Database Development Jobs

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. Deliverables • D...

Research should identify relevant local/regional decision-makers in construction, operations, project management, materials, purchasing and related functions. Quality and verification are more important than quantity. The complete...

I have a MySQL database that needs a set of well-structured, performant SELECT statements built with precise Boolean logic. The goal is to retrieve complex, multi-condition result sets in a single call rather than piecing data together in application code. You will be working only on read operations—no inserts or updates—so efficiency and clarity of each query are critical. The tables are already indexed, but I welcome recommendations if you spot obvious improvements that would speed up AND / OR combinations, NOT clauses, nested conditions, or full-text searches. Once the queries are finished, I need a short explanation of the logic behind each one so future maintenance is straightforward. Deliverables I expect: • SQL files (or a single file) containing the final SELEC...

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’m a complete beginner to data engineering and want a structured, guided path that quickly gets me comfortable with real-world workflows. My first priority is solid data modeling, but I’d like each concept tied directly to hands-on practice as well as the “why” behind it, so theory and application move together. The stack I need to master is SQL, dbt, Snowflake, and Fivetran. A typical session might start with designing a dimensional model, move into building that model in Snowflake, automate the ELT with Fivetran, and finish by transforming the data with dbt—all committed to Git so best practices stick from day one. I learn fastest by doing, so please be ready to: • Walk through short, focused explanations, then immediately switch to screen-sha...

I have a list of online sources that contain both narrative text and numeric figures, and I need every one of those details captured in a single, well-structured Excel workbook. The job begins with careful data entry: copy each text field, metric, date, or code exactly as it appears on the web page and paste (or import) it into the template I will provide. Because the information is mixed data—words and numbers side by side—consistent formatting, proper column alignment, and vigilant error-checking are essential. Once the raw information is entered, the spreadsheet has to become an analysis tool. Please set up the formulas that calculate totals, averages, and any other basic statistics we agree on, then create clear charts or graphs that visualise the key results. Think of it ...
