Deliver enterprise logistics and compliance applications for a global technology client. Develop and maintain responsive web applications in ReactJS, building reusable component architectures and managing application state with Redux and the Context API. Integrate React interfaces with RESTful APIs, handling asynchronous request flows, loading and error states, and resilient failure handling across enterprise workflows. Apply TypeScript throughout the React codebase for typed component contracts and safer refactoring, and cover functionality with unit and end-to-end tests. Participate in code reviews with constructive feedback, debug and resolve defects in existing applications, and contribute to improving team development processes and standards. Designed and implemented the complete Carta Porte workflow for Mexican customs compliance, including multi-step validation and state handling for cargo operations under continuously evolving SAT regulations. Adopted Gemini as a core part of the daily development workflow — generating and refactoring production code, authoring unit and E2E tests, investigating defects, and reviewing changes — validating all output against project standards rather than accepting it as-is. Extended and adjusted existing Node.js REST endpoints to support new frontend workflows, coordinating API contract changes and payload validation with backend teams. Built and automated CI/CD pipelines with Google Cloud Build, managing per-environment configuration and release promotion, and deployed highly available applications via Firebase Hosting and Google Cloud Storage. Leveraged Angular Signals to build highly reactive, optimized logistics workflows, actively managing framework upgrades from Angular 17 through 21. Architected automated monitoring workflows simulating user interactions to proactively detect security vulnerabilities and preempt application failures. Modernized legacy JavaScript test suites to TypeScript strict-mode standards, refactoring hundreds of test files with JSDoc best practices.

Developed and maintained enterprise management applications, driving continuous framework modernization across Angular 14, 15, and 16, utilizing RxJS for complex asynchronous data streams. Configured and managed production deployments on AWS S3 and CloudFront, streamlining release cycles through AWS CodePipeline and handling cache invalidation and versioned rollouts to enable safe rollbacks. Maintained and extended Node.js service endpoints consumed by the frontend, adjusting request/response contracts and validation to support new product features. Implemented scalable frontend enhancements leveraging strictly Typed Reactive Forms for robust data validation. Guided team members on frontend best practices and maintainable architecture patterns, including enterprise state management with NgRx.

Developed React features for a fintech vehicle credit platform, implementing advanced state management solutions using Redux and the Context API. Integrated React frontends with AWS cloud-native services, utilizing AWS Cognito for secure authentication and consuming serverless APIs via AWS API Gateway. Optimized frontend performance by applying lazy loading, useCallback, useMemo, and React.memo to minimize unnecessary re-renders. Managed complex component lifecycles and side effects utilizing React Hooks, and enhanced application stability by integrating Error Boundaries for resilient error handling. Mentored new developers and collaborated on frontend architecture and technical planning initiatives.

Delivered enterprise frontend solutions for travel, hospitality, insurance, and telecom clients. Spearheaded the architectural migration from legacy AngularJS 1.x to modern Angular, executing progressive version upgrades through Angular 2, 4, 6, and 8. Facilitated CI/CD workflows using Azure DevOps and leveraged AWS S3 and CloudFront for distributed asset hosting, automating build and release steps across client environments. Adjusted and debugged Node.js API endpoints supporting customer-facing features, working alongside backend teams on integration and data-shape issues. Developed scalable Angular applications and customer-facing features, implementing lazy loading modules to significantly reduce initial bundle sizes. Supported production issues, debugging, and rapid defect resolution in high-traffic environments.

Led migration of a legacy Windows Mobile retail application to Android using Java, managing development, testing, and deployment as the primary developer.

Developed WordPress, Joomla, and static websites using JavaScript, PHP, HTML, and CSS.

Developed internal applications using Java and Spring MVC technologies.

Built responsive websites and WordPress solutions for multiple clients.
