About me

Engineering products that solve real problems.

I enjoy turning ideas into reliable software—from API design and database modeling to real-time communication and retrieval-augmented AI.

I am a Computer Science undergraduate at Maharishi Markandeshwar University with hands-on experience building production backend systems and full-stack applications.

My work spans Socket.IO-based real-time workflows, scalable REST APIs, SaaS platforms and RAG systems that retrieve grounded answers from structured and unstructured knowledge sources.

Experience

Learning by shipping in production.

My internship experience strengthened my understanding of real-time systems, schema design, debugging and production ownership.

Key engineering impact

  • 01
    Replaced delayed HTTP polling with Socket.IO events

    Implemented real-time bell notifications for OPD token status updates across Node.js and Next.js clients, reducing notification latency from several seconds to near real-time.

  • 02
    Improved backend and data reliability

    Normalized the database schema and added soft-delete logic to preserve records while improving consistency in production workflows.

  • 03
    Debugged 15+ production API failures

    Used Postman and server logs to systematically reproduce and repair broken endpoints under a strict 48-hour deadline.

  • 04
    Worked across a live hospital token system

    Built an understanding of event-driven updates, API contracts, database relationships and reliability during peak operating hours.

Featured work

Products built end to end.

Selected projects that demonstrate full-stack development, event-driven workflows, AI integration and engineering depth.

ENGINEERING FOCUS

Backend Systems

Across projects and internship work, I design APIs, model relational and document data, integrate external services and debug failures end to end.

  • REST API design, validation and clean separation of concerns.
  • Real-time communication with Socket.IO and event-driven jobs.
  • SQL/NoSQL schema design, authentication and production debugging.
