If your data pipelines are slow, breaking, or producing dashboards your team doesn’t trust — I fix that. Most data engineers can build a pipeline. Fewer make sure it is fast, reliable, well-modeled, and feeding dashboards your business can actually use for decisions. I’m a Microsoft Certified Fabric Data Engineer specializing in Microsoft Fabric, Azure data pipelines, Lakehouse/Warehouse architecture, Databricks, Snowflake, and Power BI semantic models. I help teams build the full data layer: from raw source systems and APIs, to clean Bronze/Silver/Gold pipelines, to properly modeled warehouses, to Power BI dashboards that perform at scale. Recent results: * Reduced a daily pipeline runtime from 8 hours to 30 minutes * Eliminated around 95% of manual data errors by automating third-party API integrations * Saved a data team 20+ hours per week through automated monitoring and reporting * Reduced manual data preparation time by 60% with end-to-end Azure pipelines * Built Power BI dashboards for retail, sales, and supply chain clients, with 5-star client feedback What I can help with: * Microsoft Fabric pipelines, Lakehouse, Warehouse, and medallion architecture * Azure Data Factory, Databricks, Azure SQL, and Data Lake pipelines * PySpark and Spark SQL for large-scale data processing * Power BI semantic models, DAX optimization, and executive dashboards * Data modeling, star schemas, fact/dimension design, and ERDs * SQL optimization, data quality checks, and pipeline monitoring * Snowflake and dbt for modern cloud warehouse solutions How I work: * Clear communication and regular project updates * Loom walkthroughs for architecture, logic, and deliverables * Clean, documented, production-ready code your team can maintain * Strong focus on reliability, data quality, and long-term maintainability * Available for async collaboration across US, UK, and EU time zones If you need reliable pipelines, clean data models, and dashboards your team can trust, send me a message.

If your data is stuck in the wrong system, in messy files, or behind an awkward API, I can help. I turn complex data problems into working systems and usable deliverables. I help clients move data between platforms, automate manual work, clean up unreliable exports, and build workflows that save time and reduce errors. Whether the deliverable is a program they can keep using, or a clean CSV, Excel file, report, or database, I can make it happen. Most of my work is API integrations, ETL pipelines, backend automation, data processing, and data migrations. I'm at my best when the problem is not clean or perfectly defined. I'll solve that problem first. I build data workflows that are meant to hold up in real use. I work with complex APIs, big JSON or XML data files, elaborate schema, folders full of CSV and Excel files, and large datasets where correctness matters. The result is a cleaner dataset, a dependable program, or a responsive and well-designed workflow. If you need a dependable program, a solid new system, or a clean final dataset, I can help.

Most software projects don’t fail because of the code. They fail because of a disconnect between the business vision and technical reality. 👋 My name is Ronan Murphy. For over 8 years, I have acted as a hands-on technical operator and strategic partner for startups, solo entrepreneurs, and global enterprises alike. Based out of Dubai, I bridge the gap between high-level operational goals and rugged, scalable software infrastructure across Finance, HVAC/IoT, and Oil & Gas. My clients don’t leave me because I build with a Zero-Tolerance framework for data drift, system lag, and budget runaway. I do not bypass potential structural holes or ignore underlying failure roots just to ship a feature faster. I speak up early, challenge ambiguous metrics, and expose hidden technical friction before it costs you capital. My goal is simple: maximize your operational profit while protecting your bottom line. 🏆 Why Most Freelancers Fail Your Project (And Why I Don’t) If you have hired contractors before, you’ve likely experienced the standard pitfalls: developers ghosting when a feature gets difficult, missing deadlines due to a day job, or building exactly what you asked for even when they knew it would break your budget. I run my practice on an entirely different set of operational ethics. The absolute success of your product and the protection of your business capital are the entire reasons my consulting practice exists. Here is exactly how I distinguish my services from the rest of the market: ✅ Proven Adaptability Across the Business Lifecycle: I have engineered systems across the entire corporate spectrum, adapting seamlessly to the unique friction points of each tier: - Solo Entrepreneurs: I act as a technical co-pilot, turning raw ideas into highly practical tools that optimize day-to-day operations and maximize solo margins. - High-Growth Startups: I build lean, high-velocity MVPs designed to hit market validation rapidly, preserving your runway while building an architecture robust enough to secure your next funding round. - Global Enterprises: I integrate flawlessly into existing enterprise structures—running on strict compliance, signing NDAs without friction, participating in daily standups, and delivering clean, fully documented code that aligns with internal governance. ✅ This is My Dedicated Corporate Career, Not a Side-Hustle: I am a full-time, professional IT consultant. I do not squeeze your project into my evenings or treat your architecture as a weekend hobby. Because this is my full-time dedication, I have the absolute flexibility to fully overlap with your team’s working hours and timezones. You will never have to chase me down for an update or suffer from radio silence because of a corporate day job. ✅ My Professional Working Ethic: Your Success First, Money Second: I am an ecosystem partner, not a transactional vendor. I measure my value by the longevity of my client relationships, many of which span years. If your business encounters a temporary funding bottleneck or a pre-revenue hurdle, I do not vanish. I have consistently stepped up to provide free technical audits, engineer lightweight Proof of Concepts (POCs), or restructure milestones to keep the momentum alive until you achieve market traction. I do not give up on a client who is fighting for their vision. ✅ I Speak Up Early to Protect Your Capital: I don’t quietly build flawed logic just to bill hours. If an initial requirement contains structural holes, edge-case failures, or hidden technical debt, I will speak up clearly and early. I will challenge unoptimized choices before they hit your bank account, saving you thousands of dollars in wasted development cycles. ✅ Domain Mastery on Day One: You don’t waste billable hours teaching me basic business terms, compliance rules, or industry formulas. Having spent years embedded within Finance, HVAC/IoT, and Oil & Gas, I understand your operational realities natively. Whether it is job-costing logic, asset telemetry streams, or multi-tenant financial isolation, I hit the ground running immediately. 🛠️ Core Toolkit - AI/ML: Jupyter Notebooks, PyTorch, TensorFlow, Scikit-Learn - Data Analysis: Excel, PowerBI, Tableau, Snowflake, ETL, MS Fabric, R, Pandas, NumPy - Web Development: Python/FastAPI/Django, JS/TS/Node.js/NestJS/ExpressJS/Next.js/React.js/Angular/jQuery, C#/ASP.NET, PHP/Laravel/WordPress - Mobile Development: React Native, Flutter, Java/Android, Swift/iOS - Databases: SQL, PostgreSQL, MySQL, SQL Server, MongoDB, Supabase, Redis - Cloud & DevOps: AWS, Azure, Google Cloud, Vercel, Digital Ocean, Netlify, CI/CD, Docker If you are looking for a strategy-only consultant to tell you what is wrong with your business, I am not your guy. If you are looking for a highly responsive technical builder who will understand your vision, protect your capital, and do the heavy lifting required to make it a working operational reality—let’s talk.
