calls from 15 → 2 per request.
  • Designed role-based access control with 12 permission levels across multi-company architecture.
  • Resolved production Ant Design Select rendering bug caused by stale Redux state; fixed IST timezone bugs affecting 200+ attendance records.
