    I need a focused penetration test against one of my applications.

    My recently serviced laptop is back in my hands, but before I sign off on the repair I want independent confirmation that everything now performs exactly as it should. I need a technician who can put the machine through its paces, documenting every step so I have clear evidence of its condition. The scope covers both hardware and software. On the hardware side I want the CPU and RAM stress-tested, the hard-drive and SSD examined for bad sectors and health metrics, and the battery/power supply checked for proper charge, discharge and wattage behaviour. Standard tools such as MemTest86, Prime95, CrystalDiskInfo or similar are welcome—use whatever you are most comfortable with as long as results are reproducible.

    My existing site is built with plain PHP and standard HTML templates, and a few lingering bugs are holding it back from running smoothly. I need an experienced developer to dive into the current codebase, track down the issues, and deliver clean, well-commented fixes that don’t break any of the working pages. You will be working only on functionality—no design or content changes—so your focus is on debugging, refactoring where necessary, and ensuring page loads and actions perform reliably afterward. Once the patches are in place I’ll test them on staging, and we’ll wrap up with a brief hand-over explaining what was changed and why.

    I’m in the closing stretch of a .NET Core microservice project and need an extra set of experienced hands to get us over the line. The architecture is already in place and running in containers, but several new endpoints and service refinements still have to be coded, tested, and deployed. Your focus will be pure development inside the existing Dot net Core microservices: writing clean C# for REST endpoints and message-bus consumers, extending EF Core queries, and ensuring every change sails through our Git- and Jenkins-based CI/CD pipeline. Once the code is committed you’ll containerise it, update the Helm charts, trigger the build, and keep an eye on Kibana to confirm the logs are healthy. Gatling drives our load tests, so any change must survive that suite before we call it...

    I want to start doing basic desktop publishing in Bengali on my Windows PC, but I’m a complete beginner. Your first task is to pick a Windows-friendly publishing program that makes text formatting and simple graphic editing painless. Send me the direct download link (or the installer itself) and guide me through installing and activating it—screenshots, a short call, or any clear walkthrough is fine as long as I can follow along easily. Once the software is running, load my system with a full set of Bangla Unicode fonts. Kalpurush is essential, but I’d like several more common faces so I can switch styles freely inside the new program and in other apps. Make sure the fonts register system-wide and show up automatically in the publishing software. Deliverables: • Re...
