Experience
Senior Software Engineer
CitiusTech · Dec 2024 – Present
- Architected event-driven claim-processing microservices (Azure Functions, Service Bus, Durable Functions, Cosmos DB) for high-volume healthcare payer workloads, using the outbox pattern with idempotent consumers for reliable, effectively-once delivery; reduced P99 latency from 4.2s to 1.1s.
- Built an AI-powered claim-validation pipeline (Azure AI Document Intelligence + RAG with citation-grounded verification) to extract and verify claim data while preserving HIPAA-compliant audit trails.
- Developed claim-management applications end to end - Angular 18+ / TypeScript front end (TPA Reimbursement, Pricing Analyzer, Chargemaster screens) over a .NET Core REST API - owning the full path from API contract to UI and reducing cross-team handoff.
- Designed CI/CD with automated regression gates (NUnit, integration tests) and observability (structured logging, OpenTelemetry); pre-deploy validation caught issues before they reached production.
- Engineered Elasticsearch-backed claim search across multi-tenant payer systems, enabling fast claim lookup and analytics at scale.
- Led migration from a monolithic .NET Framework application to cloud-native .NET Core microservices, reducing infrastructure cost through function autoscaling and removing resource-allocation bottlenecks.

Software Engineer
Caredata Informatics · Mar 2021 – Dec 2024
- Designed and shipped 25+ full-stack features (clinical + billing modules) using .NET Core, ASP.NET Core MVC, Angular, and EF Core; improved module time-to-insight through query optimization and caching (Redis, in-memory).
- Integrated 10+ mission-critical third-party systems (HIMS, LIMS, HL7 over Mirth Connect, REST/ODBC) for clinical data exchange - reconciling inconsistent HL7 message versions across vendors without breaking downstream consumers, and significantly reducing manual data-entry errors through automated validation and dual-write consistency.
- Replaced manual lab data-entry workflows with device drivers for Windows-based lab-analyzer connectivity; cut data-entry turnaround from 45 min to 2 min per batch (40+ batches/day).
- Built 15+ scheduled reports (DevExpress, SSRS, C# stored procedures) replacing manual weekly analysis, giving 50+ hospital staff real-time dashboard access.
- Profiled and optimized application performance (dotTrace, SQL query analysis); reduced page load time 45% (8.2s → 4.5s) and improved concurrent-user capacity on the same infrastructure.
