What I'm looking for

I'm looking to lead and build scalable backend or full-stack systems, especially event-driven platforms involving healthcare, payments, real-time processing, and production-scale architecture.

I'm leading backend architecture at Mokaa Studios for a photo booth campaign platform that processes high volumes of images in real time. I architected an event-driven pipeline using Kafka, SQS, Lambda, and S3, and introduced AI-based image workflows for live campaigns.

At GivHealth Care, I owned HIPAA-compliant backend services supporting HL7 and FHIR medical-data exchange. I improved API response times by 45%, led backend delivery and CI/CD decisions, and helped services sustain 3x flu-season peak load at 99.95% uptime.

Over six years at AlgoMedical Group, I grew from junior to senior backend developer and owned API design and cross-service integration. I built retry-safe payment processing across five gateways, increased test coverage to 85%, and supported 10,000+ concurrent users.
