Experience
AI-driven Healthcare Platform
The platform helps detect cancer at early stages, enables doctors to manage personalized care plans, and automates follow-up workflows for patients. I also optimized PostgreSQL performance, redesigned the audit logging infrastructure using OpenSearch, and built scalable AWS services using SQS, SNS, Pinpoint, EC2, and S3 to reliably support high-volume clinical operations.
Lumoscore – A Web3 Multi-chain Asset Platform
The platform supports token creation, transfers, swaps, and real-time asset analytics while maintaining high availability and performance. I also optimized blockchain data synchronization workflows and designed the system to support future multi-chain expansion with minimal architectural changes.
Aviation Safety Management Platform
Built and enhanced core aviation safety workflows, including FRAT, MRAT, ORAT, hazard and safety reports, bulletins, policy acknowledgments, dashboards, and role-based access for operators, safety teams, pilots, technicians, and executives. Designed and restructured the application architecture, database, Supabase back end, authentication/authorization model, tenant-aware data access, and front-end workflows.
Established staging and production environments, implemented security and deployment improvements, and successfully deployed the platform to production. Also built companion iOS and Android apps and managed their production releases, successfully publishing both on the Apple App Store and Google Play Store.
