I’m rebuilding the backbone of my application and need an experienced backend specialist to take ownership of the database layer on Google Cloud. The project centres on cloud-based data management rather than general API or server work, so your focus will be schema design, provisioning, and optimisation on the Google Cloud ecosystem. Here’s what I’m after: • Analyse my current data requirements and model an efficient, scalable structure. • Create and provision the chosen Google Cloud database service (Cloud SQL, Firestore or another you recommend) with best-practice security settings. • Configure automated backups, monitoring and role-based access so the environment is production-ready. • Deliver clear documentation covering the schema, deployme...

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...

We have Oracle and MS-SQL environments that need expert support, and for compliance purposes the work must be performed by someone who is physically located in Canada.

Ongoing operational support – Handle day-to-day administration, performance tuning, security patching and capacity planning. – Document every change clearly so our internal team can trace what was done and why. Integration assistance for active projects – Our developers are building Web and...

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...

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...

Our production systems run on a dedicated PostgreSQL database server that needs ongoing, professional management to keep performance high and downtime at zero. I need an experienced PostgreSQL administrator to take charge of routine upkeep, monitoring, and rapid incident response so the team can stay focused on product development. Scope of work You’ll handle version updates, configure and verify automated backups, watch key metrics, fine-tune queries and indexes when bottlenecks appear, and strengthen security by keeping roles, permissions, and network rules tight. The server is Linux-based and accessed via SSH; fluency with psql, pgAdmin, and common monitoring stacks (Prometheus, Grafana, or similar) will make the job straightforward.

I’m committing the next eight weeks to sharpening my SQL and Excel skills and I’d like you to steer the process. I already work comfortably at an intermediate level, but I’m still spending far too long turning raw data into clear, compelling visuals. My goal is to leave this programme able to move from question to insight quickly—writing tidy, well-structured SQL queries and translating the results into polished dashboards and charts inside Excel (and, where it makes sense, Power BI). Here’s how I picture our collaboration: • A structured learning path that steadily raises the bar each week, mixing short theory explanations with hands-on exercises drawn from real business scenarios. • Screen-sharing or paired-coding sessions where you watch me wo...

I need an experienced data specialist to take an old-format XLS file and move it into my SQL database after applying several transformations. The raw worksheet contains multiple sheets of mixed data types, so before anything is loaded I’ll need column mapping, type casting, and a few calculated fields added (we can review the exact logic together). Once the transformation rules are approved, please import everything into the live SQL instance and provide: • A repeatable script or ETL package (Python, SSIS, or similar) • A short README explaining how to rerun the job and tweak the mappings • Verification that every record landed in the correct table with accurate data types and relationships I’ll supply the sample XLS, the current SQL schema, and the t...
