I keep seeing high RAM utilisation on both Oracle Linux and Red Hat Enterprise Linux servers and I want to understand, in depth, what is really happening inside the memory subsystem. More than a quick fix, I need a knowledgeable administrator who can walk me through each layer—kernel, user space, buffers, cache, swap—so I can read the numbers with confidence and spot the true culprits when usage spikes. Here is what I expect from our collaboration: • A live, step-by-step session (or series) where we run commands such as free, top, vmstat, sar and others you recommend, interpret every column, and relate the output to the kernel’s behaviour. • Practical explanations of how Oracle Linux and RHEL may differ in their memory reporting and tuning parameters. &bull...

I need an experienced Comfy specialist to take us from a blank server to a fully functioning environment my team can rely on every day. The first priority is a clean installation and initial configuration: database, user roles, security settings, and any recommended performance tweaks. Once it is running smoothly, I’d like you to walk us through the platform’s more advanced, custom-feature workflow so we can tailor it to our internal processes. We have not yet decided whether the platform will need to hook into other tools, so I’ll look to you for advice on what’s possible and the best timing for any integrations. After setup, please deliver an advanced training session (remote is fine) that demonstrates how to extend or adjust those custom features, plus written ...

Hi! I am looking to upgrade my current sales dashboard. I am looking for a Data Specialist who I can learn from and who can propose the best solution for my needs. Data will come from CSV files. I need a place where I can import that data to. I would like the dashboard to be as detailed as possible showing multiple KPIs, graphs, and correlations between the various data. Once setup, I would like it to be fairly simple to import new data, and modify the dashboard as needed over time. I would like this setup to be fully offline and local. My current thoughts are Metabase + SQLite. However I am open to other solutions and recommendations. I will be able to provide an example of the CSV during discussion to see how and what we can achieve with the data. I am looking for an individual who...

I need an experienced Microsoft Fabric administrator to keep several workspaces healthy and up-to-date. The core of the engagement is ongoing general maintenance, with three recurring duties at its heart: • Regular backups of every workspace, stored securely and verified for integrity • Security checks that review permissions, access policies, and audit logs • Version updates to ensure we are running the latest stable features without disrupting service If you can also lend a hand with occasional troubleshooting or performance tuning when it makes sense, that would be a welcome bonus, but the immediate priority is the steady rhythm of maintenance tasks above. Please outline the process and tooling you normally use for Fabric backups, security hardening, and update...

I’m setting up a central repository where each of my subscribed clients—schools, companies, public bodies and similar organisations—can log in over the internet to view, upload and download their own estate-related and compliance documents such as surveys, inspection reports and certificates.

I have a backlog of financial figures that must be transferred accurately into working spreadsheets and then reflected in our existing SQL database. The spreadsheets will be the primary source, so precision in every cell—dates, currency formats, formulas, and cross-sheet references—is essential before the data is pushed to the database. You will receive scanned source documents, the current Excel template, and credentials to a staging schema in our SQL environment. Once each spreadsheet is complete and vetted for errors, the corresponding tables in SQL need to be updated so that our reporting dashboards stay in sync. Deliverables • Completed Excel workbook with all financial data correctly entered and formatted • SQL script (or direct upload) that mirrors the sp...

My WordPress site went offline after I updated the database host setting and I’m now getting a connection error. Everything else—database name and user credentials—remained untouched, so I’m certain the issue is tied to that host change.

I have several disparate sources holding our inventory information and I want it all pulled together into one clean, well-structured Microsoft SQL Server database file. The job is straightforward in principle: extract every piece of inventory data you can reach, reconcile duplicate SKUs or mismatched item descriptions, then load the final result into a single .sql or .bak file that I can restore through SQL Server Management Studio. Please preserve every existing field that carries operational value—quantities on hand, reorder thresholds, location codes, cost figures, and any audit timestamps—and normalise the schema where it clearly improves reporting speed or data integrity. If a field appears under different names in different systems, map it consistently; if you uncover ga...

I have a fresh Manatal instance that needs to be structured correctly before we bulk-import roughly 300,000 candidate records. My immediate priorities are: • Field architecture – designing the custom and default fields so every profile, job, and placement record is future-proof and reports cleanly. • Matching logic – fine-tuning job title, sector, department, and location rules so relevant candidates surface instantly. • ATS workflows – mapping each recruitment stage, trigger, and status to match our real-world process while keeping it lean. Once you complete this foundation, another team member will handle the CSV import, so your configuration must be solid enough to absorb that volume without rework. I’ll provide admin access, our current proc...

I’m running a web application on a custom-built PHP framework and it currently sits on an ageing database that I now want fully migrated to MySQL. The job is strictly a database migration—no codebase refactor is required at this stage—so the focus is on cleanly lifting all existing data structures and records into a fresh MySQL schema while keeping the application functional throughout the transition. What I’ll hand over: the current schema dump (or direct access if you prefer), sample data, and a brief outline of the application’s data flow so you can map dependencies accurately. What I expect back: • A MySQL-ready schema that mirrors the original structure, optimised where obvious gains are available (indexes, data types, constraints). • Reli...

Our Magento 2 store suddenly refuses to complete the Product Price reindex and shows the familiar “no linked stock” message. Nothing was updated, no extensions were added, and I haven’t tried any quick-fix SQL scripts or CLI commands yet, so you’ll be starting with a clean slate. I’m looking for someone who has already wrestled with this specific indexing glitch and can get the catalog back to a fully reindexed state without disrupting live traffic. Acceptance criteria / deliverables: • Identify the root cause of the “product price index – no linked stock” error and document it briefly. • Apply the corrective fix (database clean-up, configuration adjustment, or code patch) on our staging site, demonstrate a successful bin/magent...
