Raj Kumbhaj - Software Developer

Overview

An entry-level backend developer (intern-level) focused on building small full-stack prototypes and REST endpoints. No original, developer-owned code artifacts are evidenced for a concrete proven backend skill in the analyzed files. Public material does not demonstrate independent design work, transaction/concurrency decisions, production-grade resilience, or a migration history.

Projects

Water Quality Prediction

Developed a water quality prediction workflow with emphasis on data preprocessing and reliability. Improved model readiness using data cleaning and visualization with Pandas, NumPy, and Matplotlib. Focused on making the dataset and features more consistent prior to training and evaluation.

DineFlow

Engineered a full-stack reservation system with a Spring Boot backend, React UI, JWT-based auth, and a MySQL data layer. Added double-booking prevention using a conflict-detection algorithm and implemented an order workflow with price snapshotting and strict state transitions. Built admin reporting using query-based views and scheduled automation to expire no-show reservations.

Agentic RAG Assistant

Built a full-stack agentic RAG assistant that routes user questions across PDFs, SQL data, and web search using an LLM planner. Implemented anonymous multi-tenant isolation with per-browser identifiers and automated TTL cleanup across documents, database records, and vector embeddings. Designed a provider-agnostic LLM integration layer supporting multiple model providers and deployed the React/FastAPI application to cloud hosting.

Recommendations

Work on end-to-end small backend features that you own from design to tests, such as a REST endpoint with input validation, DB migration, and unit/integration tests.
Build experience with schema evolution by creating and documenting a migration chain (create, evolve, roll back) and include tests for data integrity.
Develop resilience patterns on a single service: add timeouts, retries with exponential backoff and jitter, graceful shutdown handling, and automated tests for failure modes.
