Hartej Singh — Software Engineer
I’m a passionate Python developer and AI enthusiast with over 3.5 years of hands-on experience building scalable backend systems and intelligent GenAI solutions. My journey began with a deep love for problem-solving and has evolved into architecting full-stack AI systems that deliver real-world impact. My current focus lies in developing production-grade Generative AI applications—integrating large language models (LLMs), designing Retrieval-Augmented Generation (RAG) pipelines, and building agent-based workflows to automate and enhance decision-making. I’ve worked extensively with models like OpenAI, Claude, and Vertex AI (Gemini), applying them across use cases including function calling, multi-agent orchestration, and real-time query handling. On the backend, I specialize in Python (Flask, FastAPI, Pydantic), microservice design, and serverless/cloud-native deployments using GCP (Kubernetes, Cloud Run, Workbench VMs). I’ve also engineered advanced RAG systems using pgvector, Pinecone, BigQuery, and MongoDB—optimizing semantic search and retrieval with HNSW and ScaNN techniques. Formerly a Product Owner on a GenAI search project, I’ve led teams, improved latency and accuracy by over 25%, and helped clients reduce time-to-information by 50% through intelligent automation. Core Skills Python • Flask/FastAPI • GenAI • LLMs (OpenAI, Claude, Gemini) • Prompt Engineering • RAG • NLP • Vector DBs (pgvector, Pinecone) • GCP • Kubernetes • CI/CD • GraphQL • WebSockets • MongoDB • AlloyDB • BigQuery Outside of code, I’m a big motor-head and staying immersed in tech innovations. I’m always eager to connect with like-minded individuals passionate about AI, backend engineering, or building the future with GenAI.
