    I’m building the first release of my stock-trading platform, “Trade for Tomorrow,” and the immediate priority is to wire in reliable, ultra-low-latency market data for both the NYSE and NASDAQ.

    I need an experienced Siemens SIMATIC PCS 7 / WinCC engineer to build a read-only connector from an existing PCS 7 DCS system to an existing Excel MIS workbook. The plant already uses PCS 7/WinCC and the Excel workbook already contains formulas and a management dashboard. The goal is to automatically extract selected DCS values and populate only the approved Excel input cells without modifying plant-control logic. The freelancer should first review the actual PCS 7 setup and recommend the safest supported method, such as Siemens-generated Excel/CSV export, OPC UA/OPC DA, OpenPCS 7, Process Historian, WinCC archives, or another approved read-only interface. Scope includes: identify the correct PCS 7/WinCC data-access method; map approximately 50–100 required tags/parameters to Exc...

    For this project I need customer information that is currently scattered across several files merged, de-duplicated, and polished inside one master Excel or Google Sheets workbook. Once the sheet is tidy, every contact detail—name, phone, email, and address—has to be cross-checked against reliable web sources to make sure the data is accurate and up to date. When the verification step is done, the final workbook must follow my formatting guidelines (column order, header style, conditional colour coding). I will share a short style guide and a small sample so you can mirror the look and feel exactly. Deliverables • Cleaned and consolidated customer-info spreadsheet • Column-by-column log of any corrections made, including URLs or screenshots that confirm each u...

    My priority is to build and refine Microsoft Dynamics 365 Business Central through new AL objects, with the spotlight on custom tables and pages. These pages must support clean data entry, run their own validation, trigger custom workflows, and surface key metrics in dashboard-style reports. Beyond the UI layer, I need business logic that enforces bespoke validation rules and handles data integration processes so information moves reliably between internal modules and any external systems we connect later. Additional work will include, when required, adjusting RDLC or Word layouts for reports, extending posting and approval workflows, exposing data through APIs or web services, and tuning SQL for performance. Deliverables • AL code for tables, pages, and supporting codeunit...

    I’m putting together a showcase-worthy sales workbook for my Data Entry & Excel portfolio and need an expert touch. The dataset is retail-focused and will be a mix of records I supply and additional, realistic entries you create to round it out.

    I’m ramping up a set of data-heavy initiatives that all run on Microsoft Fabric, and I need an experienced hand who can jump in right away. The focus is pure data integration: designing and orchestrating Fabric pipelines, unifying data from disparate sources, and getting everything landed, cleaned, and ready for downstream consumers. While some reporting or admin work may pop up, the core responsibility is building robust, production-grade integration workflows inside Fabric itself—knowledge of only Power BI, SSIS, or generic ETL will not be enough. The engagement starts at a guaranteed 20 hours a week, with the real possibility of expanding to a full 40 as we move deeper into the roadmap. Work from home is perfectly fine, and for compliance and collaboration reasons I’m...

    I need a digital twin that zeroes-in on my building’s energy performance. Right now I only have partial data—BMS exports, sub-metering on a handful of panels, and monthly utility bills—so the model must be able to start with what’s available, validate any gaps, then scale as more sensors come online. Primary improvement targets: • Heating and cooling systems • Overall energy consumption The twin should connect to the existing BIM (Revit) files, ingest the live and historical data, and run calibrated simulations—EnergyPlus or an equivalent physics-based engine is fine—so I can visualise real-time KPIs and generate “what-if” scenarios for retrofit ideas. I’m interested in clear, actionable outputs such as predicted savings...

I need an offline solution—Excel-based is preferred, but I’m open to any lightweight desktop approach—that can pull the data from those three files, combine and clean it automatically, and then present the final results back in Excel across multiple worksheets.

Data in scope • Performance – I’ll supply spreadsheets with ratings, KPIs and other performance-related figures. • Attrition – separate files include exit dates, exit-interview summaries and job-satisfaction survey scores. Metrics and factors to highlight • Attrition trends appear alongside performance metrics in every view. • Job-satisfaction levels must be an explicit f...
