Inbound Health, Remote Jun 2023 – Jan 2026

Senior Software Engineer .NET Core, DDD, React, AWS

● Led full-stack development of healthcare care-coordination workflows using ASP.NET Core 6, Domain-Driven Design

(DDD), REST APIs, delivering patient task and care-plan state management across multiple clinical programs.

● Extracted microservices from modular core for notifications, reminders, and integrations, implementing event-driven with RabbitMQ, AWS SQS, and AWS Lambda to reduce synchronous timeouts and workflow failures by 40%.

● Designed and evolved persistence with EF Core 6 and PostgreSQL to support high-frequency care-task and patient status updates, reducing request latency by 20% and stabilizing workflow execution during peak clinical activity.

● Built and maintained Angular 14 clinician and operations workflows, implementing form-heavy UIs, reactive forms, RxJS- based state handling, role-aware navigation, and error recovery, reducing user-reported workflow issues by 25%.

● Implemented security and data-handling controls using OAuth 2.0 / OIDC, JWT authentication, role-based authorization, encrypted secrets, and audit-friendly state changes, ensuring PHI access was traceable and compliant who changed patient state and why.

● Introduced gRPC for internal communication between the care-execution core and notification services in latency- sensitive paths, reducing serialization and network overhead in high-volume task assessment flows compared to REST.

● Applied performance tuning across APIs and background jobs (profiling, concurrency fixes, async/batching), and distributed tracking using OpenTelemetry, improving system stability and cutting production diagnosis time

● Built and hosted services on AWS (EC2, Lambda, RDS, S3, CloudWatch), provisioning infrastructure with Terraform to reduce production incidents tied to notification delays and workflow backlogs

● Enforced TDD and automated quality gates using xUnit, Moq, and SonarQube, increasing coverage for core workflows and reducing post-release defects in care-execution logic by 25%.

● Acted as technical lead for a medium-sized team, driving design reviews, delivery execution, and production readiness while remaining hands-on in complex features and incident resolution. Accent Technologies Inc, Melbourne, FL Dec 2018 – May 2023 Senior Software Engineer .NET Core, Django, Microservices, Angular, Azure Contributed as a senior individual contributor across multiple enterprise projects supporting partner onboarding, service provisioning, and billing integration, used by operations and partner teams to activate and manage contracted customers.

● Built and evolved Azure-hosted microservices using ASP.NET Core (2.1 6), implementing versioned REST APIs and clearly scoped services for partner configuration, provisioning requests, billing events, and reconciliation workflows.

● Implemented message-driven workflows with Azure Service Bus (queues/topics) to coordinate multi-step provisioning and billing processes across systems, reducing tight coupling between partner APIs and downstream billing engines.

● Designed and maintained Azure SQL databases, writing T-SQL for billing calculations, usage aggregation, reconciliation jobs, and SLA-driven reporting, supporting high-volume transactional and batch-oriented workloads.

● Supported both REST and SOAP integrations depending on partner maturity, maintaining legacy SOAP services while delivering REST APIs for newer integrations during phased modernization initiatives.

● Developed Angular 14 applications for operations and partner-support teams, using RxJS, reactive forms, role-based routing, shared component libraries, and API-driven state management to support complex, form-heavy workflows.

● Built Blazor (Server/WebAssembly) internal tools for administrative and support use cases, leveraging Kendo UI for Blazor (grids, forms, data editors, validation components) to rapidly deliver rich internal UIs without additional frontend stacks.

● Applied Entity Framework Core for CRUD-centric services while combining it with direct T-SQL execution for performance-critical billing and provisioning paths, balancing maintainability with throughput requirements.

● Implemented authentication and authorization using Azure Active Directory, OAuth 2.0, JWT, enforcing tenant-aware access, admin boundaries, and secure partner isolation across multiple applications.

● Used Datadog and Log Analytics to monitor API latency, message backlogs, integration failures, and provisioning delays, reducing time to diagnose partner-impacting issues.

● Contributed to CI/CD pipelines in Azure DevOps, supporting automated builds, test execution, and deployments for multiple services and web applications across environments.

● Worked within Scrum teams across different project streams, contributing to sprint planning, backlog refinement, estimation, and incremental delivery while supporting ongoing production operations and partner escalations. Medica, Minnetonka, MN Jun 2017 – Nov 2018

Software Engineer C#, ASP.NET, Angular, GIT

Worked on health insurance payer systems, supporting internal applications used for claims processing, member eligibility validation, and provider data management.

● Developed backend services using ASP.NET MVC and ASP.NET Web API (.NET Framework 4.6/4.7) within a layered architecture, implementing business rules tied to coverage, eligibility windows, and claim validation.

● Documented and validated internal APIs using Swagger (OpenAPI), improving API discoverability and alignment between backend services, QA, and consuming applications.

● Built and maintained WCF services used by internal systems to exchange member and provider data, supporting synchronous and batch-driven workflows across payer applications.

● Designed and maintained SQL Server databases, writing T-SQL for claims queries, eligibility checks, reporting extracts, and operational support tasks.

● Supported batch-oriented processing using SSIS and scheduled jobs to handle nightly eligibility updates, provider synchronization, and claims data reconciliation.

● Developed internal web interfaces using AngularJS and server-rendered views, supporting operations teams with form- driven workflows and administrative tools.

● Used Git for source control, collaborating through feature branches, pull requests, and code reviews as part of a team-based development workflow.

● Collaborated with business analysts, QA, and senior engineers to deliver incremental enhancements, bug fixes, and production support for core payer systems.

● Gained exposure to early cloud adoption efforts, supporting applications deployed in a hybrid on-prem / Azure environment, including configuration and deployment support. Bankers' Bank, Oklahoma, OK Jan 2014 – Jun 2017

Programmer

Contributed to enterprise banking systems supporting correspondent banking services for community banks, including transaction processing, settlement workflows, and internal reporting platforms.

● Developed and maintained SOA-based services using C#, ASP.NET, and WCF, orchestrating and consuming 10+ internal and external SOAP web services to support interbank data exchange and operational workflows.

● Implemented service-level validation, security checks, structured logging, error handling, and controlled multi-threading within WCF services, improving CPU utilization by 20%, and increasing system stability under concurrent workloads.

● Supported the incremental modernization of a legacy VB.NET monolithic system, refactoring core components into service-oriented modules using C#, ASP.NET, SQL Server, and message-based integration (RabbitMQ), achieving a 10% performance improvement without disrupting downstream systems.

● Built and tested SOAP integrations using SoapUI, validating request/response contracts, error scenarios, and edge cases for banking service consumers.

● Developed ASP.NET Web Forms and early ASP.NET MVC applications, implementing server-side validation and client-side validation patterns, and using Telerik UI controls to deliver data-dense internal banking dashboards

● Participated in the transition of internal desktop tooling (WPF) to ASP.NET MVC, supporting the first beta release of browser-based banking applications while maintaining functional parity with legacy systems.
