Project details
You will get is an original and well thought out IT Security consultation, that will fully leverage my skills and experience while being tailored around your particular requirements. It will be delivered in a professionally written document (in both doc and pdf format).
I am an IT Security specialist with 15+ years of hands on design and development experience in real world systems (both Linux and Windows platforms) as well as in PoCs created as part of Cybersecurity related academic research projects. The breadth and depth of skills and expertise I possess is very significant and can help me discover not just the specific issues with a particular solution or technology but also have a better grasp of the big picture and the long term effects of certain architectural and solution deployment choices. I have good experience with all three major cloud service providers: GCP, AWS and Azure and I have developed and deployed real world solutions on all of them, some even involving HSM services (AWS)
Please also note that I am recommended by the head of Privacy Engineering @ Android on my LinkedIn page (check my Upwork profile here to find it).

MS Word & Excel Add-in development
We have worked with Alex several times over the past few years. He is a true professional developer with good communication skills and always goes the extra mile to make sure the project is successful. He has a thorough understanding of Microsoft 365 inner workings and helped us develop a Microsoft 365 add-in with Intune & SSO security. Will definitely hire Alex again for future projects.

** My 4.2 stars rating is only due to a 9-years old 100K project that was successful but the client only rated it 4.0, due to his particular style of being strict with ratings. This rating only took effect recently due to Upwork making the choice to include LIFETIME ratings. Without it, my overall stars rating would be 4.9**

Steps for completing your project
After purchasing the project, send requirements so Fotios can start the project.
Delivery time starts when Fotios receives requirements from you.
Fotios works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements refinement
I interact with the client in several ways until the requirements are well fleshed out and with enough technical insight added to them.
Security Assessment & Penetration Testing
I will review the architecture, software components, and source code of your solution, and in the case of web apps or servers being security assessed, I will also perform penetration testing using several tools. I will interact with you as needed.
