Senior / Staff Data & AI Engineer — Freelance Engagement: Freelance / Contract Work Arrangement: Remote Level: Senior or Staff Duration: Project-based, with potential for ongoing work About the Project We are looking for an experienced Senior or Staff Data & AI Engineer to help design, build, and productionize a data-intensive system involving cloud data platforms, machine learning, and AI-powered workflows. This is not a task for someone who only creates notebooks, writes basic ETL scripts, or connects an API to an existing application. We need someone who can understand the full system, make sound architectural decisions, implement the difficult parts, and leave behind a maintainable production solution. You should be comfortable working independently, explaining techn...

I’m getting ready for interviews that revolve around Power BI, advanced Excel work, and the specific challenges that come with Logistics data. My current Power BI skill level is solidly intermediate, so I don’t need a ground-up tutorial—I need someone who can push me to the next level, tighten any weak spots, and simulate the kinds of questions and practical tasks recruiters will throw at me. Here’s what I’m looking for: • Focus areas: deep-dive Power BI functionalities (DAX optimisation, data modeling, interactive visuals, and performance tuning), Excel advanced features (Power Query, complex formulas, VBA/macros if relevant), and end-to-end Logistics data analysis scenarios (inventory turns, route optimisation, freight cost KPIs, OTIF calculations). ...

I’m rebuilding the backbone of my application and need an experienced backend specialist to take ownership of the database layer on Google Cloud. The project centres on cloud-based data management rather than general API or server work, so your focus will be schema design, provisioning, and optimisation on the Google Cloud ecosystem. Here’s what I’m after: • Analyse my current data requirements and model an efficient, scalable structure. • Create and provision the chosen Google Cloud database service (Cloud SQL, Firestore or another you recommend) with best-practice security settings. • Configure automated backups, monitoring and role-based access so the environment is production-ready. • Deliver clear documentation covering the schema, deployme...

I have an internal dashboard that uses AI to generate automatic email replies. It works, but it’s starting to fall behind our needs. The main goal is to boost the accuracy of each suggested response while making the interface feel smoother for everyday users. Accuracy updates • Refine keyword-matching so the system chooses the right intent even in edge-case phrasing. • Incorporate stronger natural-language-processing techniques to handle varied sentence structures and tone. • Refresh or retrain the underlying data models; I’ll provide sample email logs for you to fine-tune on. Interface refinement Right now the layout is functional but clunky. I want the overall user experience to feel intuitive—fewer clicks from draft to send, clearer confidenc...

I am looking for an experienced Python and Machine Learning developer to build an AI-based bias correction model for WRF 2-meter temperature (T2m) forecasts. Historical data will include WRF forecasts and observed temperatures from weather stations . The goal is to train a model to predict forecast bias and produce corrected temperature forecasts.

The goal is to turn raw accounting exports into a clear Management Information System inside Microsoft Excel. The workbook must display financial data only, with live views on Revenue & Expenses, Profit Margins, and Cash Flow. I will supply the source files (CSV and XLSX). Your job is to design the data model, automate the refresh, and present the numbers through clean charts, pivot tables, slicers, and conditional formatting so that anyone on the team can spot trends in seconds. Power Query or VBA is welcome if they simplify the workflow, but the final file has to stay fully portable in standard desktop Excel. Deliverables • One .xlsx file containing the dashboard and underlying data model • Simple “Data Refresh” button or documented refresh steps &bull...

I need an experienced Power BI specialist who can dive straight into an urgent KPI dashboard build for our Bedford-based business. The model must pull live and historical data from three different sources—Excel files stored in SharePoint, our on-premise SQL databases, and several Online APIs—and blend them into a single, well-structured data model. The core story the dashboard must tell is operational efficiency: utilisation rates, throughput times, downtime causes, cost per unit, and any other DAX measures you know will help management spot bottlenecks quickly. Alongside that operational narrative I also want space for two high-level sales indicators—total revenue and sales growth rate—so leadership can see in one view how internal performance is affecting topline...
