EXPERIENCE

Senior React Developer

Trinetix, Inc.

03/2022 - 06/2025 Remote

Architected and implemented scalable, reusable React components using advanced hooks (useState, useEffect, useMemo, useCallback, and custom hooks) for diverse client projects in fintech, healthcare, and e- commerce.

Led complex state management using Redux Toolkit with slice-based architecture, leveraging RTK Query for efficient API caching, data fetching, and synchronization with minimal boilerplate. Applied React Context API strategically to manage global app concerns such as theming, localization, and authentication, significantly reducing prop drilling and improving code clarity.

Delivered high-performance user experiences through code-splitting, lazy loading with React.lazy and Suspense, memoization (React.memo), and virtualization techniques on data-heavy dashboards. Drove migration from legacy class components and Redux Thunk to modern React functional components and Redux Toolkit, improving maintainability, testing, and developer velocity.

Created custom hooks encapsulating complex business logic and side effects, enhancing code reuse and testability across multiple enterprise- grade applications.

Championed testing with React Testing Library and Jest, building comprehensive unit and integration test suites that increased code reliability and reduced production defects.

Collaborated closely with backend teams to design and consume RESTful and GraphQL APIs using RTK Query and Apollo Client, ensuring seamless, secure data flow.

React Developer

UKG

04/2017 - 02/2022 Weston, FL

Led the modernization of legacy HR and payroll platforms by migrating large AngularJS and jQuery codebases to React, leveraging advanced React hooks and functional component architecture for maintainability and performance.

Designed and implemented normalized global state management using Redux Toolkit (createSlice, createEntityAdapter) and RTK Query, enabling predictable state updates and efficient server data caching. Developed reusable custom hooks and higher-order components

(HOCs) to abstract complex business logic and side effects, reducing duplication and improving consistency across applications. Built and maintained a scalable, accessible design system of atomic components, ensuring UI consistency and accelerating feature development across cross-functional teams.

Integrated React frontends with optimized Java Spring Boot REST APIs and GraphQL endpoints via RTK Query and Apollo Client, supporting advanced features like pagination and optimistic UI updates. Championed frontend testing using React Testing Library and Jest, authoring unit, integration, and snapshot tests to uphold code quality and prevent regressions.

Mentored junior engineers on modern React best practices, hooks patterns, performance optimizations, and debugging strategies. Implemented performance optimizations including code-splitting, memoization, and virtualization to maintain responsive, fast user interfaces.

Engaged actively in Agile ceremonies including sprint planning, design reviews, and retrospectives, advocating for clean code and continuous refactoring.

SUMMARY

I bring 12+ years of hands-on experience building

robust, scalable React applications, starting from the framework’s early days through mastering

modern hooks, Redux Toolkit, Context API, and

client-side templating tools like Mustache and

Handlebars. I specialize in crafting clean,

maintainable, and high-performance frontends

that both development teams trust and end-users

love.

Prior to React, I built a strong foundation in C++ for more than 7 years, which ingrained in me the

discipline to write efficient, clean, and reliable code. This deep engineering mindset guides my

approach to both frontend and backend

development.

On the backend, I’m skilled with Node.js (MERN

stack), Java J2EE (Spring Boot), and MongoDB.

I’ve architected and maintained RESTful APIs,

implemented secure OAuth2 and JWT

authentication flows, and deployed applications

on enterprise platforms like Red Hat OpenShift.

My full-stack experience enables me to

seamlessly integrate frontend and backend

systems to deliver end-to-end solutions.

As a proud U.S. citizen, I’m fully authorized to

work and collaborate across distributed Agile

teams. I thrive in fast-paced environments,

leveraging Git for version control, unit testing

frameworks for code quality, and advanced

debugging tools daily. I’m ready to hit the ground running and drive impactful, high-quality software delivery.

EXPERIENCE

Frontend Developer (Early React Adopter)

Magic Leap

06/2013 - 03/2017 Plantation, FL

Pioneered early adoption and evangelism of React (starting with v0.14), architecting component-based UI systems that replaced legacy jQuery workflows with declarative, maintainable React components. Designed and developed complex, interactive dashboards and QA tooling leveraging React integrated with D3.js for dynamic data visualization, showcasing mastery of React’s rendering lifecycle and state management.

Built scalable, reusable React component libraries following atomic design principles, enhancing UI consistency and accelerating cross- team feature development.

Implemented client-side routing with React Router and managed application state with React Context API, setting the foundation for state management patterns before Redux adoption.

Optimized React app performance using code-splitting with React.lazy and Suspense, memoization strategies (React.memo, useMemo), and avoided unnecessary re-renders with careful hook usage. Collaborated closely with backend .NET teams to integrate asynchronous data flows and real-time WebSocket events into React components, ensuring smooth, reactive UI updates.

Led React-focused code reviews and knowledge sharing sessions, mentoring teammates on hooks patterns, performance tuning, and testing with Jest and Enzyme.

Developed comprehensive unit and integration tests for React components, improving reliability and maintainability of complex UI systems.

Software Engineer (C++ and Frontend)

Ultimate Software(now UKG)

05/2005 - 05/2013 Weston, FL

While primarily focused on backend C++ systems, contributed significantly to frontend efforts by developing dynamic user interfaces with JavaScript, jQuery, HTML5, and CSS3, bridging legacy UI tech with emerging React paradigms.

Partnered with UX and backend teams to prototype and deliver React- based widgets and UI enhancements that improved employee self- service portals’ responsiveness and interactivity. Applied deep understanding of component lifecycle and event handling to transition portions of the legacy frontend toward modern, declarative UI frameworks.

Developed reusable JavaScript modules and custom event handlers as precursors to React hooks, laying groundwork for later React adoption within the team.

Collaborated in Agile environments, emphasizing code quality through peer reviews, automated testing, and iterative UI improvements. EDUCATION
