Od 318,918 recenzí, klienti hodnotí našeho pracovníka SQL Developers 4.9 z 5 hvězd.I need a PowerBI specialist who can jump in right away and turn my Excel data into a polished, interactive report I can put directly in front of a customer. The focus is on visualising customer segments, so slicers, dynamic charts, and an intuitive layout are essential. You’ll be working solely with an Excel workbook (no SQL or cloud connectors for this phase), but the finished PBIX should be designed with best-practice modelling so it can scale if I add other sources later. I’ll provide the raw file and a brief on the key customer attributes I want highlighted; your job is to transform it into a clear, presentation-ready dashboard that refreshes cleanly when the data is updated. Deliverables • PowerBI (PBIX) file with data model, visuals, and measures • A sha...
I need hands-on help getting the most out of Oracle Fusion. I’m still defining the exact scope—Financials, Supply Chain, HCM, or a mix—so I’m open to your guidance on where to start and how best to tackle each module. The immediate priority is to evaluate my current setup, identify any gaps or mis-configurations, and outline a clear action plan that I can follow with or without ongoing assistance. Here’s what I’d like from you: • A brief assessment session (remote) to understand my environment, pain points, and goals • A written roadmap that covers recommended configuration tweaks, integrations, and any quick wins you spot • Optional follow-up services—implementation, customization, or ad-hoc troubleshooting—quoted separa...
I want to build a brand-new workflow automation solution that streamlines hospital bed management. The stack is fixed: Microsoft Power Apps for the interface, Power Automate for the logic, and Azure SQL as the single source of truth. The core idea Today our ward staff log availability, transfers, and discharge requests manually. I need that entire flow captured in a responsive Power App, then driven by automated approvals, notifications, and live occupancy updates tied directly to the Azure SQL tables. Key pieces I expect you to deliver • Azure SQL schema set up—or adapted from an existing one—to hold beds, patients, and status history • A Power Apps application (canvas or model-driven; your call) that lets staff admit, transfer, and discharge patients in just...
1. Context and Technical Requirements The project consists of migrating the entire product content of our current e-commerce site (PrestaShop) to our new Odoo Online instance (Enterprise version 19.0+e). Non-Negotiable Technical Constraints: Platform: The choice of the Odoo Online platform is non-negotiable. Any offer must be based on solid expertise in this environment.

I need a data-savvy professional to dive into our financial records, which live entirely inside company databases (no spreadsheets or CSV exports yet). The task is to pull the relevant tables, clean and shape the numbers, and then tell a clear story about what those numbers mean for the business. Once connected—SQL or any other database interface you prefer—please explore the data, surface noteworthy patterns, spot any irregularities, and summarise everything in an easy-to-share format. A short written report or slide deck accompanied by the queries, notebooks, or scripts you ran will be perfect; interactive visuals in Python, R, Power BI or Tableau are welcome if they help decision-makers see the picture faster. Accuracy, reproducibility, and concise insights are key. If thi...
I have a set of customer data that I need to interrogate quickly and accurately. I’m comfortable defining the business questions, but I want a specialist to translate those questions into tight SQL queries and elegant Excel formulas so I can draw clear insights without manual work-arounds. Here’s what I’m after: • Write and optimise SQL code that pulls the exact customer fields I specify, joins the relevant tables, and filters the data so I’m left with clean, analysis-ready output. • Build (or improve) Excel formulas—think lookups, SUMIFS, conditional logic, dynamic arrays or whatever you deem best—that let me slice the data and surface KPIs in a single click. • Deliver a brief walkthrough so I understand how the queries and formulas ...
Our entire sales history sits in a central database, and I need clear, actionable insights on two fronts: how each product line is performing and how those numbers break down by region. The raw tables are already structured, so you can dive straight in with SQL or your preferred data-wrangling tool, pull what you need, and surface the patterns that matter. Focus areas • Product performance: highlight best- and worst-selling items, growth rates over time, and any anomalies worth investigating. • Regional sales: compare territories, uncover seasonality, and flag regions that consistently over- or under-perform. I’m looking for a concise deliverable set—cleaned query output, well-labeled visualizations (Power BI, Tableau, or Python/Matplotlib are all fine), and a b...

