Aliasgar Imdad Bootwala

PSP

• Contributed to the adapter layer and tenant mapping of a Payment Service Provider (PSP) platform, unifying 5 payment gateways behind one REST API; now live with 2 pilot clients in the Philippines and Vietnam. • Helped build a configuration-driven, MongoDB-backed payload-mapping system (chosen for schema flexibility), cutting new-gateway onboarding from custom code to a zero-code admin workflow and integration time from 3 days to 1. • Built the smart tenant-routing layer and backend authentication for the multi-tenant platform, helping cut regional deployment time from ∼1 day to 20–30 minutes. • Built a scheduled settlement-and-analytics cron job computing merchant payouts and transaction analytics across all 5 payment gateways. • Partnered on a Kafka-backed async transaction pipeline (50 msgs/batch), building the email-notification worker and Redis retry with dead-letter queues; 10–12 failed payments (incl. test accounts) were retried automatically. • Monitored production transactions with Grafana, Prometheus, and Loki; traced a cancelled transaction through correlation and request IDs in logs, identifying a Stripe limit rejection as the root cause.
