Work experience

Software Engineer at Tata Consultancy Services, Jul 2023 - Present · 2 yrs 11 mos, Hyderabad, 🚀 Key Contributions: 🔹 NielsenIQ: Worked on a reporting tool that lets analysts build slide decks with live charts. My job was the full pipeline - from the Angular UI all the way to a Node.js layer that turned raw data into chart-ready JSON. 🔹 The chart-to-slide insertion used to take around 10 seconds per visual. After moving to a headless Highcharts image generation flow, it dropped to under 3s - a 70% improvement. 🔹 Built and optimized the REST API endpoints that served analytics data. Cut response payload size by 40% by cleaning up what the server was sending and how it was structured. 🔹 Added real-time sync for slide titles and annotations across the app - so when one analyst updates something, others see it instantly. This cut report creation time by about 25%. 🔹 Migrated the app from older Angular patterns to Angular v17 with Signals for state management. Server load dropped by roughly 30% because we stopped running unnecessary change detection cycles on a system handling 50+ updates per session. 🌐 Other Clients: 🔸 Google Developer Programs: Improved UX, accessibility, and Dark Mode compliance on developers.google.com within the Google3 monorepo. Reduced bug resolution time by 30% through efficient change management. 🔸 GE Healthcare: Migrated master data management apps from GE Corp. to GE Healthcare, developing Angular-based validation components supporting 5,000+ users and achieving 95% unit test coverage with Jasmine and Karma. 💡 Impact: Strengthened front-end architecture and enhanced UI performance across multiple client products, delivering fast, responsive, and maintainable solutions.

Associate at Cognizant, Jan 2023 - Jun 2023 · 6 mos, India, → Built the member onboarding portal for Kaiser Permanente an Angular v14 application with personalized registration flows integrated with secure backend identity services. → Integrated OAuth 2.0 and JWT-based authentication on the frontend, ensuring a seamless user login experience while maintaining strong backend security standards. → Contributed to the Federated SSO system by developing API consumers that enabled sign-in across multiple healthcare services, supporting over 200,000 members. → Helped build the Health Class Booking feature - designing the API layer, implementing slot concurrency logic, and defining MongoDB schemas to manage schedules and user bookings. → Optimized the booking API to handle peak registration traffic efficiently, reducing latency during high-demand windows by approximately 25%.

Programmer Analyst at Cognizant, Jan 2021 - Dec 2022 · 2 yrs, Hyderabad, → Built and maintained Angular-based frontend applications for healthcare clients, primarily working on member-facing portals including registration flows, dashboards, and booking interfaces. → Took ownership of cross-browser compatibility for the applications I handled, consistently achieving 99% compatibility across Chrome, Firefox, Safari, and Edge. → Collaborated closely with QA and backend teams to identify and resolve issues before production release, significantly reducing production bugs through improved pre-release testing practices. → Began leading small feature implementations - writing cleaner, more reusable Angular components and supporting junior teammates when they encountered blockers. → Worked in an Agile environment with regular sprints, stand-ups, and code reviews, while using Azure DevOps for task management and deployment coordination.

Programmer Analyst Trainee at Cognizant, Dec 2020 - Dec 2021 · 1 yr 1 mo, India, → This is where I started professionally. Spent the first several months getting trained on Angular, JavaScript, Node.js, and MongoDB - then gradually moved into real project work. → Contributed to frontend modules writing Angular components, wiring up APIs, fixing bugs, and learning how production code is actually structured in a large team. → Picked up SCSS, Git workflows, and unit testing with Jasmine and Karma early on. These became habits I carried into every role after. → Got my first exposure to Node.js and MongoDB here - which eventually became a core part of my full stack skill set.
