⚡ 1M+ rows processed daily. 30K pages/day scraped at 99.95% uptime. Report generation cut from 3 hours to 2 minutes. As a Senior Python Data Engineer and Big Data specialist with 10+ years of experience, I build Python Web Scraping and Data Extraction systems, ETL/ELT pipelines, and GCP BigQuery infrastructure for businesses that need their data to work — automatically, reliably, and at scale. Every project I take on is approached with the precision and depth that only a seasoned Python Data Engineer can bring. If your team is still collecting data manually, waiting hours for reports, or getting blocked by anti-bot systems - I'm the Python Data Engineer who builds the Big Data pipelines and Web Scraping systems that eliminate that entirely. 💡 Core Specializations: ⚙️ Big Data Engineering & ETL/ELT Pipelines End-to-end Python Data Engineer pipeline design and implementation: extraction, transformation, loading, orchestration, and monitoring. As a dedicated Python Data Engineer, I work with Airflow, dbt, and Dagster for workflow management, BigQuery and PostgreSQL as primary data stores, and GCP and Azure as cloud infrastructure. Full logging, alerting (Slack, Telegram, email), and failure recovery are included as standard in every Python Data Engineer engagement. Teams save 30–80+ hours per month through ETL pipeline automation delivered by an experienced Python Data Engineer. 🕸 Python Web Scraping & Data Extraction Large-scale Web Scraping development using Scrapy, Selenium, Playwright, and BeautifulSoup - built and maintained by a dedicated Python Data Engineer.

Power BI developer + Data Engineering — I build the automated pipelines (Databricks, ADF, SQL, Fivetran) and the dashboards leadership trusts, end to end. If your team is still pulling numbers by hand, stitching exports together, and quietly not trusting what's in the report — your data isn't slow, it's unbuilt. And every decision made on top of it is shakier than it should be. I'm a data engineer and BI specialist with 13+ years building the full path from raw, messy source data to the dashboards leadership actually trusts. Co-founder of GrowthBI, an analytics consultancy serving scaling companies across Australia, Europe, and the US. Here's what makes me different: most freelancers do one half. Pure data engineers hand you clean tables and no story. Pure dashboard builders make polished reports on top of data that breaks every week. I build both halves — the pipeline and the reporting — so you hire one person instead of managing two. 80%+ of my clients come back for follow-on work. Where I deliver the most impact: → Data pipelines & automation — Fivetran, DBT, SQL pipelines that ingest from SAP, CRMs, ad platforms, and spreadsheets, model the data in Databricks/BigQuery, and refresh on a schedule so reports build themselves → Data modelling & warehousing — clean, documented, single-source-of-truth tables your whole team can rely on → Power BI & Looker Studio dashboards for marketing, product, sales, and finance leadership → Executive reporting — YTD, MTD, YOY, and scenario comparisons leadership can act on → Customer & growth analytics — RFM modelling, cohort analysis, churn prediction, CAC vs. LTV, channel attribution → Row-level security (RLS) & governance for multi-team and multi-entity reporting Results I've delivered: → Consolidated [X] disconnected sources into one automated pipeline — eliminated ~[X] hrs/week of manual reporting and gave leadership numbers they could finally trust → 10x growth in customer acquisition — surfaced channel-mix insights that reshaped how a leadership team allocated marketing spend → 10% churn reduction — identified the highest-risk customer cohort with RFM segmentation and built a live re-activation tracker for the sales team → Prevented significant revenue loss — caught a payment failure from a default product setting before it compounded, with a live monitoring dashboard run until the fix shipped My core stack: SQL · DBT · Fivetran · Databricks · BigQuery · Power BI · DAX · Power Query · Alteryx · SSIS · Excel Industries: E-commerce · SaaS · Real Estate · Financial Services · Insurance · Consumer Goods Clients I've worked with: Rate My Agent · Keep It Cleaner · Montgomery Homes · Peeplcoach · Paylater · Joolca I work directly with C-suite leaders, senior leadership teams, and cross-functional analysts. I understand what each team needs to answer — and I build the data layer and the dashboards that answer it, without a manual every time.

The job was delivered ahead of schedule. He was enthusiastic and professional and went the extra mile to make sure the job was completed to our liking with the tech that we were already using. I enjoyed working with him and will be reaching out for any additional help in the future. I would definitely recommend Anas as an expert resource. ❞ ⭐️⭐️⭐️⭐️⭐️ 🗣❝ Muhammad was a great resource and did more than expected! I loved his communication skills and always kept me up to date. I would definitely rehire again. ❞ ⭐️⭐️⭐️⭐️⭐️ 🗣❝ Anas is simply the best person I have ever come across. Apart from being an exceptional tech genius, he is a man of utmost stature. We blasted off with our startup, high on dreams and code. We were mere steps from the MVP. Then, pandemic crash. Team bailed, funding dried up. Me and my partner were stranded and dread gnawed at us. A hefty chunk of cash, Anas and his team's livelihood, hung in the balance, It felt like a betrayal. We scheduled a meeting with Anas to let him know we were quitting and request to repay him gradually over a year, he heard us out. Then, something magical happened. A smile. "Forget it," he said, not a flicker of doubt in his voice. "The project matters. Let's make it happen!" We were floored. This guy, owed a small fortune, just waved it away? Not only that, he offered to keep building, even pulled his team in to replace our vanished crew. As he spoke, his passion was a spark that reignited us. He believed. In us. In our dream. In what he had developed so far. That's the day Anas became our partner. Not just a contractor, but a brother in arms. Our success story owes its spark not to our own leap of faith, but from the guy who had every reason to walk away. Thanks, Anas, for believing when we couldn't.❞

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.

I build BigQuery warehouses, dashboards, and increasingly the AI and LLM layer that goes on top of them. For the last six years I've consulted for companies ranging from big-box retailers to Y-Combinator tech startups to help them get out from under manual reporting and scattered data. Most recently I've been building RAG systems and LLM observability for industrial SaaS applications, alongside the BigQuery, executive dashboards, and data engineering work (ETL) that has been my main lane for years. What I help clients build: • RAG and LLM systems. Production RAG over your business data (Claude, Gemini, GPT, vector stores), prompt and retrieval evaluation, dashboards for LLM cost, latency, and accuracy, and agentic workflows that connect tools to action. • BigQuery warehouses and ETL. Schema design, partitioning, cost cleanup, plus Python pipelines that ingest from Quickbooks, Stripe, GHL, HubSpot, GA4, Shopify, Filevine, and a long list of custom APIs. HIPAA-compliant when it needs to be. • Dashboards that actually get used. Looker Studio, Metabase, and ThoughtSpot (avoid PowerBI and Tableau like the plague). I always prototype the dashboard, so you see the end result first, we don't build pipelines you don't need, and I can give you a fixed-price quote (most freelancers will never give fixed-price quotes). • Internal tools and automations. Cloud Functions, Cloud Run, Slack and email integrations, Stripe billing, scheduled syncs. Things that should just run quietly in the background and stop being someone's manual job. A few things to know about working with me: I've hired freelancers on Upwork myself, so I know the difference between someone who hides behind their service and someone who moves the business forward. I write SQL and Python the next engineer can read without a guide. I'll tell you when the fancy version of a thing isn't worth building. I prefer working off real data and screenshots over abstract requirements docs. I have adopted AI tools that help me to complete data projects in 7 days by myself that used to take me 12 weeks with a small team.
