PROFESSIONAL EXPERIENCE
.NET Software Developer (Mid-Level) / Scrum Master Jan 2025 – Present
DataArt
Secure medical platform managing patient data, automated document processing, and integrations with external healthcare
providers. Owned backend integration work end to end — ML service integration, REST contract design, and Angular front-
end support.
• Designed and built integration modules from the ground up, including REST API contracts for data exchange with
external healthcare providers and automated pipelines extracting structured data from unstructured medical
documents.
• Integrated NLP capabilities for parsing clinical notes and patient records, enabling automated classification of medical
documents and intelligent data routing.
• Reduced transient integration failures from ~15/day to near zero by implementing a retry mechanism for external calls
and resolving concurrency issues around incremented counters.
• Developed and maintained backend services in C#/.NET and ASP.NET Core Web API; extended existing service methods
with backwards-compatible changes to protect downstream consumers.
• Built reusable Angular components for document upload workflows and implemented real-time status tracking via
SignalR for long-running processing tasks.
• Provisioned integration infrastructure with Terraform — API gateways, networking resources, and external service
connections — ensuring consistent, reproducible environments across dev/test/prod.
• Eliminated regression escapes from “minor” fixes by tightening the pre-release QA process: regression testing on the
test environment became mandatory for every story before merging to the release branch.
• Ran Scrum Master activities: facilitated daily stand-ups and sprint planning, maintained Jira/Confluence documentation,
and coordinated priorities and task distribution.
Junior .NET Software Developer Sep 2022 – Nov 2024
DataArt
Scalable financial platform for currency exchange, processing ~500k transactions/day in real time with integrations to
external financial services.
• Developed and supported integration modules for communication with third-party financial services on a platform
handling ~500k transactions/day.
• Implemented new backend endpoints and maintained API functionality in C#/.NET and ASP.NET Core Web API.
• Refactored legacy areas and resolved defects to stabilize core transaction flows and improve data consistency.
• Participated in release preparation and CI workflows; troubleshot issues identified during customer testing.
• Prepared technical documentation and collaborated with the team on requirements clarification.
INTERNSHIP
C# Developer Intern Apr 2022 – Jun 2022
SoftServe
Inventory management system: a WPF desktop application tracking stock levels across multiple warehouse locations, with
real-time updates, reporting, and notifications.
• Built UI and functionality with WPF and MVVM (XAML, custom controls, data binding).
• Transitioned to a web-focused track: contributed to a web application using ASP.NET MVC, ASP.NET Core Web API, and
Angular.
• Containerized .NET services with Docker; worked with basic Kubernetes manifests (Deployment/Service) and log
troubleshooting.