I need a forensic-style review of one specific SKU in our Odoo database for the entire 2025 fiscal year. The physical count at year-end is far off what Odoo shows, and I want a clear, data-backed explanation of how the gap emerged. Please dig through every relevant layer of the Odoo audit trail: inventory adjustments, all incoming and outgoing shipments, every stock level change logged by the system, and any moves that might have originated from a virtual warehouse or similar location. I expect you to trace each transaction back to its source document, time-stamp, and user, highlight anything missing or edited, and flag signs of manual manipulation, back-dated entries, or misconfigured routes. Your final hand-off should include: • a concise reconciliation report that walks from th...

I want to dive into Oracle APEX for personal learning, so the goal is a clean, working install of the latest APEX release without running up costs. I’m not sure whether my current environment is ready for it, so part of the task is confirming—or, if needed, creating—a suitable Oracle database (XE, a lightweight Docker image, or an Oracle Cloud Free Tier instance all work for me as long as they stay cost-free). Once the database piece is settled, I’ll need the newest APEX version installed, configured, and reachable in a browser. Please add a simple workspace, an admin login, and a short checklist of what you did so I can reproduce the setup or tear it down and redo it later for practice. Deliverables • Database confirmed or installed and running • La...
I need a small utility—either a lightweight desktop app or a background service—that can connect to my existing SQL database and push data into clean, well-structured .qdb files. The tool must work from predefined queries; that is the core workflow I want. Once a query is executed the utility should automatically narrow the result set using two criteria I choose up front: data type and specific column values. The generated file must follow a consistent schema so a downstream system can consume it immediately. While optional .csv support is welcome, .qdb export is the priority. Connectivity via standard ODBC/JDBC, the ability to run on a schedule or by command-line/REST trigger, clear logging, and straightforward configuration (plain-text or simple UI) are all important for ...
I’m looking to put our scattered business information in order and would like a data specialist who can take ownership of the full management cycle—from bringing raw files together to handing back a clean, reliable dataset with clear reporting. Most of the information currently lives in spreadsheets, yet I’m open to smarter solutions such as a relational database, Power Query automations, or even a lightweight CRM if it keeps us organised. Here’s what will make the project a success for me: • An initial audit that reveals what data we have, what’s missing, and how best to structure it. • A consolidation plan that tackles duplicates, inconsistent formats, and validation rules before any major work begins. • Implementation of the agreed pro...
I’m kicking off a data-management initiative and need a seasoned professional to help turn scattered information into a reliable, well-structured asset. The first step will be a short discovery session where you review what I already have, flag obvious quality or consistency issues, and outline practical options for organizing and maintaining the data going forward. Once we agree on the approach, you’ll implement it end-to-end—setting up the storage environment, configuring validation rules, and documenting the workflow so it’s easy for me (or future staff) to update and extract information whenever needed. I’m flexible on the specific tools; cloud databases, spreadsheets, or a lightweight ETL solution are all on the table as long as they fit the scale of the...

Scope of work • Physically locate and tag all laptops, desktops, servers, networking gear and peripherals • Confirm and correct serial numbers, asset IDs, locations and user assignments in the software • Flag discrepancies or missing items immediately so we can investigate while you are still onsite • Capture any supporting photos and attach them to the asset records Deliverables 1. A fully updated, reconcil...
I need a Tableau workbook built right away that connects directly to our SQL databases and lets our analysts dig into the data on-the-fly. The core purpose is data exploration, so the dashboard should encourage quick filtering, drill-downs, and ad-hoc questioning rather than fixed executive summaries. You will receive read-only credentials to the SQL server plus a brief on the key tables and relationships. From there, I’m looking for an interactive dashboard (or set of sheets) that surfaces trends, outliers, and correlations in a way that invites further questioning. I haven’t locked in specific chart types yet, so feel free to choose the visuals—bar, line, heat map, or anything else—that best reveal insights. Because time is critical, please: • Build t...
