    I need a reliable professional who can keep a constant watch over my existing CCTV network and alert me the moment anything suspicious appears. Your core focus will be real-time monitoring; I already have the cameras in place and simply need vigilant eyes and quick communication when an incident occurs. You will connect to the system remotely, observe the live feeds during agreed-upon shifts, and send rapid summaries—text or voice—whenever you spot movement or behaviour that looks out of place. I’m not asking for deep-dive footage analysis or hardware maintenance right now, but familiarity with those areas is a bonus in case our needs evolve. Please be comfortable with standard CCTV viewing software, stable internet connections, and concise incident reporting. If yo...

    I run a corporate website and need a reliable IT pro to guard it around the clock and keep our pages visible in Google. At the moment no formal security stack is in place, so the first priority is to harden the site—firewall, malware scanning, secure backups, the works—then keep intruders out through continuous monitoring. Equally important is making sure every page is indexed and healthy in Search. You’ll watch Google Search Console, fix crawl or coverage issues, and adjust on-page SEO so new content is picked up quickly. Key deliverables • Deploy and configure security measures from day one (SSL best-practice, web-application firewall, automated backups, vulnerability scans). • Set up 24/7 monitoring with instant alerts for intrusion attempts or down...

    I’m launching a brand-new blog and need a developer who can turn the idea into a polished, responsive website. The project centres on website development—think clean code, fast load times, and a layout that makes articles easy to read on any device. I’m flexible on stack: WordPress with a custom theme is fine, but I’m equally open to a lightweight framework if you can demonstrate why it’s the better choice for performance and security. Alongside the build, I also require translation support so the site can reach audiences in more than one language. If you’re comfortable structuring a multilingual setup (for example, using WPML, Polylang, or a comparable solution), please let me know how you’d integrate it and keep the workflow simple for new posts...

    I need a seasoned security specialist to dive into our online card-and-board-game platform and expose any path an ordinary player might use to escalate privileges through the interface. That is the single most critical outcome of this engagement. While you work, I also want you to examine the WebSocket layer—specifically its data-encryption implementation—to be sure that every message travelling between client and server stays confidential and tamper-proof. You’ll be looking at live traffic the same way a determined attacker would, so expect to spend time in Wireshark or a similar PCAP tool as you capture sessions, replay them, and probe for weaknesses. If deeper packet analysis or anomaly hunting becomes necessary, I’m open to extending the scope, but the first mi...
