    I have four Excel workbooks that I now need housed in an existing MS Access database. None of the sheets are relational at the moment, so the job is a straight import and structure clean-up rather than designing complex links. Here’s what I need from you: • Import 4 existing Excel Files into 4 tables in an existing MS Access DB (.ACCB) • Add a few basic queries so I can filter, sort and export the data quickly. • Delete bad data and duplicates The project is to be done in .net with WPF user interface. Once complete, send me the .accdb file and the brief how-to notes—that’s it. If something in the data suggests a better structure, feel free to flag it before you proceed; otherwise, a clean one-to-one migration is all I’m after.

    I have a single PDF that holds several hundred pages of ledger entries recorded over multiple years. Because of irregular spacing, merged columns, and stray narrative comments, the file can’t be queried, reconciled, or audited in its current form. Your task is to turn every line in that PDF into a structured dataset that I can drop straight into accounting software or run analysis on. Scope of work • Parse the PDF and capture every transaction—including dates, descriptions, reference numbers, debit / credit amounts, and running balances—without loss of detail. • Correct inconsistent number formats (e.g., minus signs, comma placement, mixed currencies) and standardise dates to ISO. • Isolate any narrative comments so they appear in a separate &ldqu...

    I have several production PL SQL scripts that are starting to show their age: execution times have crept up and they are consuming more CPU and memory than I am comfortable with. The primary focus of this project is therefore PLSQL itself, not application-level logic or UI work. What I need from you is a careful optimisation of the existing codebase. The goal is two-fold—raise overall performance and cut back on resource usage—without changing the functional output in any way. You will be working with code that is already in use, so a light-touch, incremental approach that can be verified against current results is essential. Deliverables I expect • Revised PL SQL scripts ready for drop-in replacement • A short before/after performance summary (timings and resourc...

    I need a reliable freelancer to pull a blend of text and numerical information from several specified online sources and enter it directly into our live database. You will receive secure database access, complete field guidelines, and a short orientation video so you understand the required structure before you begin. Accuracy is critical; each record must match the formatting rules I provide and all values need to be double-checked for consistency. You should already be comfortable working inside a web-based database interface or with SQL tools, and able to keep a clear audit trail of changes. When the assignment is complete I’m expecting the database to be fully populated, error-free, and ready for immediate reporting use.

    I’m working with several spreadsheets that combine both text and numerical fields and need them ready for reliable analysis. Everything will be handled in Microsoft Excel—which is my preferred environment—though familiarity with Google Sheets is always a plus should a quick hand-off be required.

Specifically, I need you to: • Remove duplicates • Correct any obvious or hidden data entry errors • Standardize formatting across columns and rows (dates, numeric precision, text casing, etc.) Along the way you’ll also re-enter or adjust individual records where information is missing or inconsistent, keep clear notes of any assumption...

    I have an in-house VB.NET application backed by SQL Server 2008 R2 that currently schedules four 6-hour shifts per day. Operational changes now require three 8-hour shifts instead.

Because the scheduling and allocation algorithms drive time-sensitive workflows, any adjustment must keep existing calculation accuracy intact.

    I have several raw datasets that need to be transformed into clear insights I can act on. Because the data spans different business areas, I’m open to whichever analytical approach—descriptive, predictive, or prescriptive—you believe will unlock the most value. Here’s what I’d like to walk away with: • A clean, well-structured dataset that documents every transformation step • An analysis that highlights key patterns, outliers, and actionable trends • Visualisations and a brief write-up summarising findings, assumptions, and recommended next steps Please outline the method you would apply, the software stack you’d choose, and any clarifying questions you have about the data’s shape or source.

    Hostinger PHP & Backup Setup

    I have a small GPS-tracker website that is already coded in PHP and MySQL; now I need it running smoothly on my Hostinger account. The priority is to get the hosting environment configured, make sure PHP and phpMyAdmin are accessible, then organise a clean routine for handling my database files. Here’s what I expect: • Move or recreate the current site on Hostinger, adjusting PHP versions or extensions if needed so every tracker feature works. • Set up a simple, reliable path in phpMyAdmin (or a tool you recommend) so I can manually upload and download my .sql backups whenever I want—no automated schedule is required, just a clear step-by-step flow I can repeat. • Confirm that each manual restore correctly repopulates the database and leaves the live site...

    For the next round of hiring I want an accomplished Senior Data Engineer to sit in on our technical interviews for roughly two hours each day. The role is purely evaluative: you will craft probing questions, join live video calls, and quickly score each candidate’s depth of knowledge across Python, Scala and SQL. Our stack centres on Azure and Databricks, so practical insight into large-scale Spark/PySpark jobs, data-model design, ETL orchestration and cloud performance tuning is essential. Candidates frequently discuss streaming, optimisation strategies and modern AI/ML add-ons, so any hands-on exposure to libraries such as PyTorch, NumPy, SciPy or TensorFlow will help you challenge them at the right level, though it is not mandatory. Availability is limited to two focused hou...
