Banking and order integrations
Led order integrations with SBI, TCS, and ICICI for pharmacy order flows generating roughly Rs 3 Cr/month in revenue, coordinating across banking partners and internal payment infrastructure.
Technical decisions (one-way doors)
- SQS → Kafka for the B2B order aggregator — committed to streaming for throughput and replay; reversing would have meant re-proving latency and ordering guarantees.
- Cerberus as the vendor-facing gateway — centralized RBAC, rate limits, and observability for third parties instead of scattering policy across services.
Authorization and platform
Designed a Multi-Actor Authorization Engine for an agritech partner in Golang using OSO — implementing RBAC with fine-grained policy evaluation integrated directly into the auth service pod.
Built a high-throughput B2B Payment and Order Aggregator migrating from AWS SQS to Kafka — handling about 3,700 RPM at P99 ~3ms latency, improving reliability and throughput for downstream order processing.
Designed Multi-Tenant Identity & Order Fulfillment Services for an agritech platform (30K MAUs) using MERN + GraphQL, managing 13 services on Kubernetes.
Cerberus API gateway
Designed and built Cerberus — an API Gateway for third-party vendors — incorporating RBAC, rate-limiting, caching, event hooks, and dashboards.
Infrastructure and observability
Automated infrastructure provisioning with Terraform across environments; established full observability via CloudWatch and Grafana — reducing configuration drift and providing a single pane of glass for system health.
