At Pantelwar, I integrated Razorpay subscriptions and recurring auto-debit billing, including webhook-based payment verification and split-payment routing. I also developed email, push, and SMS workflows that achieved 99%+ delivery reliability and 3x lower send latency.
I built GoQueue, a Redis-backed task queue with worker pools, retries, dead-letter queues, and scheduled execution. At Pantelwar, I also improved application performance by ~40% through PostgreSQL query optimization, indexing, and Redis caching.
