Experience

Software Developer (SDE 1) & Forward Deployed Engineer

Jul 2023 — Present

Benchmark Computer Solutions Ltd · Andheri, Mumbai

  • Primary FDE across 3+ enterprise client lifecycles: requirements, system design, development, deployment and production support for 8+ enterprise applications.
  • Built a Unified Membership Architecture integrating multiple platforms under one identity and membership layer.
  • Led a team of 4 on an end-to-end solution with an integrated CRM: sprint planning, code reviews, architecture decisions and client communication. 100% on-time delivery, 30% higher client satisfaction.
  • Re-engineered the Exhibition Management System to sustain 1,000+ concurrent users at 480+ requests/sec with 0% errors.
  • Exhibition Management System: A large international trade exhibition: 20,000 daily visitors and 300,000+ attendees. I inherited a backend that collapsed at 40 concurrent users, four weeks before the live event. Throughput up 25×. 1.7M requests per hour with 0% errors under live peak traffic, validated by load simulations modelling 17,000 concurrent user workflows across 17 registration and ticketing journeys.
  • Database tier: Audited 2,000+ source files (22,888 anti-patterns) and eliminated per-request connection pools. Added capped pools, a 1,000-slot in-memory admission queue with 503 load shedding, and queue-wait vs. execution-time instrumentation. Layered timeout hierarchy: queue → pool → SQL → watchdog → proxy. Zero stored procedure changes.
  • Server architecture: Least-current-request balancing with intra-cluster spillover, CPU affinity isolating mail and CRM workers from API workers on Windows Server, and Redis-based cron leader election. Real-time cluster telemetry dashboard: event-loop lag, pool usage, heap, queue depth.
  • Redis and queue reliability: Root-caused recurring Redis ECONNRESET drops across idle timeouts, TCP backlog, WSL2 NAT IP drift and IPv6 dual-stack. Fixed BullMQ unresolved promises. Replaced a 130-line if/else dispatcher with 42 validated job handlers, plus job and SMTP timeouts.

Web Developer Intern

WEBAPPZAP · Mumbai

  • Built and maintained 3 websites using .NET and SSMS, boosting user engagement by 40%.

Freelance Web Developer
