    I need a Microsoft SQL Server specialist who can take stacks of paper‐based records, design the appropriate tables, and manually key every field into a clean, well-structured database. Once the information is in place, I want meaningful statistical insight extracted—basic descriptive stats, variance and correlation figures, and any notable outliers that should be flagged. To succeed you will be comfortable with SQL Server Management Studio and T-SQL for schema design, indexing and data validation rules that prevent transcription errors. After entry, apply your preferred statistics toolkit (native SQL functions or an external package you connect to the database) to run the agreed analyses and return concise results.

    Sorry, I had to create a new project because the content has changed so much. We have a freshly configured root server with a fresh installation of BigBlueButton on it. An unsuccessful initial migration from Rocket LMS is now to be carried out on this server and, where necessary, fully configured (logo, colour schemes, payment system, etc.). The installed BigBlueButton on the root server also have to be configured to be intergrated completely with the LMS. Once everything is running smoothly, SuiteCRM should be installed and hold a short session to guide our staff through the new environment: how to launch BBB rooms, update branding assets and ensure that future updates will not overwrite the customised work. In general, the following tasks need to be carried out: • Migration fro...

    I need a proven strategy to move more than 10 TB of mixed-type data—media assets, databases (primarily MSSQL dumps) and a variety of project files—across our WAN as quickly and safely as possible. The current link struggles with long round-trip times and occasional packet loss, so every transfer drags on for days and sometimes fails outright. My aim is threefold: slash the overall transfer window, eliminate checksum mismatches or corrupt segments, and lighten the ongoing load on the network while these moves are in progress. I am open to any combination of protocol tuning, compression, data deduplication, forward-error correction, WAN acceleration appliances, or cloud relay services—as long as the end result delivers measurable improvements.

    Our main database is already running on PostgreSQL 13 (anything in the “12.x or higher” family), and I need an experienced DBA to step in and tighten two things: First, Database optimization. The work includes reviewing current configuration parameters, checking execution plans, tuning indexes, and suggesting any schema changes that will noticeably reduce latency under peak load. If extensions (pg_stat_statements, auto_explain, etc.) should be enabled or configuration values (shared_buffers, work_mem, effective_cache_size and friends) adjusted, please make those recommendations backed by data. Second, Backup and recovery. I want a clear, scripted process—preferably with pg_dump and/or a modern tool such as pgBackRest or Barman—that covers daily backups, point-in-t...

    I have a large set of customer information stored in a database, and I need it cleaned, structured, and exported into professional-looking spreadsheets so my team can work with it easily. All of the data is already digital—no paper scanning involved—but the current tables are messy, contain duplicates, and use inconsistent field names. You’ll connect to the database directly (whether it’s MySQL, PostgreSQL, or Microsoft SQL Server—the exact engine can be confirmed once we start) and pull every customer record. From there, I’m expecting: • One master Excel or CSV file with clear, human-readable headers • Removal of duplicates and obvious data entry errors • Consistent formatting for dates, phone numbers, and addresses • A brief...
