About Siddharth Jindal

I am a Software Engineer specializing in Generative AI, Retrieval-Augmented Generation (RAG), and Full Stack Development, with a strong foundation in C++ and competitive programming. I enjoy building intelligent, scalable systems that combine deep technical understanding with real-world problem solving.My experience spans developing AI-powered applications using LLMs, LangChain, vector databases, and NLP pipelines, as well as building full-stack solutions using React, Node.js, Express, and MongoDB. I have worked on end-to-end projects—from backend logic and APIs to frontend interfaces and AI integration—ensuring performance, reliability, and user-centric design.Alongside development, I actively practice C++ and algorithms as a competitive programmer (CodeChef, Codeforces), which strengthens my problem-solving, data structures knowledge, and time-efficient coding abilities.Core StrengthsGenerative AI & RAG: LLM integration, vector search, LangChain workflows, NLPFull Stack Development: React, Node.js, Express, MongoDBC++ Competitive Programming: DSA, algorithms, optimization, problem-solvingSoftware Engineering: Clean code, scalability, API design, system thinkingI’m passionate about building meaningful, technically strong projects and continuously sharpening my skills through both engineering work and competitive programming.
