Frontend Developer
RandomTrees
- Delivered end-to-end frontend development across multiple React.js web applications, building scalable user interfaces for internal tools and operational platforms in a production environment.
- Built reusable component libraries and standardized UI patterns across products, supporting frontend architecture improvements, reducing code duplication by 35% and speeding up frontend development.
- Integrated REST APIs and asynchronous data flows with retry logic, loading states, and error handling, improving application reliability, API performance, and user experience.
- Implemented JWT-based authentication and role-based access control to support secure, role-specific user journeys within a single, maintainable codebase.
- Partnered with data engineering teams to translate backend outputs into analytics dashboards and data visualization interfaces, improving decision-making visibility for business users.
- Improved application performance by 40% through code splitting, lazy loading, memorization, and targeted render optimization.
Frontend Developer Intern
RandomTrees
- Developed responsive React.js and Tailwind CSS components from Figma designs, contributing production-ready frontend code and reusable UI elements early in the internship.
- Supported feature delivery across frontend modules using component-based architecture, client-side state management, and REST API integration.
- Resolved defects and delivered sprint-based enhancements in an Agile environment, improving application stability and team execution.
Projects
AI-Proctored Exam Portal — Admin Dashboard & Candidate Portal
- The platform needed a secure way to conduct remote assessments and interviews while preserving exam integrity and providing visibility for administrators.
- Contributed to building the Admin Dashboard and Candidate Portal from scratch as part of a 2-member team, owning key frontend modules across both user journeys.
- Built real-time proctoring workflows with face-api.js and browser event tracking, integrated WebRTC-based interview flows, and implemented JWT-based authentication and role-specific routing for Admin and Candidate user interfaces.
- Delivered a production-ready assessment platform with Monaco Editor and analytics dashboards, reducing admin effort by 40% and increasing candidate completion rates by 25%.
Enterprise Resource Tracker Dashboard
- The organization lacked real-time visibility into resource allocation — bench strength, billable vs. non-billable hours, and upcoming conflicts were tracked manually across spreadsheets.
- Led frontend architecture and delivery for the resource management platform, assigning module ownership and driving implementation with one additional developer.
- Led frontend development for CRUD workflows covering employees, projects, clients, and allocations. Directed OAuth2 API integration with retry and backoff logic to automate employee data sync, implemented Azure MSAL single sign-on with JWT fallback, and centralized client-side state management in Zustand.
- Delivered a live enterprise dashboard that eliminated manual data-entry overhead, reduced UI state inconsistencies by 30%, and gave the organization real-time visibility into bench and project allocations.
CRM Tracker Platform
- Developing a responsive enterprise CRM platform for managing recruitment requests, candidate profiles, user administration, dashboards, and business workflows.
- Built reusable React components, dashboard widgets, advanced search, filtering, modal workflows, and role-based navigation to improve maintainability.
- Designed modular frontend architecture using Context API, custom Hooks, shared layouts, and reusable components, making the application scalable and easier to extend.
- Integrated interactive analytics dashboards using Recharts and optimized routing with React Router for a seamless user experience.
- Collaborating with cross-functional teams to deliver production-ready CRM features in an Agile development environment.
AI-Proctored Exam Portal
- Built a real-time AI-powered proctoring engine using face-api.js to monitor face detection, eye movement, and browser activity.
- Integrated WebRTC interview rooms with secure JWT authentication, device selection, reconnection handling, and role- based routing.
- Implemented trust-score batching every five seconds for continuous candidate monitoring.
- Reduced administrative effort by 40% while improving candidate completion rates by 25%.
