I've spent 25+ years building custom production systems, over $500K worth and more than 20 of those in .NET, and these days I'm focused on AI. I build LLM and RAG pipelines, AI agents, and document-intelligence workflows in Python and .NET, usually for businesses whose operations are too unique for off-the-shelf software to fit. The messy, niche, one-off projects most people won't touch are the ones I enjoy most. I automate the manual work that's eating your time and only bring in AI where it genuinely adds value. Hire me when you need something actually built, not just wired together out of existing tools. When the requirements are one of a kind and the domain is a real tangle, I work out the architecture, learn whatever the problem needs, and ship a production system from scratch. That's a big part of why clients stick with me: one for 13 years, another for 4, and a lot of them started with a single project and just kept coming back. "I have yet to give him a hurdle he can't clear." — Scot Nichols, Automotive Diag (2-year client) WHY BUSINESSES CHOOSE ME I don't just build what's on the ticket. I want the actual problem first. Before I write any code I dig into how your business runs: does AI really help here, or would something simpler be more reliable? How will it scale? What will the ongoing model and compute costs look like? Good software, AI or not, has to fit how your business actually works, not whatever's trendy this quarter. I spot the issues you might not see yet — runaway LLM costs, latency under load, multi-user concurrency, awkward integrations — and head them off before they get expensive. I've also helped clients set subscription pricing and cut cloud bills. And I build to last: Clean Architecture, real test coverage, monitoring, and documentation. WHAT SETS ME APART I work across the whole AI and software stack and more than one ecosystem: • AI & LLM engineering — OpenAI, Azure OpenAI, Anthropic/Claude APIs, RAG pipelines (vector + BM25 hybrid, reranking), pgvector, prompt engineering, model selection and benchmarking • AI agents & automation — Microsoft Foundry (Agent Service, Agent Framework), multi-agent orchestration, custom tools via Azure Functions / OpenAPI / Logic Apps / MCP, knowledge-grounded agents over SharePoint / OneLake / Blob, human-in-the-loop approval gates, A2A federation — published into Microsoft Teams and 365 Copilot • Document intelligence — Azure Document Intelligence (prebuilt + custom neural/template models for invoices, receipts, IDs, contracts), Azure AI Search knowledge mining, confidence-scored extraction with human-review routing, PII detection/redaction • Enterprise .NET — ASP.NET Core, Entity Framework, WPF, Clean Architecture • Python data engineering — FastAPI, pandas, Apache Airflow, async processing • Multi-cloud & real-time — Azure, GCP, AWS with Terraform; file monitoring, API integrations, automated workflows When I do use AI, I back it with real numbers, not guesswork — recall@k, MRR, and LLM-as-judge scoring for faithfulness and relevance. For agents that means real guardrails: per-agent identity and RBAC (Microsoft Entra ID), least-privilege tool access, prompt-injection mitigation, approval gates on anything business-critical, and monitoring of citation rates, retrieval accuracy, and token cost. If a plain, non-AI solution is more reliable or cheaper, I'll tell you up front. PORTFOLIO HIGHLIGHTS RAG Pipeline (Security Compliance) — End-to-end RAG over NIST security publications (SP 800-53 Rev 5 + AI RMF). Hybrid retrieval (vector + BM25) with a cross-encoder reranker, measured on a hand-labeled 95-question eval set: recall@5 0.63 → 0.83, MRR 0.48 → 0.64, holding at 10,000-chunk scale. Inline citations, grounded "I don't know", prompt-injection guardrails. Tech: Python, FastAPI, Azure Container Apps, Azure OpenAI, pgvector, Langfuse, CI/CD Automotive Documentation Platform — Multi-tenant system that automated a fully manual Google Sheets process. Syncs PDFs/images from field devices, organizes jobs, generates branded reports, and reconciles with QuickBooks invoices, eliminating missed billing. Built as a multi-tenant Azure SaaS.

Most SaaS demos start in debt. The prospect booked, but they're still not sure the product is for them. The rep spends the first 20 minutes on context your website should have created. By the time you get to fit, urgency, and close, you've already lost momentum. That's a content problem. And it's the one I fix. I rebuild the explanation layer across your website copy, product messaging, use-case content, and BOFU content, around how your product actually works, so buyers arrive at demos already sold on fit, not still figuring out whether your product is for them. This is not content marketing for the sake of publishing. It's a B2B SaaS messaging and content system built from your best product explanation and deployed across every page a buyer touches before they book. Who this is for Most B2B SaaS companies between $500K and $10M ARR have the same problem, even if they describe it differently. Strong product. Real demand. Qualified pipeline. But demo calls that keep starting with the same basic education that should have happened before anyone booked. Sales reps re-explaining what the product does instead of talking about fit, timeline, and next steps. Conversion rates lower than they should be, not because the product is wrong, but because the message isn't carrying its weight. The version of this that works looks different. Buyers arrive already clear on what the product does, whether it fits their workflow, and why it matters for them. The rep doesn't rebuild context. They don't re-explain the use case. They open on fit, move to implementation, and close. That's not a content upgrade. It's what happens when the explanation layer is rebuilt from scratch.

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.
