Tools and Technology
Work Experience
Backend Engineering Intern · Exanor
April 2026 — July 2026- Engineered core CMS backend microservices using TypeScript and PostgreSQL, architecting relational schemas and indexing strategies for a scalable multi-author blog platform.
- Collaborated on system architecture for a globally scalable commerce engine, implementing reliable transactional workflows and real-time inventory synchronization APIs.
- Maintained code quality through cross-functional design reviews, API contract validation, and integration testing.
Vecta
GitHub- Architected a multi-tenant workspace engine in PostgreSQL using Prisma 7, enforcing strict tenant isolation, cascading data integrity, and audit logging.
- Eliminated polling by building an event-driven WebSocket microservice with in-memory channel routing and heartbeat monitoring for sub-15ms peer-state dissemination.
- Secured sessions and prevented database spikes using an atomic sliding-window rate limiter in Redis with 120s TTLs and SHA-256 token hashing.
Atlas
GitHub- Engineered a production-grade RAG platform using Llama-3 and open-source embeddings, featuring an agentic LangGraph loop with automated self-correction and query rewriting.
- Implemented hybrid retrieval combining BM25 and dense vector search with cross-encoder reranking, supported by an asynchronous FastAPI, Qdrant, and PostgreSQL pipeline.
FounderFlow
GitHub- Built a financial analytics backend for tracking startup burn rates, runway forecasts, and asset allocations.
- Engineered role-based access control (Founder, Investor, Admin) and a stage-based investor matchmaking and funding pipeline using REST APIs and PostgreSQL.
Winner · Centific Premier Hackathon 2.0
by @Centific (Hyderabad)- Selected as an individual winner in the AI System Engineering track, building high-throughput AI workflow architectures.
- Read the announcement on X (Twitter) and LinkedIn.
Finalist · Odoo Hackathon 2026
by @Odoo India HQ, Gandhinagar- Advanced through the intensive virtual qualifier to compete as a national finalist in the 24-hour offline hackathon at Odoo India HQ (Gandhinagar), building solutions under live surprise problem statements.
2nd Place · Google Developer Group (GDG) AI Competition
100+ Participants- Secured 2nd rank for rapid system prototyping and applied artificial intelligence architecture.
- Solved 400+ algorithmic problems across LeetCode, GeeksforGeeks, Code360, and CodeChef focusing on core data structures and concurrency.
Technical Writing & Logs
RNNs
I learned about RNNs, And how it works behind the scenes.
Understanding Redis Caching in Modern Backend Systems
Learn how Redis helps backend applications become insanely fast using in-memory caching, session storage, and real-time data handling.
Quick Notes & Learning Logs (TIL)
Implemented CI and CD: wrote tests, ran into build and type issues, and resolved each on the fly. Key learnings in pipeline stability.
Explored database table partitioning strategies for high-volume relational schemas and query performance.
Worked with AWS EC2 instance provisioning, compute management, and security group routing.
Studied the core pillars of System Design: horizontal scaling, load balancing, caching tiers, and CAP theorem trade-offs.
