AI Agent and RAG systems that reach production, not just demos. I have built LangGraph pipelines, multi-agent systems, and LLM apps deployed on real infrastructure for clients in insurance, recruitment, SaaS and e.t.c. Response within 2 hours. In 2 years across Readfly and Physar Agency, I have shipped: • A hybrid RAG retrieval system using LangChain and OpenAI embeddings for a job-matching platform, cutting candidate search time by over 60% • Predictive ML models for insurance premium pricing using XGBoost and SHAP for explainability, deployed via FastAPI with full MLflow tracking • End-to-end data pipelines automating ingestion from Gmail and SharePoint into Supabase, used in production daily What I build for you: Agentic AI Systems: Multi-agent workflows built with LangGraph and LangChain, agents that plan, retrieve, decide, and act across your tools and APIs. RAG Pipelines: Production retrieval systems using Pinecone, ChromaDB, and semantic search, so your LLM answers from your data, not hallucinations. LLM Applications: Chat interfaces, document Q&A tools, SaaS AI features, built with FastAPI backends, clean APIs, and deployable from day one. ML and Explainable AI: XGBoost, LightGBM, and SHAP-powered models for pricing, classification, and forecasting, with explainability reports for stakeholders who need to understand the output, not just the score. MLOps and Deployment: MLflow experiment tracking, Docker containerisation, CI/CD pipelines, and A/B testing setup, so your model stays reliable after it ships. What makes me different: Most AI engineers hand over a notebook. I hand over a running system. • I design for production from the first line, scalable architecture, clean APIs, monitored deployments • I include drift detection and evaluation (RAGAS for RAG, A/B testing for models) so you know when your AI degrades • I work with MLflow and CI/CD so updates ship without breaking what works • I communicate in plain English, not model metrics your team cannot act on Tech stack: Agentic AI: LangGraph, LangChain, Multi-Agent Systems, Prompt Engineering Vector and Retrieval: Pinecone, ChromaDB, Semantic Search, RAGAS Evaluation ML and Explainability: XGBoost, LightGBM, SHAP, NLP Deployment and MLOps: FastAPI, Docker, MLflow, CI/CD, Drift Detection, A/B Testing Cloud and Data: Azure, MongoDB, PostgreSQL, SQL, Python If you are building an AI product, adding intelligence to an existing platform, or need a system that actually ships, send me a message. I will respond within 2 hours and tell you exactly how I would approach your project.

⚡ 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. 📩 Message me with your project details — let's build something great together. #FullStackDeveloper #MERNStack #AIDevelopment #OpenAI #AIChatbot #Automation #Microservices #AWS #ML Engineer

As a Fractional CTO, I partner with founders and executive teams to bridge the gap between commercial vision and technical execution. Software and platforms I have architected are currently utilised by organisations including the NHS, Aston Martin, Vodafone, GSK, Experian, National Grid and more. My approach is rooted in firsthand experience across the entire product lifecycle. Before building and scaling my own B2B and B2C SaaS companies as a founder, my background spanned senior development, solution architecture, and UI/UX design. Because I have operated at every level of a tech company, I know what excellent execution looks like, how long it should take, and how to align it directly with your business goals. Today, my focus is entirely on technical leadership and strategy. My engagements typically begin with a deep dive into your business: assessing requirements, analysing data, and defining a clear, actionable roadmap. Once the strategy is signed off, I organise the necessary resources and lead the project through to successful deployment. I am completely flexible in how we execute. I can step in to provide structure and leadership to your existing development team, or I can bring in my own, proven, world class, end-to-end product team. This includes senior developers (ex-Google), cloud infrastructure engineers (ex-Serverpod), Senior UI/UX designers (ex-Dept) who have collectively worked on some of the largest products on the planet (Spotify, Google Firebase, The Claridge's Website). If you are looking for an experienced technical partner with an eye for detail to assess your needs, define the plan, and lead the execution from the front, let’s connect.
