Jayesh Kumar Singh — Full Stack Developer

— Who I Am —

About Me

Full Stack Dev

I'm Jayesh Kumar Singh, a dedicated Full Stack Developer currently pursuing a Bachelor of Technology in Computer Engineering at ABES Engineering College, Ghaziabad (CGPA: 7.38). I specialize in building production-grade applications across the entire stack — from React frontends to Spring Boot microservices.

My expertise spans Java, JavaScript, TypeScript, and Python, with deep proficiency in frameworks like Spring Boot, React, Node.js, and Next.js. I architect systems that are scalable, secure, and performance-optimized — from containerized microservices with Docker to AI-powered RAG pipelines using ChromaDB.

What sets me apart is my dual strength in backend engineering and problem-solving — I've solved 650+ DSA problems on LeetCode with a top 9% global ranking and a contest rating of 1772. I maintain 20+ active GitHub repositories spanning full-stack, backend, and AI projects.

Mission

Featured Projects

Threadly — Microservices E-Commerce

Backend · Distributed Systems

GitHub

A fully distributed microservices e-commerce backend built with Java Spring Boot. Each service (auth, products, orders, cart) is independently deployable with Spring Cloud Eureka service discovery and an API Gateway handling all routing. The system is containerized with Docker for production-ready deployments and secured with JWT + Spring Security role-based authorization.

Architected 4 independent microservices — auth, products, orders, and cart — with dedicated databases per service.

Implemented Eureka service registry and API Gateway for scalable, fault-tolerant inter-service communication.

Secured entire API surface with JWT authentication, Spring Security, and role-based authorization filters.

Containerized all services using Docker and docker-compose — enabling one-command full-stack deployment.

AI Video Analytics Platform (RAG)

AI / ML · Full Stack

GitHub

An advanced Retrieval-Augmented Generation (RAG) platform for analyzing YouTube and Instagram video content. The system ingests video transcripts, chunks them into semantic units, generates vector embeddings, and stores them in ChromaDB for similarity search. A Next.js dashboard delivers streaming AI chat with conversational memory and analytics panels.

Built end-to-end RAG pipeline — transcript extraction → chunking → embedding generation → ChromaDB vector storage.

Implemented semantic similarity search with citation tracking for context-aware, source-grounded AI responses.
