I'm a Penetration Tester and Cyber Security Specialist who is a professional in evaluating the security posture of Web-Applications (Websites) and ensuring the security of personal clients' online identities, accounts, devices, and networks, I've possessed my current knowledge through 3+ years of self-study and research plus 2+ years of work in the industry, protecting clients on a personal level and running vulnerability assessments against business websites, always leaving positive impression and impact, I hold a great record of being able to expertly provide the following services: - Perform comprehensive security checkups on Emails and Phone numbers and pinpoint security holes which often lead victims to be hacked with zero interaction nor awareness from them. - Assist in Account Recovery (Ex. Instagram, Facebook) - Educate thoroughly on the findings and remediations for a vulnerable target, equipping clients with enough information to trust themselves as they continue to utilize the technologies as normal with no fear of being targetted by hackers. - Investigate and educate on online frauds/scams, especially crypto ones, why and how they work, and how to distinguish between legit and not legit easily. - Clean up networks and devices from viruses/malware and ensure optimal patching for security. - Report fraud websites that impersonate legit businesses for a takedown. IMPORTANT: When it comes to cybersecurity-related services, there is a number of scammers not to be underestimated, whether within or outside of Upwork, therefore stay vigilant and keep in mind the following, 1. If you were scammed online via crypto, there's no one out there with the right to give a guarantee that they will be able to recover it for you despite how well furnished the so-called hacker's portfolio appears to be, the chance remains very slim and you should only pursue this kind of service for the sake of leaving no stone unturned knowing the high probability of failure, and you should only select a freelancer with a reputable profile and reviews to back up their activity because scammer accounts are usually fresh with no reviews and no verified ID, feel free to consult me to evaluate that. 2. Same applies to the request of hacking an account, there are complicated caveats that explain why it DOES NOT work the way you think it does but to keep it short, if you want someone's account hacked, aside from it being illegal and unethical and isn't the type of "service" I provide, the chance for it to work is about 1% to begin with, again, I'm available for consultation, account recovery is a different subject with a higher probability for success as long as it's your own account that was lost/hacked.

I protect your content from getting stolen over the web and if someone is using your content without your permission, I report and take down the pirated content under DMCA. I provide services to online content creators such as writers, bloggers, photographers, and the companies who own intellectual content of any type, or copyright products. My motto is to end content piracy. Here is my Plan of action: 1) I start by searching for all the websites which are stealing and using your content, through all the web search engines (Google, Bing, Yahoo, AOL, Yandex, etc.) using multiple effective keywords. 2) I de-index (remove) those websites from the search engines. It will help to stop your audience go on the infringing website in the first place and this process also helps if the infringing website is not willing to remove the content directly. 3) Send DMCA takedown notices to the website owners and their hosting providers. 4) Reporting infringing content on social media platforms and video sharing websites like Facebook, Instagram, Pinterest, Reddit, YouTube, Twitter, Dailymotion, VK, OK, Youku, Archive.org, 4shared, Vimeo, Google-drive, and many more. 5) Keeping a complete follow-up of the work done. 6) Provide you with weekly reports regarding the work and progress. Why choose me? I leave no stones unturned in protecting your content. Moreover, I am committed to providing customer satisfaction. I make sure that my client is up to date about the work progress and is able to get a complete follow-up regularly. I put all my efforts in a task that I have assigned. Let me assist you with my quality service. Thank you.
