Production Experience

Software Development Engineer Intern

Podbook|Nov 2025 — Jan 2026

During my time at Podbook, I focused heavily on backend scalability and integrating AI pipelines into the core product.

The primary technical achievement was building a hybrid RAG pipeline for LLM-powered features and heavily optimizing the user onboarding flow. By decoupling notification services into an asynchronous Redis Queue pipeline, I brought the critical path latency down by 97%.

  • ▹Architected a scalable backend using FastAPI and PostgreSQL, Built a RAG pipeline integrating BM25 and FAISS vector search with sentence-transformer embeddings, to improve context retrieval precision for LLM-powered features.
  • ▹Created a non-blocking email pipeline via Redis Queue (RQ) to decouple notification services from the authentication flow, slashing user signup latency by 97% (from 4s to 100ms).

Backend Developer Intern

Airtel Digital|Jun 2025 — Sep 2025

At Airtel Digital, the core challenge was scaling the backend to handle massive user loads without blocking primary business transactions.

By implementing an event-driven Kafka architecture, I successfully decoupled the analytics pipeline from the core logic. Additionally, building a custom in-memory QuadTree for spatial queries drastically improved location lookup performance.

  • ▹Developed high-throughput microservices using Spring Boot, designing a custom in-memory QuadTree data structure to optimize spatial queries, reducing location lookup complexity from O(N) to O(log N).
  • ▹Accelerated continuous integration and continuous deployment cycles by 60% through Docker containerization and reduced average query latency by 200ms by implementing a Redis caching strategy for frequently accessed data.
  • ▹Designed an event-driven architecture using Apache Kafka to asynchronously process user events and generate advanced metrics in real-time, decoupling analytics generation from core business logic to ensure high availability.
