.NET Software Engineer at Verstela

July 1, 2021 - Present

Adopted a test-first approach on the workforce scheduling platform from day one, establishing xUnit and Moq patterns and growing test coverage from near zero to 81% across billing and scheduling modules. Refactored a deeply coupled legacy scheduling service into clean domain-separated components, making it safe to modify without triggering cascading failures. Built ASP.NET Core REST APIs for multi-step scheduling and payroll workflows, with consistent error handling, validation middleware, and structured logging. Introduced Polly-based retry and circuit-breaker patterns for outbound service calls, eliminating transient failures. Implemented GitHub Actions CI/CD pipelines with xUnit tests and Docker-based deployment, ensuring no code with failing tests or quality violations reached production. Mentored two junior engineers on SOLID principles, dependency injection patterns, and writing xUnit tests that cover real business logic.

Established React Testing Library and Playwright test patterns on the work force portal, growing coverage from near zero to 80% across UI components and critical scheduling and payroll user flows. Refactored a class-based React component tree into functional hooks and React Query, making state management predictable and eliminating stale data bugs. Built accessible React components for scheduling and payroll workflows with WCAG 2.1 AA compliance, keyboard navigation, and screen reader compatibility applied consistently across all new UI. Introduced ESLint rules, Prettier, and Husky pre-commit hooks as team standards, keeping code review focused on logic and eliminating style inconsistencies. Built a Storybook component library for the platform design system, enabling visual regression testing and providing the design team with a live component reference alongside development.

Senior Frontend Engineer at Kyria Solutions

January 1, 2019 - June 1, 2021

Established React Testing Library coverage across clinical portal components, increasing coverage meaningfully and catching a date formatting error in the appointment scheduler before clinical UAT. Refactored the clinical data display component tree from class-based to functional hooks, eliminating lifecycle anti-patterns and making components safe to modify without side effects. Built accessible React UI for clinical scheduling workflows with WCAG 2.1 AA compliance, including keyboard navigation and ARIA labels applied consistently across patient-facing components. Introduced TypeScript strict mode and ESLint enforcement into the frontend CI pipeline, reducing runtime type errors and setting code quality standards for new feature branches. Applied clean component composition and separation of concerns across new clinical UI modules, ensuring new features followed patterns the whole team could navigate independently.
