Modelare de date Jobs

I have several Excel workbooks that need to be transformed into clear, interactive visuals built in Power BI. The priority is comparative analysis: I want end-users to see how figures stack up against one another across products, time periods, or any other relevant dimension we identify together. At this stage I’m concentrating purely on visual exploration rather than a full narrative report or enterprise-wide dashboard, though I appreciate designs that could scale in that direction later. You will receive the raw Excel files along with a brief that highlights the main metrics to compare. I expect you to model the data inside Power BI, choose the most effective visual types, and apply slicers or drill-through where they add value. Please keep the visuals clean, performance-friendly,...

I need a fully-interactive marketing performance dashboard built in Power BI that lets me slice and explore data by channel, campaign, lead source, and region. The core data set includes social media, email campaigns, and paid search; from it I want to surface four headline KPIs—Total Revenue, Total Budget, Conversion Count, and ROI %—and be able to drill down quickly with dynamic filters, date-range controls, and campaign-level selectors. The visual layer should rely on clear, insightful charts and graphs: • side-by-side budget-versus-revenue comparisons for each channel • trend lines that react instantly when the date slider is adjusted • conversion funnels or stacked visuals that reveal strengths and gaps across regions Behind the visuals, please set u...

I will hand over a clean dataset that tracks our globalization work; it includes progress metrics, current status markers and a field we label “DVA9” for one specific language group. I need you to turn that raw information into a single-page, visually striking report built in Looker (Looker Studio or Looker BI). The page should spotlight overall text-localization progress, surface any issues you uncover and make the narrative immediately clear to an executive reader. Use the platform’s native charting, colour-coding and drill-through features so stakeholders can see at a glance where we stand and where problems still sit. Keep the layout crisp—headlines, key KPIs, and a compact visual timeline or bar that shows completion versus open issues. When possible, struct...

I need a comprehensive technical-and-functional blueprint for a new specialized digital platform. To ground every recommendation in real-world evidence, you will first study competitor platforms as well as several user-nominated platforms that my team will share. Drawing from that analysis, you will then produce a single, well-structured document that details the platform’s architecture, key modules, data flows, integration points, and any compliance or scalability considerations. The final blueprint should read like a roadmap that an engineering team could pick up and start building from. Clear diagrams, precise feature descriptions, and rationale for each technology choice are essential. Your background in technical writing and software documentation—especially where technic...

I need a set of automated dashboards in Google Sheets that continuously pulls data from our recurring CSV exports and turns it into a live view of company performance. The two figures I must see at a glance are Revenue and Net Profit, with the option to slice by product line and date once the basics are stable. Here is what the finished workbook should let me do: • Drop the latest CSVs into Drive and watch the data model update without manual copy-pasting. • View clean, interactive charts and tables that refresh on schedule or at the click of a button. • Export or share the P&L dashboard with teammates while keeping formulas locked down. Please build whichever mix of formulas, pivot tables, named ranges, or Apps Script you feel is best to keep refresh times f...

I need an engineer who already works comfortably with the MZ Automation (openIEC61850) library to build a complete, Edition 2.1–compliant SCL file for one of our Smart Grid systems.

I’m refreshing my GitHub profile for upcoming university applications and I need a concise, well-architected Django backend that illustrates how I approach data modelling, API design and clean code. Tech stack is fixed: Python 3.x with Django (latest LTS). Because this is a portfolio piece, clarity, documentation and sensible project structure matter more than production-grade scaling or DevOps extras. Scope of the system The app should let authenticated users track items in and out of stock and generate simple reports. I expect models for items, categories and basic stock movements, JWT or session-based authentication, and a small reporting module summarising current inventory levels and movement history. Deliverables • Django project and apps organised with reusable, ...

I need a custom Deneb visual in Power BI. The data will live entirely inside the visual specification—no Excel sheets, databases, or APIs to connect—so you can reference it directly as inline arrays within the Vega-Lite JSON. I've attached a mockup of how I need this visual to look, I've also attached some Vega Lite code which I've attempted to make work but it is a starting point, the code also contains an in-line dataset

I have an existing analytics initiative that now needs a dedicated Redshift-based warehouse. The core objective is to design and implement a robust schema in Amazon Redshift, then ingest data coming from three different sources—our operational SQL databases, a set of RESTful APIs, and periodic flat-file drops in CSV or JSON. Here is what I’m aiming for: • A well-structured Redshift warehouse (star or snowflake schema, whichever is most appropriate) built to scale and documented clearly. • Reliable, automated ingestion pipelines for each source type. For SQL we currently use PostgreSQL and MySQL; for APIs the payloads are mostly JSON; the flat files live in S3. • Transformations that standardise data types, handle slowly changing dimensions, and enforce dat...

Our organisation’s data assets sit in multiple platforms and formats, and the absence of a common language is starting to hinder everything from analytics to audit response times. I want to put in place a unified metadata management framework that improves governance across the board, with a special emphasis on meeting strict Compliance requirements. The scope covers information architecture, controlled vocabularies, and an enterprise-wide taxonomy that standardises terminology between systems. The work will culminate in a reusable model that makes stewardship activities—classification, retention, lineage tracking—far easier and more defensible. Key deliverables • A logical and physical data taxonomy covering all major subject areas • Controlled vocabu...

I need a Google Cloud / BigQuery specialist to stand up an end-to-end, webhook-driven data ingestion pipeline running in our production environment. When our external form system fires a webhook, your Cloud Function (or equivalent service) should capture the JSON payload, write the untouched record to a raw BigQuery table, then immediately process it. The processing step must • parse any nested JSON, • flatten and clean each answer field, • split the results into two purpose-built reporting tables, and • guarantee idempotency through a hashing technique that blocks duplicates. All components have to be secure, version-controlled, and able to scale with traffic spikes. This is strictly a backend/data-engineering job—no UI work is involved.
