    I have a set of digital files that contain purely numerical information, and I need every figure transferred accurately into my existing database. You will be working directly with the database layer—so familiarity with typical SQL interfaces or import tools is essential. The files are already in clean digital form; your task is to extract each number, verify it matches the source, and insert it into the correct tables and fields. Once the upload is complete, a quick cross-check against the originals will confirm that no values were missed or altered. Deliverable • A fully populated database reflecting 100 % of the numbers in the supplied files, with spot-check verification passed.

    I need to turn historical patient-record data into a reliable model that predicts individual outcomes and flags high-risk cases early. The raw material is a sizeable set of anonymised electronic health records: demographics, vitals, lab results, admission notes, discharge summaries—typical structured tables mixed with a handful of free-text fields that have already been de-identified. Here is what I’m after: • A clean, reproducible pipeline in Python and SQL that pulls the records, handles missing values, encodes categorical variables, and outputs a model-ready dataset. • One or more predictive models built in scikit-learn (feel free to benchmark XGBoost or similar) together with well-explained feature importance.

    This project centers on a brand-new MS SQL Server CLR-based User Defined Function that performs format-preserving encryption (tokenization) of Personal Identifiable Information. The primary goal of this engagement is to validate that the CLR UDF architecture meets the required throughput target. The cryptographic implementation may use an existing FF1/FF3-1 library or a lightweight placeholder — what must be proven is that the SQL Server CLR layer can sustain the expected load at scale. Every line will be written from scratch and staged in our Development environment. Scope • Implement FF1 and FF3-1 per NIST SP 800-38G in C#. An existing open-source library is acceptable provided it is fully managed and compatible with SQL CLR deployment. • Wrap the algorithms in a MS ...

    I have bike-sales data sitting in a SQL Server database and I need a clear, insight-driven view of what is really happening in the business. You will start by writing well-structured SQL—JOINs, GROUP BYs, subqueries, the works—to pull everything together. From that result set, build an interactive Power BI dashboard that surfaces the three core KPIs I rely on: Revenue, Sales Volume, and Profit Margin. Because our immediate focus is growth in Asia, the visual story must spotlight that region’s performance while still letting me drill into individual models to see which bikes are driving results. The finished dashboard should help my team make faster inventory and demand-forecasting decisions, so usability and speed matter as much as visual polish. Deliverables I expe...

Here is the flow I have in mind: every night a batch job connects to our SQL databases and a couple of internal APIs, pulls the required product data, and writes a clean, report-ready snapshot into a staging table (or tables) that you design. As soon as a user loads the dashboard, individual widgets fire the SQL you attach to them, read from that snapshot, then hand the results to a rendering layer that turns the numbers into the appropriate visual—bar graph, doughnut, pie chart, line graph, or whatever makes the most sense for that data point.

    I’m putting together a small, fully-responsive website in React.js and want it executed with a clean, minimalist aesthetic. The site will have four core pages—Home, About, Services and Contact—wired up with smooth navigation and lightning-fast load times. I don’t have fixed brand colours yet, so you’re free to suggest a palette that fits a minimalist look and reads well on both light and dark devices. Whether you prefer Bootstrap or Tailwind CSS is up to you; what matters is that the final UI feels modern, uncluttered and scales perfectly from mobile through desktop. Key things I’ll be reviewing: • React component structure that’s easy to maintain • Clear routing between the four pages • Fully responsive layouts and media...

    I’m brand-new to Tableau and need a patient, knowledgeable tutor to guide me through the fundamentals in live, one-to-one sessions. My focus areas are data visualization basics, connecting to data sources, and dashboard creation. I already have specific work projects in mind, so each lesson should be hands-on and anchored to my real datasets and KPIs. Here’s how I picture the engagement: • Meet via Zoom or Google Meet, with screen-sharing and session recordings so I can review the material later. • A short learning roadmap that gets me from “Beginner” to confidently importing data, choosing the right chart types, and assembling interactive dashboards. • Practical homework or mini-assignments between calls and the option to message you for quick ...

    I built our freight-forwarding solution in .NET with an MS SQL back end, covering everything from enquiries and quotations through to job management, House BL printing, and P&L reporting. The only missing piece is a seamless bridge to external accounting software—this is where I need your expertise. What I want • Direct integration between my freight-forwarding database and a well-known accounting package (e.g., Tally, QuickBooks, Xero or a similar platform you can propose). • Automatic transfer of all financial events we already capture—sales invoices, supplier bills, receivables, payables, and cost allocations—so the books stay in sync without duplicate entry. • Bi-directional status updates: if an invoice is paid or a journal is adjusted in th...

    Tengo un conjunto mixto de información: tablas y bases de datos, pero también imágenes y documentos que se han digitalizado. Necesito que un especialista realice una limpieza exhaustiva sobre ambos tipos de datos con el objetivo específico de corregir errores —desde valores mal ingresados en celdas hasta fechas, nombres o etiquetas mal reconocidas en los archivos no estructurados. Qué espero recibir • Versión depurada de cada set estructurado (CSV, Excel o base de datos) con los errores corregidos. • Archivos no estructurados revisados y, cuando sea posible, con metadatos actualizados o un registro de cambios aplicados. • Un informe breve que resuma los errores detectados, el criterio utilizado para corregirlos y las herra...
