At Fabulous Technology Solutions (Fabtechsol), I built and maintained backend architecture for Staron.ai using FastAPI and Django, including APIs, authentication, database models, and core business logic. I also integrated AI-driven solutions and developed RAG pipelines with LangChain, vector stores, and OpenAI embeddings for document Q&A.
I integrated Stripe payments end-to-end, including SetupIntents, Checkout Sessions, webhooks, wallet management, and featured deal billing. I also built WebSocket-based notifications for booking updates, pool requests, and provider-customer communication.
At Devticks, I built AI-powered applications with LangChain, LangGraph, and RAG pipelines, including chatbot MVPs and knowledge-based assistants. I also developed backend services with Django and Tornado and implemented RESTful APIs for mobile and web frontends.
At Ultimate Outsourcing Ltd, I built a pipeline to extract structured information from CVs using NLP and Hugging Face transformer models, and fine-tuned pre-trained models on labeled CV datasets. My projects also include a Bible study chatbot, a natural-language-to-SQL bot, and an AI-powered Flutter IDE.
