A & N Family Professional Business Services is the home for all things tech — web development, Linux server administration, backend systems, and technical consulting. Founded by Nicole M. Taylor, a developer with 35+ years of computing experience and a BS in Computer Information Systems, bringing real-world expertise to every project.
I'm a United States Marine Corps veteran and National Defense Service Medal (NDSM) recipient — and I bring that same discipline and commitment to everything I build. Based in Fort Worth, Texas, I've been deep in computing since 1989, starting with BBS culture, FidoNet, and ANSI art long before the modern web existed.
I hold a Bachelor of Science in Computer Information Systems from the University of Texas at Arlington, built on an Associate of Arts in Business Administration — where I graduated with honors in 2023 from Tarrant County College. A CPA certification is a future goal through continuing education.
On the tech side I specialize in full-stack web development, Linux server administration, MySQL database design, and backend systems — with real deployed projects and published tutorials to back it up. I also run three businesses and am launching a fourth: A & N Family Professional Business Services.
When I'm not writing code, I'm writing tutorials that skip nothing — step-by-step guides built from real experience on real hardware.
Everything I work with regularly — from production servers to development tools to the vintage hardware still running in my lab.
Live websites, production applications, and school projects — all built and managed by me.
My primary tech brand — offering web development, Linux server setup and administration, backend systems, cybersecurity consulting, and technical support for businesses and individuals in the Fort Worth / DFW area and remotely.
