Software Development Engineer - I at Aditya Birla Capital

June 1, 2023 - August 1, 2025

Architected a multi-channel communication platform on AWS API Gateway + Lambda (Node.js) delivering WhatsApp/SMS/Email across user journeys; added async queues, retries, DLQs, idempotency keys, correlation IDs, and rate limiting to sustain 10M+ messages/day and reduce delivery time by 42.43%. Led BizTalk → AWS re-platforming, remapping 8+ services, exposing 5 API Gateway endpoints, and decomposing workflows into 12 Lambdas, increasing availability to 99.9% and cutting ops overhead by 60%. Re-modeled user data from on-prem MySQL to DynamoDB with PK/SK design, GSIs, and conditional writes; read latency decreased by 36%. Implemented a read-through cache in DynamoDB with daily Step Functions batch refresh to reduce holdings API response time from 2.8s to 350ms. Developed a ShortURL API and a bulk short-link service with TTL expiry for KYC/payments processing up to 12M links. Engineered a token store + cache layer to minimize redundant upstream token calls by 79% and avoid cross-team cont
