Modernized legacy Angular modules (v12 v18) refactoring deprecated APIs restructuring RxJS data flows and resolving breaking dependency upgrades reducing regression defects by 30% and improving release stability across enterprise deployments. Built large-scale enterprise features originally using Angular 12 designing modular feature-based architecture and shared component libraries capable of supporting complex multi-step workflows with high concurrency and large data sets. Developed React-based feature modules and UI components for specific dashboard and reporting interfaces ensuring consistency in state management and API integration alongside Angular systems. Implemented advanced NgRx state management patterns including action-driven side effects memorized selectors and structured reducers to maintain consistent application state across concurrent API interactions. Designed and implemented RESTful APIs using Node.js and Express structuring route handlers service layers and middleware pipelines to enforce separation of concerns and enable maintainable backend growth. Built centralized request validation and structured error-handling middleware ensuring standardized API responses and improving production observability during incident investigations. Designed MongoDB schemas aligned with readwrite access patterns and implemented compound indexing strategies reducing average query latency by 40% and improving throughput under concurrent transactional workloads. Developed advanced MongoDB aggregation pipelines for real-time operational dashboards reducing backend response time by 30% and decreasing frontend computation overhead for reporting-heavy views. Deployed serverless backend logic on GCP leveraging Cloud Functions with HTTP triggers for lightweight API endpoints and event-driven processing while using Cloud Run for containerized Node.js services requiring scalable runtime environments. Integrated multi-cloud storage and serverless workflows across GCP and AWS leveraging FirebaseCloud Storage and S3 for secure asset management Lambda and API Gateway for scalable endpoints and CloudFront for optimized global asset delivery within distributed application environments. Built WebSocket-based real-time update mechanisms for live workflow tracking significantly improving operational visibility and user responsiveness. Wrote comprehensive unit tests for Angular components NgRx effects and backend services using Jest and developed Cypress end-to-end suites validating high-impact production workflows. Collaborated closely with UIUX designers to translate wireframes and Figma prototypes into accessible responsive interfaces refining interaction flows and improving usability across enterprise dashboards. Conducted code reviews and mentored junior engineers on Angular upgrade strategies backend API design patterns MongoDB query optimization and effective testing methodologies.

Senior Full Stack Developer / January, 2016 — March, 2021

Developed enterprise Angular applications using Angular 6 and 7 building modular UI components and feature modules supporting operational dashboards and internal business systems with complex data flows. Modernized Angular (2+) application architecture including upgrade to Angular 8 refactoring tightly coupled services improving dependency injection structure and restructuring RxJS-based reactive data flows to enhance maintainability and stability. Developed React-based dashboard modules and reusable UI components for reporting interfaces integrating REST APIs and maintaining consistent state synchronization across user sessions. Implemented advanced RxJS chaining strategies to manage dependent API requests and asynchronous UI updates in reporting-heavy environments. Designed and developed RESTful APIs using Node.js and Express implementing structured routing middleware validation layers and service-level abstraction for scalable backend expansion. Deployed serverless backend services on AWS (Lambda API Gateway S3) improving API scalability during peak reporting cycles and reducing infrastructure maintenance overhead by 20%. Managed MongoDB Atlas deployments for cloud-hosted database environments creating indexing strategies and aggregation pipelines to support reporting-heavy use cases. Implemented authentication middleware and structured request validation to standardize backend behavior and improve error traceability.

Angular Developer / May, 2011 — November, 2015

Developed AngularJS-based SPAs for form-intensive enterprise workflows structuring controllers and services to separate UI presentation from business logic. Built responsive UI components using HTML5 CSS3 and Bootstrap to ensure cross-browser compatibility and consistent user experience. Integrated REST APIs and implemented structured client-side validation and error handling. Supported application hosting across AWS and Azure environments assisting with Azure App Service deployments and Blob Storage integrations. Participated in debugging runtime issues and collaborating with backend teams to resolve API-related defects in production. Contributed to peer code reviews and unit testing efforts to improve frontend stability and maintainability.
