    I’m an electrical engineer branching into artificial-intelligence projects and I need a reliable virtual assistant to keep the day-to-day work organised while I focus on model design. The role is entry-level, so if you have a solid grasp of basic AI concepts and genuine curiosity, that’s perfect—I’ll guide you through the technical pieces. Your help will centre on three areas: • Data entry – preparing training datasets, renaming files, updating experiment logs and keeping version-control notes tidy. • Research & documentation – gathering academic papers or blog posts on relevant architectures, summarising key findings, and turning rough notes into clear, structured docs. • Testing & troubleshooting – running scripted te...

    I need an external, black-box penetration test carried out against three separate /24 IPv4 ranges that power our public-facing web applications, email servers, and SIP services. The exercise must satisfy our compliance requirements, so the methodology, evidence gathering, and final reporting all have to stand up to an audit review. Here’s what I expect: • Reconnaissance, vulnerability discovery, and controlled exploitation performed strictly from an external perspective—no inside credentials will be provided. • Clear scoping and scheduling so the assessment covers every live host across the three networks without disrupting production traffic. • A written report that prioritises findings by risk, maps them to relevant compliance controls, and includes reprod...

    I’m pushing a software project toward the finish line, but recurring glitches in my development tools are slowing me down. I need ongoing technical support focused exclusively on software troubleshooting—everything from IDE freezes and mis-configured compilers to stubborn build scripts or version-control mishaps. You’ll step in whenever a tool breaks, share your screen if needed, trace the root cause quickly, apply the fix, and leave me with a short note that explains what happened so I can avoid repeat issues. Most of my work runs through VS Code, Git, Node.js, and Docker on a Windows/macOS mix, though I occasionally spin up Linux VMs. Experience reading logs, adjusting environment variables, and juggling plugin dependencies is essential.

    I have an app moving rapidly toward release and I want a fresh, methodical set of eyes to validate every screen, workflow, and edge-case before it reaches users. You will take full ownership of quality assurance—planning the test strategy, running focused cycles, and guiding me on anything that could compromise stability or user experience. The exact blend of techniques is up to you. If a deep manual sweep is the fastest way to uncover usability flaws, let’s do it. Should automated regression or performance stress-tests add real value, I’m happy to lean on tools such as Appium, Selenium, or JMeter. Whether the build targets iOS, Android, or both, your process should fit naturally into the current development rhythm. Deliverables • A concise test plan outlining scop...
