The feature set is broad—registration/login, product browsing, cart, order management, push notifications, profiles—but your first mission is crystal-clear: safeguard the entire checkout and payment integrations flow. You’ll own the full setup: selecting the most effective mobile-friendly framework (Selenium, Appium, TestComplete or another you can justify), configuring device coverage, writing maintainable scripts, and wiring everything into our CI pipeline so tests run on every build. Clear, actionable reporting is essential; I want to see failures pinpointed down to the step. Deliverables • Automated test suite focused ...

We have a WordPress plugin that sells services on a CREDIT model. It is already CODED and already TESTED on a local machine: 31 of 33 smoke tests pass (the remaining 2 wait on OUR input data, not on defects) plus 6 of 6 payment-gate tests — including a real PayPal SANDBOX payment and refund. We need an experienced developer to take it onto a real staging domain and turn it into an accepted, live system: Stand up a fresh WordPress -> install & configure the plugin per the docs -> RE-RUN the provided acceptance suite on the real domain (30 smoke tests in M1; the 3 dataset tests complete the 33 in M2; plus 6 PayPal-gate tests) -> fix anything the real environment exposes -> go live on PayPal (one real transaction + refund) -> finish the operator docs ->...
Please guide me through the entire workflow of capturing and interpreting Windows Performance Recorder (WPR) traces with an emphasis on CPU-usage investigation. We will use Windows Performance Recorder and Windows Performance Analyzer, starting from creating the right capture profile, through loading the ETL file, to drilling into CPU Sample stacks, hotspots, and thread activity. Along the way I want clear explanations of what each graph means, how to filter noise, and how to translate the results into actionable optimization steps. To make sure the learning sticks, I’d like: • A live screen-share or recorded walkthrough (your choice) covering at least one real trace • A concise, step-by-step cheat-sheet I can reference later • A short sample report showing how...
My five-person consulting firm needs a dependable partner who can handle our day-to-day IT environment entirely off-site. While we will continue to lean on you for onboarding and security matters, the area that will make or break this relationship is ongoing IT support; keeping us up and running without hiccups is the priority. Here is what the engagement looks like from my side: • On an average month you will perform regular system maintenance, jump in quickly to troubleshoot anything that crops up, tune performance so laptops stay snappy, and spin up new machines or cloud user profiles whenever we add a team member. • Remote desktop tools, monitoring and management software, and solid security software should already be in your toolkit so you can diagnose issues, patch syst...

I need an English-speaking voice AI that can step in as a quality-assurance assistant during live or recorded calls. Its two core duties are: • Verifying the accuracy of caller data and any details captured in our CRM. • Conversing naturally with customers about general inquiries to keep interactions smooth while it checks that information is logged correctly. The agent should detect discrepancies on the fly, request clarification when something doesn’t match our records, and flag any mismatched fields for review. Real-time transcription, intent recognition, and a brief post-call summary of corrections will help my team close the loop quickly.

I need a focused penetration test against one of my applications. The engagement is limited strictly to the application layer—no network or infrastructure testing—so I expect you to probe for the kinds of issues highlighted in the OWASP Top 10 and similar standards. Here’s how I picture the engagement: • Pre-engagement call to confirm scope, test window, and rules of engagement • Hands-on testing that blends automated scans (Burp Suite, OWASP ZAP, or your preferred tools) with manual verification and exploitation where safe • A concise yet comprehensive report that includes an executive summary, risk ratings (CVSS v3 or equivalent), step-by-step reproduction, screenshots or PoC scripts, and clear remediation guidance • An optional debrief sessi...

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. Software testing is just as important. Please validate operating-system ...
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. If you’re comfortable troubleshooting legacy PHP and tightening up HTML markup when it causes functional glitches, I&rsquo...

I’m experiencing persistent issues in my web application that need to be tracked down and eliminated. Pages occasionally break, certain features behave unpredictably, and error messages are starting to appear in the browser console as well as the server logs. The exact layer—frontend, backend, or database—hasn’t been pinpointed yet, so I need a developer who can methodically debug across the full stack, isolate root causes, and deliver clean, tested fixes. Scope of work • Reproduce the reported errors and identify their source in the codebase. • Implement corrective changes without introducing new regressions. • Document each fix clearly so future maintenance is straightforward. • Provide a brief hand-over summary outlining what was wrong,...
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...
