Work Experience
Backend Engineering Intern · Exanor
April 2026 — July 2026Hybrid, Internship
- 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.
Featured Projects
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.
