    I’m onboarding a senior Oracle EPM Solution Architect (18 + years) for a high-visibility programme that starts on-site in the Middle East for roughly four to five months before switching to offshore delivery. The contract is ready to begin immediately (ideally within the next 15 days), and a CA, ICWA or CMA qualification is non-negotiable. The work centres on defining and governing the overall EPM architecture, shaping scalable financial models and driving end-to-end implementations across FCCS/HFM and EPBCS. Expect deep hands-on time with ASO/BSO cubes, complex calc scripts, Groovy, PowerShell, Python and EPM Automate, plus REST API–driven data integrations that must remain rock-solid under GAAP and IFRS requirements.

    I need a small utility or script that pulls our Sales data from a shared FileMaker Pro file and drops them straight into a pre-existing Excel workbook. The process has to run twice a day—once in the morning and againat 7pm—without anyone clicking a button. No data cleansing or re-formatting is required; I just want the exact export that FileMaker produces to appear in Excel, ready for further analysis. You’re free to choose the most reliable route—FileMaker Server schedules, an ODBC connection, a FileMaker script coupled with Power Automate, even a lightweight VBA or Python bridge—so long as it works unattended on Windows and can be quickly adjusted if the report layout changes.

    I need an experienced Xero bookkeeper to step straight into my live file and keep the day-to-day accounts in perfect order. The core of the job is to handle invoicing and expenses, reconcile the daily bank feeds, and turn the numbers into clear basic reports that I can rely on for decision-making. Although the organisation is already on Xero, the setup needs work.

    I have an existing Excel workbook that currently relies on manual submissions. All the figures we need already live in a SQL Server database; they simply have to appear in the correct cells of the form and then trigger the usual calculations and formatting the sheet already performs. Here is what I need from you: connect Excel to SQL Server, pull the required numeric fields, map them to the form’s input range, and set the process to refresh on demand (button or scheduled refresh—whichever is cleaner).

    I am building an intraday front- and back-office reconciliation intelligence platform that surfaces trade breaks within minutes instead of waiting for the usual end-of-day batch reports. The goal is twofold: first, to highlight exceptions in near real-time so operations teams can act while a position is still fresh; second, to recognise when multiple apparent breaks share one underlying root-cause and roll those into a single, actionable incident. Integration with SimCorp Dimension is central: the system will consume positions, cash ledgers, transactions, and instrument reference data through its published REST/OpenAPI services and supporting data-access interfaces, on both scheduled and event-driven cadences.
