About Me
Full-time Freelancer with 7+ years of IT industry and freelance experience specializing in LLM inference, training and application development, AI Agent development using LLMs, API development with Python+Flask/FastAPI and NodeJS+Express, and full-stack applications using NextJs.
As a Team Lead for AI & ML at Let's Enkindle, I led a team of 5 developers in building end-to-end AI/ML/DL products, including LLM-powered Text-to-SQL applications, fine-tuning pipelines for Large Language Models, and image search functionality for enterprise clients. Previously, I served as Lead AI & ML Developer at The Other Fruit/Nes Tech Ltd, where I developed cutting-edge solutions including image similarity search engines, face recognition systems, voice authentication, and toxic comment classifiers.
I have successfully built 100+ Google Dialogflow ES/CX Chatbots for clients worldwide through Fiverr and Upwork, demonstrating expertise in conversational AI and chatbot development. My work spans across AI/ML/DL projects in Image Classification, Object Detection, Natural Language Processing (NLP), and search engine development using Vector Databases.
With a background as an Assistant Professor for 6+ years at Government Engineering College, Modasa, I bring both academic rigor and practical industry experience to every project. I hold a Master of Engineering in Power System (CPI 8.3) and continue to share my knowledge as a part-time YouTuber, creating educational content on Google Dialogflow, Machine Learning, NLP, and Large Language Models.
My expertise includes AI Agent Development using OpenAI Agent SDK and Google ADK, fine-tuning and inference of Large Language Models, and building production-ready AI systems on GCP and AWS. I'm passionate about leveraging cutting-edge AI technologies to solve real-world problems and delivering high-quality, scalable solutions.
