Dallas, TX, USA (Healthcare SaaS)

Mar 2024 – Present

•Architected and delivered a cloud-native patient scheduling and claims processing platform on ASP.NET Core 8 Minimal APIs and Angular 17, serving 250+ U.S. hospital clients and processing over 1.2 million API requests per day with 99.97% uptime.

•Engineered high-performance enterprise applications using C# 12 and ASP.NET Core 8, specializing in Minimal APIs and Web API for 250+ hospital clients.

•Architected and delivered 14 domain-driven microservices using Dapr and Ocelot API Gateway to improve system extensibility and deployment speed.

•Implemented FHIR R4-compliant RESTful APIs to enable real-time patient record exchange with Epic and Cerner EHR systems, cutting manual data reconciliation effort by 70% across participating hospital networks.

•Designed an Azure Cosmos DB-backed patient timeline service with partition-key-optimized queries, achieving single-digit millisecond read latency at 10,000+ concurrent users compared to 480ms on the prior SQL-based design.

•Built a Blazor Web Assembly admin portal with SignalR-based live dashboards, enabling operations teams to monitor appointment slot availability and claim statuses in real time, replacing an overnight batch report workflow.

•Established an Open Telemetry instrumentation baseline across all microservices feeding into Azure Application Insights and Grafana dashboards, reducing mean-time-to-detect (MTTD) incidents from ~45 minutes to under 8 minutes.

•Secured all service-to-service and client-facing endpoints using Azure AD B2C, OAuth 2.0 / OIDC, and RBAC claims, passing HIPAA security audit with zero critical findings; implemented OWASP Top 10 mitigations across API Gateway (Ocelot).

•Automated infrastructure provisioning using Terraform and Helm charts for AKS cluster deployments; set up GitHub Actions CI/CD pipelines with SonarQube quality gates, cutting post-deploy production defects by 52% year-over-year.

Pune, Maharashtra, India (Fintech / NBFC)

Jul 2021 – Apr 2023

•Developed core modules of a multi-tenant loan origination and lifecycle management system for four regional NBFC clients using ASP.NET Core 6 Web API and Angular 14, handling 15,000+ loan applications per month at peak.

•Redesigned the credit decisioning engine by integrating a rules-based workflow (MassTransit + RabbitMQ) to replace a synchronous processing bottleneck, improving throughput by 3x and eliminating application timeout complaints from operations staff.

•Migrated legacy ADO.NET data layer to Entity Framework Core 7 with Code-First migrations; restructured 340-table database schema down to 290 tables while maintaining full backward compatibility with all existing SSRS reports.

•Implemented Azure AD B2C-backed role-based access control (RBAC) with Claims-based authorization, deprecating a manual permission matrix that had caused 80+ production access-control bugs over the preceding 18 months.

•Integrated CIBIL and Experian credit bureau APIs into the eligibility assessment workflow using a resilient Polly-based retry and circuit-breaker pattern, reducing failed credit pull errors from 12% to under 0.8% of daily requests.

•Containerized four microservices using Docker and deployed to Azure App Service via Azure DevOps pipelines with blue-green deployment strategy, enabling zero-downtime releases for the first time in the project's history.

•Built Redis caching layer for frequently accessed loan product configurations and interest rate slabs, reducing average API response time on product listing endpoints from 320ms to 28ms and cutting SQL Server load by 40%.

•Created automated SSRS and Power BI Embedded reports for month-end loan disbursement, NPA tracking, and collection efficiency dashboards, saving the finance team 8+ hours of manual Excel consolidation per reporting cycle.
