I’ve built full-stack systems at Ideal Tech Labs, spanning NestJS/Apache Kafka microservices and MEAN stack features for card enrollment and real-time event streaming for 30,000+ active users.

I worked on PCI-DSS compliant transaction pipelines with end-to-end encryption integrating Visa APIs (100,000+ transactions monthly), plus multi-tenant card management secured with OAuth 2.0 and rate limiting via Gravitee API Gateway.

On the frontend, I’ve shipped Angular 17 modules tied to resource, timesheet, and workforce management for 200+ users—then paired it with Node.js/Express.js APIs to improve platform performance by 25%.

I also handle risky data changes: I executed 700,000+ record migrations with zero data loss and under 1-hour downtime, and I’ve supported production incidents with Datadog and Grafana while keeping 99.9% SLA compliance.
