At Tech Almond Solutions Pvt Ltd, I own backend architecture and development across production applications, including a QR coupon platform that generates up to 1M encrypted serials per batch. I built its Worker Threads generation and Redis-backed scan resolution, with idempotent reward redemption and transactional wallet crediting.

I also built a shipping tracking microservice and a reusable gamification platform, and developed asynchronous processing pipelines with Redis, BullMQ, and AWS SQS. In personal projects, I built a WhatsApp messaging platform and an LLM-powered assessment platform using LangChain.
