I am a Python-based AI and LLM Integration Developer specializing in building intelligent, production-ready applications using OpenAI, LangChain, and FastAPI. My focus is on turning large language models into real, working product features including chatbots, AI assistants, document intelligence tools, and automated workflows that solve actual business problems rather than just demos. On the AI and LLM side I work with OpenAI API, LangChain, RAG pipelines, prompt engineering, vector databases, and embedding-based search to build systems that retrieve and respond with accuracy. Whether you need a customer support chatbot trained on your own data, an AI assistant embedded inside your web app, or an LLM-powered workflow that automates repetitive tasks, I can scope, build, and deliver it cleanly. On the backend I use FastAPI and Django to build the APIs and infrastructure that power these AI features including authentication, database design, third-party integrations, background processing, and deployment. This means I can take a project from zero to a fully working hosted product without needing a separate backend developer. For frontend and mobile I work with Next.js for web and Flutter or React Native for iOS and Android, so if your AI-powered product needs a complete interface I can handle that as well. I have delivered full stack web platforms, SaaS dashboards, LMS systems, and mobile apps across fintech, edtech, healthcare, and logistics verticals. If you are building something that needs AI at its core such as a chatbot, an intelligent search tool, a document assistant, or an LLM-powered SaaS feature, send me a message and I will respond with a clear plan for how we can build it.

I build backend services and AI-powered systems ready for real-world use. With 2+ years of experience, I deliver production-ready services, AI cloud integrations, and take full technical ownership - managing delivery, solving challenges, and collaborating directly with CTOs. Skills: 🚀 AI Integration: AI agents (Voice agents , chat bots, data processing), Text-to-Speech, Speech-to-Text, Computer Vision 🧠 RAG Systems (AI Search): LangChain, vector databases, embeddings, prompt engineering ☁️ Cloud Integration: API-based model deployment, service orchestration 🛠️ Backend Development: FastAPI, SQL, Docker, Git, CI/CD Scalable, maintainable, resilient solutions - with a strong focus on real-world robustness, API design, error handling, and production-readiness. If you need someone technical, fast, and thinking like a product owner - let's work together!
