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.

Need a developer who can build the whole thing and ship it? I do full-stack apps, data pipelines, and automation end to end. Next.js and React on the front, Python and Node on the back, Postgres underneath, APIs wired clean. I've shipped real products, not demos. A vacation-rental booking platform with Stripe, calendar sync and a multi-property admin dashboard. A real-estate course platform with Stripe checkout, auth, and a student portal. Both live and used daily. On the data and automation side, I build Python and PostgreSQL pipelines that ingest messy sources, parse and normalize them, dedupe, and load clean data you can trust, with idempotent reruns so nothing double-loads. I wire n8n and API integrations between tools, webhooks, bidirectional sync, and the loop-prevention and rate-limiting that keeps a sync stable. I also build scrapers that get past Cloudflare and Akamai without getting blocked. When AI actually fits, I build it in: enrichment and scoring pipelines, document processing, and agents that automate real work. Stack: TypeScript, Python, Go, Next.js, React, Node, FastAPI, PostgreSQL, MongoDB, Supabase, Stripe, n8n, OpenAI, Docker, plus most major REST APIs. I'm Top Rated with a 100% job success score. I hit deadlines, I explain things in plain English, and I build things that keep running after I hand them over instead of breaking the next week. If you've got something to build or two systems to connect, send me the details and I'll tell you straight how I'd do it and where the risks are.
