Senior Full-Stack Engineer at Verstela

July 1, 2021 - Present

Built Jest backend and React Testing Library frontend test patterns on the work force platform, growing coverage from near zero to 82% across API handlers and scheduling UI components. Refactored a deeply nested Express.js service layer into a clean handler/service/repo pattern, making the backend safe to modify without breaking interconnected scheduling and payroll logic. Built Node.js REST and GraphQL API endpoints for scheduling workflows with Zod validation, structured logging, and consistent error handling across all new API surfaces. Introduced ESLint strict rules, Prettier formatting, and Husky pre-commit hooks as team standards, eliminating style inconsistencies and keeping code review focus on logic. Built GitHub Actions pipelines with Jest coverage gates, TypeScript strict checks, and Docker deployment, ensuring no code with failing tests or type violations reached production. Used GitHub Copilot daily for Jest test generation and React component refactoring assistance, apply

Led the establishment of React Testing Library coverage across the work portal, growing UI test coverage from near zero to 80% across UI components and critical scheduling and payroll workflows. Refactored a class-based React component tree into functional hooks and React Query, making state management predictable and eliminating stale data bugs that had caused ticket complaints. Built accessible React components for scheduling and payroll workflows with WCAG 2.1 AA compliance, keyboard navigation, and screen reader compatibility across all new UI. Introduced ESLint strict rules, Prettier, and Husky pre-commit hooks as standard tooling, keeping code reviews focused on logic and eliminating style inconsistencies from pull requests. Created a Storybook component library for the platform design system, enabling visual regression testing and giving the design team a living component reference alongside development.

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.
