"As within so without..."

I've been working as a senior Database Administrator (DBA) for over 15 years; I possess extensive knowledge and experience in managing critical database servers running on Microsoft SQL Server platforms. I provide my customers with the Best 24x7 Remote SQL DBA Services — a cost-effective way designed to serve your needs of database management. I'm looking forward to making your databases run significantly faster.
Besides my passion for database query processing and distributed database systems, I am also a computer scientist working on cryptography —  cryptographic Boolean functions, algorithmic cryptanalysis, number theory, and other algebraic aspects of cryptography — I am focused on the mathematical side of cryptography. I did a Master in Advanced Computer Science at Loughborough University, England in 2018, where I am currently doing a PhD in Computer Science (Cryptography). 

I've been writing about SQL Server administration issues on my blog since 2005 — nowadays I only write for MSSQLTips.com; you can access all my published articles here. In this blog, I mostly share my thoughts and knowledge on cryptography.
