I define the data, the model approach and the evaluation metric before writing training code, so "done" is measurable rather than argued about. Milestones with written acceptance criteria, or hourly with daily updates. Your choice. You own the code, the model weights and the infrastructure. NDA and IP assignment on request. Send me your dataset, your accuracy target, or the pipeline you have now, and I will come back with an approach, the risks, and an estimate.

I build AI agents, RAG systems, voice AI, and workflow automations that help businesses reduce manual work, connect their tools, and operate more efficiently. If your team is spending too much time on repetitive tasks, scattered data, lead follow-ups, customer support, document processing, reporting, or moving information between different platforms, I can design and build an AI-powered system around your actual workflow. My focus is not just creating AI demos or prototypes. I build practical, production-ready solutions that integrate with your existing tools, APIs, databases, CRMs, and business processes. ✔ 𝗪𝗵𝗮𝘁 𝗜 𝗖𝗮𝗻 𝗕𝘂𝗶𝗹𝗱 ➡ AI Agents & Multi-Agent Systems ➡ AI Voice Agents & AI Receptionists ➡ RAG Chatbots & Knowledge Assistants ➡ Custom LLM Applications ➡ n8n Workflow Automation ➡ CRM & Lead Follow-Up Automation ➡ Email & Customer Support Automation ➡ Document Intelligence Systems ➡ Internal Company Knowledge Bases ➡ AI-Powered Reporting & Data Workflows ➡ API & Webhook Integrations ➡ FastAPI AI Backends ➡ ETL & Data Pipelines ➡ Custom Machine Learning & NLP Solutions ✔ 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀 & 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 I can build intelligent workflows that connect AI with the tools your business already uses.

I help businesses implement practical AI-powered solutions that automate processes, reduce costs, improve team efficiency, and turn business data into intelligent systems. With 7+ years in the Microsoft ecosystem, Power Platform and AI space (Power Apps Code Apps, Power Automate, Copilot, AI Foundry, and Microsoft Agent Framework), and in business systems architecture, I work as a technology partner to organizations seeking to replace manual processes with intelligent, scalable solutions. I help organizations move beyond AI experiments into production-ready solutions that deliver measurable efficiency gains. Here are some of the automations I have implemented for businesses: Clinical Trial Management System Automated Invoice Management System (AI OCR + approval workflows) Quote Builder & Quote Management Application Project Stage / Milestone Tracking Application Law Firm Case Management System Lead, Project & Staff Allocation System Leave Management System Document Management System (SharePoint + Power Platform) Inventory Management System Employee Assessment & Skill Evaluation Platform Research Project Management System If you’re looking for someone who understands both technology and business processes, I’d be glad to help.

Last project: a multi-agent system that handles end-to-end case evaluation for a legal client, replacing what used to be hours of manual review. That's the kind of problem I like — turning a messy, manual workflow into a reliable automated system. I'm a Senior AI Engineer (5+ years) specializing in RAG pipelines, multi-agent architectures, and production LLM systems — from whiteboard to AWS deployment. Recent work: Built a multi-agent legal AI system — a conversational intake agent that evaluates cases and recommends outcomes in real time Designed a RAG pipeline over a dense regulatory corpus, cutting document retrieval time by 60%+ Built an e-commerce shopping agent (Amazon/eBay) using LLM-based intent classification — replacing hardcoded category logic with a dynamic query mapper Shipped scalable AI APIs handling thousands of daily requests at sub-200ms latency What I bring beyond code: I scope projects like a product engineer first — defining what "done" actually means (POC vs. production-ready) before writing a line of code. That means clearer expectations, fewer pivots, and timelines that hold. Stack: Languages: Python, Node.js LLM frameworks: LangChain, LlamaIndex, OpenAI, Claude, HuggingFace, Ollama Vector DBs: Pinecone, Weaviate, ChromaDB, pgvector Agent frameworks: AutoGen, CrewAI, LangGraph Cloud & MLOps: AWS (SageMaker, Bedrock, Lambda, S3, EC2), Docker, FastAPI Databases: PostgreSQL, MongoDB, Redis Search: Elasticsearch, FAISS Bonus: I also work fluently across English, French, and Arabic — useful if your project involves multilingual content, MENA markets, or non-English document corpora. I work autonomously and communicate proactively — you'll know exactly where a project stands at every stage, with no surprises near a deadline. If you need an AI engineer who can own both technical architecture and product judgment — let's talk.
