My Experience @

Bajaj Finserv Health

Bajaj Finserv Health is a B2C platform that enables users to book lab tests, doctor appointments, and hospital slots—both online and offline. It also facilitates payments and allows users to interact with doctors/hospitals via chat or call.

I was part of the frontend development team, where I worked on refactoring, optimizing the code, and enhancing SEO. Later, I transitioned to the backend, contributing to core features like slot booking and the chat system, while improving performance and code quality. Through this experience, I honed my skills in writing efficient, clean, and maintainable code.

At Bajaj Finserv Health, I have...

Frontend Engineering

1. Built multiple reusable UI components to improve development speed and maintain design consistency across pages.

2. Spearheaded the migration from a monolithic frontend to a micro-frontend architecture, enabling independent development and deployments.

3. Designed and developed several user-facing pages from scratch, resulting in improved accessibility and user experience.

4. Implemented defensive CSS and responsive design strategies for a consistent UI across browsers and devices.

5. Enhanced SEO and Core Web Vitals, achieving over 85 scores on mobile and 95+ on desktop.

6. Integrated Strapi CMS for dynamic web content management, empowering non-engineering teams to publish updates without deployments.

7. Wrote clean, maintainable, and modular code while enforcing best practices and code readability.

Backend Engineering

1. Developed multiple backend microservices for booking, communication, and user management flows.

2. Migrated a core backend service from Express.js to NestJS, improving performance and maintainability.

3. Designed and implemented robust, well-documented REST APIs consumed across multiple product surfaces.

4. Integrated ELK stack dashboards for better observability and faster issue resolution, reducing average debug time per issue.

5. Optimized queries and schema design in MongoDB to improve data retrieval and reduce response times.

6. Developed efficient Redis-based caching strategies and Lua scripts to handle high-traffic workloads.

7. Built and scheduled cron jobs to automate recurring tasks such as sync operations and analytics updates.

System Design & DevOps

1. Gained extensive experience with Docker and Kubernetes for containerized deployments and workload orchestration.

2. Contributed to the setup and optimization of CI/CD pipelines, ensuring faster and more reliable releases.

3. Worked with the ELK stack and Kafka for logging, analytics, and event streaming.

4. Designed systems adhering to event-driven architecture principles to improve modularity and scalability.

5. Collaborated closely with infrastructure teams to ensure architectural alignment and platform stability.

Team & Process

1. Refactored legacy codebases to enhance performance and maintainability.

2. Advocated defensive coding practices and reviewed peer code to uphold team quality standards.

3. Actively contributed to technical discussions and architecture planning sessions for major releases.

4. Mentored junior developers and supported onboarding through pair programming and code walkthroughs.

5. Collaborated with product managers and design teams to translate business requirements into robust technical solutions.

6. Improved debugging workflows—evolved from console.log to using advanced debugging tools, though I still have a soft spot for console.log 😛.

7. Authored comprehensive test cases to ensure reliability, consistency, and regression safety.
