I’m an Applied ML / AI Engineer and Data Scientist with 6+ years of practical experience building production-ready AI systems across Computer Vision, NLP, RAG, AI agents, time-series modelling, and MLOps-style deployment. I specialize in object detection, image classification, segmentation, OCR, face recognition, tracking, defect inspection, real-time video analytics, semantic search, chatbots, and AI-agent workflows. I have built YOLO/OpenCV-based vision systems, PaddleOCR/ANPR pipelines, RAG applications with pgvector/Postgres, LangGraph/LangChain agents, ASR/voice-search services, and production APIs using FastAPI/Flask, Docker, and cloud infrastructure. My focus is not just model training, but complete deployable solutions: data pipelines, model tuning, inference APIs, dashboards, logging, documentation, and client-ready handoff.
The system works end-to-end as expected and it provides a solid foundation for what I need

Devansh delivered excellent work on this project. He approached a difficult technical problem methodically and thoughtfully, built substantial exploratory tooling, ran structured experiments, and helped turn vague hypotheses into concrete, testable models. He communicated clearly, summarised results well, and explained each experiment and its implications effectively. His work showed persistence, strong technical fluency, and professionalism. I would highly recommend him.
