I’m an AI & Python Engineer focused on building full-stack backend systems, scalable APIs, and production-ready AI applications. I specialize in turning complex ideas into real systems—whether that’s backend architecture, cloud services, or AI-powered applications using LLMs and agent-based workflows. I’ve built and shipped systems ranging from high-scale backend platforms processing tens of millions of events, to multi-agent AI research tools and RAG-based knowledge systems. I like clean architecture, predictable systems, and code that doesn’t fight you at 2 AM. Core focus areas: • AI systems (LLMs, RAG, multi-agent workflows) • Python backend development (Django, FastAPI) • API design & system architecture • Scalable cloud systems (AWS, Docker, Kubernetes) • Databases & performance optimization (PostgreSQL, Redis, MongoDB) • Full-stack application development If you need something simple, I can build it fast. If you need something complex, I can make it understandable, scalable, and maintainable.

Your data pipeline runs. Until it doesn't !! and then someone on your team spends the rest of the day manually patching it back together while the actual work piles up. I'm a Senior AI Automation and Data Engineer with five years of production experience, three of them inside a UK fintech building systems that process over ten million records a day and cannot afford to fail. The result I'm most proud of: I took a 4–5TB fintech migration that was eating three full days of engineering time and rebuilt it as a fully automated validation and migration tool. It now runs in fifteen minutes, unattended, every time. What I actually build: end-to-end Python ETL pipelines, AI agents using OpenAI and Claude APIs, complex n8n and Make com workflow systems, and RAG architectures on top of PostgreSQL and SQL Server. I work at the architecture level, not the template level — which means what I build does not break when your data volume doubles or your upstream schema changes. Working with me looks like this: I join a short call to understand the business problem first, then I come back with a specific architecture proposal before I write a single line of code. You get documentation, you get a system you can hand to your next engineer, and you stop hearing about the process breaking. If you have a workflow that still needs a human in the middle of it, send me a message describing it. I'll tell you exactly how I'd remove that dependency.

I build production-ready AI systems RAG pipelines, AI agents, and LLM-powered apps , that turn messy data and manual processes into reliable, automated workflows. 21 projects delivered on Upwork with a 100% Job Success score. Most AI projects look great in a demo and break in production. I focus on the opposite: systems that stay accurate, fast, and affordable once real users and real data hit them. Here's what I help clients build: • RAG systems : chatbots and Q&A tools that answer from your own documents, knowledge bases, and data, with proper retrieval and minimal hallucination • AI agents & automation : multi-step agents that research, summarize, and take actions using LangChain and LangGraph • LLM integration : connecting OpenAI, Anthropic Claude, and open-source models (Llama, Mistral) into your product or internal tools • Optimization : fine-tuning, prompt engineering, and caching to push accuracy up and API costs down My typical stack : Python, LangChain, LangGraph, LlamaIndex, FastAPI, vector databases (Pinecone, Chroma, FAISS), Hugging Face, Docker, and AWS/GCP/Azure. I communicate clearly, scope honestly, and tell you when an AI solution is overkill versus when it's the right call. That's a big part of why my clients keep coming back. A few recent results: • Built a RAG chatbot over 500+ documents that cut support response time more than half. • Reduced LLM API costs by 40% through prompt optimisation and caching. • Shipped an AI agent that automated 10 tasks, saving the team 20 hours per week. If you have an AI idea anything from a quick prototype to a full production system send me a message describing what you're trying to build. I'll reply with an honest take on how I'd approach it, what it would realistically take, and whether it's worth doing.

If your Power BI reports are broken, your data isn’t trustworthy, or you need a BI system built properly from scratch, you've come to the right place. Most Power BI freelancers stop at pretty visuals. I fix what’s broken underneath. 🔧 I’m Muhammad Amir Khan, a Data & BI Team Lead and Senior Business Intelligence Engineer with 7 years of experience building Power BI solutions that executives actually trust and use. While most developers focus only on dashboards, I work from the data layer upward: source-level cleanup, Power Query transformations, semantic modeling, advanced DAX, Row Level Security, refresh, deployment, governance, and performance optimization. Currently, I lead the Data & BI function for a $20M ARR aviation company in the Middle East, where I’ve built 15+ production Power BI dashboards that eliminated 90%+ of spreadsheet-based reporting for executive leadership. 💡 What I Do Best Power BI Rescue & Optimization If your report has incorrect totals, duplicate rows, slow refreshes, broken DAX, RLS issues, or numbers that don’t match the source data, I diagnose and fix it. Common issues I solve: • Duplicate rows and grain mismatches • Broken DAX and incorrect aggregations • Refresh failures and performance bottlenecks • RLS not filtering correctly • Timezone and date logic inconsistencies • Dashboard data not matching source data These are the problems most freelancers struggle to isolate. End-to-End BI Solutions I build complete BI systems, not just reports. From business requirements through data modeling to executive dashboards, I create scalable single sources of truth. Recent example: built QualDerm Partners’ Triage & Referral Dashboards with 30+ DAX measures on Snowflake, including full semantic model documentation. Advanced DAX & Data Modeling • Context transition, time intelligence, and debugging • Field Parameters and dynamic reporting • Row Level Security across multi-entity structures • Star schema design from messy operational data • Performance optimization for large models Multi-Source Data Consolidation I unify data from: • Excel files, SharePoint lists, and document libraries • Azure SQL, SQL Server, and on-prem databases • REST APIs and SaaS connectors • BigQuery, Snowflake, and Fabric • Power Query ingestion with proper refresh and error handling 🛠️ Technical Stack • Power BI: DAX, Power Query, RLS, Field Parameters, DirectQuery, Deployment Pipelines, Power BI Service, Governance, Security • Data: SQL, BigQuery, Snowflake, PostgreSQL, MySQL • Engineering: Python, Pandas, NumPy, ETL/ELT, Airbyte, Git, REST APIs, AWS, GCP • Visualization: Power BI, Looker Studio • Modeling: Star Schema, Semantic Modeling, Data Warehouse Design, Dimensional Modeling • Certifications: PL-300 | DP-600 in progress 📊 Real Client Outcomes The Helicopter Company Built 15+ Power BI dashboards with RLS and DirectQuery, replacing 90%+ of spreadsheet reporting and giving leadership real-time visibility into mission-critical KPIs. QualDerm Partners Built Triage, Call Center, and Referral dashboards with 30+ advanced DAX measures, full semantic documentation, and ongoing refresh in Power BI Service. Raus Diagnosed a 25% KPI variance caused by API changes, rebuilt Power Query pipelines, and reconciled numbers back to source with a documented validation pack. Munchies Optimized dispatch analytics, reducing delivery time by 15%. GoMotive Built telemetry and reliability dashboards that helped engineering teams drive a 25% reduction in product error rates. 🎯 Who I Work Best With You’re a strong fit if you: • Have a Power BI report with wrong numbers or broken logic • Need a complete BI solution from data to dashboard • Are migrating from Excel, Tableau, Looker, or other tools to Power BI • Need advanced DAX, RLS, performance optimization, or governance • Want a fractional BI lead for 10–20 hours per week I work primarily with mid-market companies across the US, UK, Australia, and Europe. 🤝 How I Work I diagnose problems live on discovery calls instead of relying on long questionnaires. I communicate in plain English unless you want technical depth, and I focus on building systems that are accurate, scalable, and actually used. 🚀 If your Power BI reports are broken, your data isn’t trustworthy, or you need a BI system built properly from scratch, reach out and let’s discuss your project.
