⚡ I build production-ready, AI-powered web applications — from model training to fully deployed web products.
With 7+ years of hands-on experience across full-stack development and AI/ML engineering, I specialize in one thing most developers can't offer: the full picture. I don't just integrate an API and call it "AI" — I architect robust, scalable systems where the AI layer genuinely solves your business problem.
If you need a freelancer who can handle the entire stack — AI/ML backend, REST APIs, and polished frontend — you've found your person.
What I build for clients:
✅ ML model development, fine-tuning & deployment (PyTorch, TensorFlow and more)
✅ LLM API Integration. GPT, Claude, Gemini integration into existing SaaS, CRMs, ERP & Web apps
✅ RAG systems — "chat with your documents" (PDFs, databases, wikis)
✅ AI agents & autonomous workflow automation (LangChain, CrewAI, LangGraph
✅ Custom AI chatbots & LLM-powered apps (GPT, Claude, Gemini, Llama)
✅ Full stack web applications (React/Next.js + Python/FastAPI/Django)
✅ Data pipelines, annotation systems & MLOps infrastructure
✅ Cloud deployment AWS, Google Cloud, Azure, Digital and many more
⚙️ Tech Stack at a glance:
→ AI/ML: Python · PyTorch · TensorFlow · Scikit-learn · HuggingFace · OpenAI API · Anthropic API
→ LLM Frameworks: LangChain · LlamaIndex · LangGraph · CrewAI
→ Vector DBs: Pinecone · Weaviate · ChromaDB · FAISS
→ Backend: FastAPI · Django · Node.js · PostgreSQL · MongoDB
→ Frontend: React · Next.js · TypeScript · Tailwind CSS
→ Cloud/MLOps: AWS · GCP · Docker · GitHub Actions · SageMaker
💡 Why Clients Choose Me:
Most ML engineers can't build a polished, deployable product.
Most full-stack developers don't truly understand AI systems.
I bridge both worlds — and I've done it for 7+ years.
You get a developer who:
→ Understands your business problem first, code second
→ Delivers working systems, not just demos or prototypes
→ Communicates clearly throughout — no technical black boxes
→ Has seen enough projects to know what breaks in production
I work with startups, SMBs, and enterprise teams across the US, UK, EU, and Middle East. Whether it's a greenfield AI product or adding intelligence to your existing platform, I bring the same rigorous engineering approach.
I focus on outcomes that matter: systems that save you time, reduce costs, or generate revenue.
