    I need a seasoned SAP consultant who can jump on a short, 2-to-3-hour screen-share session with me and show, step by step, how to pull the accounting-focused order data I’m after and get it out of the system in a portable file. Context • My system records purchase-order activity in an accounting back-end rather than the usual MM, SRM, or Ariba paths, so you’ll need to be comfortable navigating FI/CO tables, custom Z-tables, or any cross-module links that might store the numbers. • The main objective is to isolate all fields tied to these orders (header and line items, posting details, values, partner data, timestamps, etc.) and make sure nothing is missed. What I’d like from you during the call 1. Identify the tables, transactions, or CDS views that actu...

    I have a production-support ticket that I need to close quickly.

Your task is to jump into my Azure environment, pinpoint the root cause, and get the pipeline running cleanly end-to-end. What you’ll tackle • Debug the pipeline activity that integrates with the SQL script. • Tune or rewrite the script so it runs efficiently without timing out or over-consuming resources. • Validate by triggering the pipeline in Production and showing a successful, performant run.

    My SQL client reaches the database through an ngrok tunnel on a Windows host. The tunnel reports a successful connection, yet the moment the client tries to talk to the server it comes back with an “access denied” message and drops. I selected “sql service” as the server type because ngrok is sitting in front of the actual SQL service; the database itself is on Windows and exposed on the usual port. I need someone who knows ngrok’s authtoken setup, TCP tunnels, SQL authentication and Windows-side firewall or MSSQL configuration well enough to spot what I have missed and get the handshake to complete.

    I need an end-to-end solution that lets our users open a React-based dashboard each morning and instantly see fresh, role-specific metrics. 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. Each widget also checks the visitor’s role and shows or hides itself accordingly, so our sa...

    I need an experienced VB developer to add a robust report-generation module to my existing application. The core requirement is the ability to build reports whose layout can change at runtime—groupings, columns, charts, and even page orientation must adapt to user selections rather than following a fixed template. You will work with the current VB codebase, hook into my SQL Server data layer, then expose a clean way for end-users to design, save, and export their own reports (PDF and Excel are the primary targets). Crystal Reports or ActiveReports experience is a plus, though I am open to whatever reporting engine you feel gives the greatest flexibility in Visual Basic. Acceptance criteria • Users can choose any data fields and instantly preview the resulting report. &...

I need the whole dataset blended, modelled, and surfaced in Power BI as a single, lightning-fast dashboard my exec team can open and immediately understand. Scope of work • Connect directly to the SQL database and configure an automated import for the monthly CSVs. • Build an efficient star-schema model in Power Query and DAX so refreshes remain snappy. • Create intuitive Bar Charts, Line Graphs, and Pie Charts that highlight the three critical metrics we track: Total Sales, Sales by Region, and Top Products. • Publish the report to the Power BI Service and set up a reliable weekly scheduled refresh (no manual steps). • Optimise vi...

    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. If you’re comfortable manipulating numeric datasets and working inside a live dat...

    I'm looking for an experienced recruiter or sourcer to help me find strong candidates for a Financial Planning & Analysis role. The ideal candidates have FP&A/finance/analytics backgrounds and LTV/CAC modeling experience. Before committing to the full project, I'd like you to send me 1–3 sample candidates at no cost so I can confirm the quality of your work. These platforms attract many unqualified applicants who can't actually complete the job, so I want to be sure before hiring you to find me up to 30 high-quality candidates. If the sample candidates are strong, we'll move forward with the full, paid engagement.

    I’m looking for an experienced full-stack AI/ML developer who can dedicate part-time hours during Central Time. Your immediate focus will be hands-on data analysis of well-structured datasets that live in our relational databases and spreadsheets. You’ll be expected to explore, clean, and transform this data in Python using pandas, then turn it into clear insights or prototype models that the rest of the team can act on. Because we operate in CST, I’ll need you available for regular check-ins, code reviews, and the occasional real-time pair-session. Fluent English is a must—we move quickly and rely on concise discussion to scope experiments and share findings with non-technical stakeholders. Typical workflow • Pull data from our existing SQL sources or flat...
