At Flash, I own bill-payment and transaction domains across six payment gateways, supporting more than 50 bill payment services. I built automated stuck-payment recovery that reconciles late callbacks and reduced recovery time from up to 12 hours to under 6 minutes.
I led the design and development of Flash Wallet for top-ups and payouts to mobile wallets and bank accounts. I also led the Dsquares integration and introduced distributed tracing and trace/log correlation across payment services with OpenTelemetry and SigNoz on Kubernetes.
At GoPlace and AtenTEC, I developed production backend services and microservices using Go and NestJS, including cloud-native services on Google Cloud. My work has included modularizing services, designing data models, and building unit and integration tests.
