Backend engineer focused on distributed systems and high-throughput infrastructure. Currently Founding Software Engineer at Openleaf (Mumbai), where I design and ship production systems across logistics, e-commerce, and AI/LLM integrations.

• Building on a 322-table PostgreSQL schema serving 13+ carriers, 9+ e-commerce channels, and 5 WMS integrations
• Shipped systems processing millions of events: BullMQ concurrency=128, AWS SQS FIFO, Redis multi-tier caching
• Integrated LLMs (Google Gemini, Claude 3.5 Sonnet) into production document intelligence and B2B automation pipelines
• ICPC Asia Taiwan 2024 — India Rank 3, Asia Rank 99

Carrier Pricing Engine — Go · PostgreSQL
Hierarchical lookup across warehouse → pincode → city → zone → state → region with 40+ charge types, bidirectional route matching, and carrier-specific volumetric divisors.

LLM Document Intelligence Pipeline — Google Gemini · Claude 3.5 Sonnet · IMAP · Focus8 ERP
Ingests POs, GRNs, and invoices from email; classifies document type, extracts SKU tables from multi-page XLSX with zero-tolerance PO number accuracy, and syncs to ERP. Separate Claude integration with prompt caching resolves ambiguous B2B customer mappings via streaming API + exponential backoff.

32-Carrier Shipment Tracking System — BullMQ · Redis · Node.js
Two-tier Redis cache (1h config TTL / 7-day immutable field TTL) eliminating 2 serial DB round-trips per job tick. Parallelised 4 terminal-state writes with Promise.all saving ~7ms/job. 13-carrier NDR workflows integrated with Bitespeed, Contlo, ElasticRun, SagePilot.

Shopify Order Ingestion Service — Go · AWS SQS FIFO · PostgreSQL
Exactly-once delivery via FIFO queues between webhook producer and order consumer. Replaced N+1 image cache lookups with batch queries, converted O(n²) tag-matching to O(n+m) map lookup, singleton S3 client via sync.Once, PG connection pool (25 open / 10 idle / 5-min lifetime).

Playwright RPA Service — Go · PostgreSQL
Automates Blinkit PartnersBiz hyperlocal scheduling — OTP-authenticated sessions, cookie/localStorage persistence, environment-driven CSS selector overrides. Migrated Socket.IO cluster adapter from redis-adapter (PSUBSCRIBE) to redis-streams-adapter for AWS ElastiCache Serverless.

AI Voice Agent — Python · Twilio · Google Cloud STT · Gemini · ElevenLabs
Async NDR re-attempt call pipeline with FFmpeg audio encoding, Prometheus metrics, and a no-action-taken guard preventing premature RTO classification.

Orchestr — React 19 · Express 5 · TypeScript · Prisma · MySQL · BullMQ
Full-stack e-commerce platform following the Saga pattern. Real-time Tally ERP sync via XML-over-HTTP. Razorpay payment gateway, Pino structured logging, admin dashboard.
