She already writes basic Python and SQL, but everything else—cloud services, robust pipelines, modelling, and modern storage patterns—remains a mystery to her. I want a personalised training programme that: • Builds solid foundations in data pipelines, cloud infrastructure, data modelling, and database & storage concepts. • Uses both Microsoft Azure and AWS so she can compare services and deploy end-to-end solutions on each. The format, pace, and depth are open to your professional guidance; however, by the end of the engagement she should be comfortable designing, building, and operating production-ready workflows on either platform.

    I need to streamline the operational datasets that feed our current Power BI reports. The main objective is to redesign and optimise the existing data models so refreshes are faster, calculations stay accurate, and maintenance is painless. You will start by auditing the PBIX in Power BI Desktop, refactoring tables into a clean star schema, and rewriting any expensive DAX measures or calculated columns. Power Query steps must be consolidated and parameterised, with an eye toward incremental refresh and reliability through the on-premises gateway once everything is published to the Power BI Service workspace. Advanced DAX, solid M language skills, and a working knowledge of SQL objects are crucial because some changes may require tweaks to underlying views or stored procedures. Experience ...

    I need to turn raw treasury-trading deal data into clear, decision-ready performance reports. The core of the job is to build a repeatable process that reads my daily deal files, analyses them, and produces a set of Performance Reports covering three key metrics: • Return on Investment • Trading Volume • Profit & Loss Statement . RATES AND MORE The source files arrive in CSV/Excel straight from our treasury platform. I am comfortable sharing a sample dataset so you can map the fields, clean anomalies, and transform the numbers. Ideally the workflow is automated—SQL or Python for the heavy lifting and Excel, Power BI or Tableau for the final dashboards and printable summaries—but I am open to whichever stack you can justify as robust and maintainable....

    I’m working with several spreadsheets that combine both text and numerical fields and need them ready for reliable analysis. Everything will be handled in Microsoft Excel—which is my preferred environment—though familiarity with Google Sheets is always a plus should a quick hand-off be required. The raw files arrive in varying shapes, so your job is to bring uniformity and accuracy before I run deeper analytics. Specifically, I need you to: • Remove duplicates • Correct any obvious or hidden data entry errors • Standardize formatting across columns and rows (dates, numeric precision, text casing, etc.) Along the way you’ll also re-enter or adjust individual records where information is missing or inconsistent, keep clear notes of any assumption...
