• Built and deployed containerized microservices on Microsoft Azure with Docker, integrating Azure DevOps CI/CD for automated builds, testing, and releases; prioritized scalability, reliability, and secure deployments.

• Designed and shipped production-grade RESTful services and features using C#, ASP.NET Core Web API, EF Core, SQL, and Angular, following enterprise engineering standards and secure coding practices.

• Applied Clean Architecture, SOLID, and testable design; authored unit and integration tests to improve code quality, maintainability, and regression coverage in agile sprints.

• Optimized data access and service performance (query tuning, efficient data structures, asynchronous I/O) to enhance throughput and reduce latency in distributed components.

• Collaborated with senior engineers in design reviews and code reviews; refined requirements, produced technical designs, and delivered features with a customer-obsessed mindset in Scrum-based iterations.

• Improved observability via structured logging and metrics; triaged issues and performed root-cause analysis to drive reliability and operational excellence.

• Designed and implemented scalable backend services in .NET Core to handle train search, seat allocation, ticket booking, and cancellation flows with real-time data consistency.

• Built a robust payment pipeline with Razorpay, including order creation, signature validation, retry logic, and secure refund handling with proper failure management.

• Developed a rule-based cancellation and refund engine, enforcing eligibility checks, refund slabs, and automated Razorpay-driven refund execution.

• Implemented backend-driven communication workflows using NodeMailer for booking confirmations, cancellations, and refund updates.

• Added comprehensive unit tests for business logic, payment flows, and refund rules, improving reliability and preventing regressions.

• Built and maintained the platform’s backend, designing an optimized PostgreSQL schema using Prisma Accelerate to ensure predictable performance and fast queries.

• Deployed compute-intensive logic to Cloudflare Workers, reducing backend load and improving responsiveness by ~30%.

• Created and published a custom Zod-based npm validation package, enforcing strict backend data schemas and eliminating client–server mismatches.

Conducted in-depth research on alternative energy sources for Electric Vehicles (EV) and authored a research paper titled "Exploring Sustainable Alternatives for Electric Vehicles", which was successfully published in IC-HSTE 2022.
