CHARACTER
From a very young age I was awarded numerous accolades and was considered by many teachers to be a child
prodigy, specifically in the areas of Math, Science and IT. I have always had a passion for advanced technologies.
I have owned nearly every type of personal computer since around 1987, when I was 10 years old. My first
computer was an Apple II, followed by a Commodore 64, Atari computer and others. By age 11, I had a very advanced
level of programming skill using MS-DOS and the BASIC language. In high school, I learned the C and Pascal
programming languages as well. I won numerous knowledge bowl, spelling bee, science competitions and programming
contests – I won several tournaments against high school seniors (3 years older) while I was still in 9th
grade.
While still in Junior high school (1990-1992) I taught adult education computer courses at FIU and substituted for
the computer teacher of Palmetto Junior High School nearly every week. Because of my academic achievements, I was
selected to attend college two years early in the School for Advanced Studies Honors College Dual-Enrollment
scholarship program at MDC. I was 16 years old when I went to college. My educational focus has always been IT.
The majority of my IT education was primarily self-taught from books and hands-on lab work. I consider myself
primarily an autodidact, although I also have the benefit of many years of academic instruction as well. I now presently
maintain and update my IT knowledge using a wide variety of online courseware and interactive materials to keep my
skills sharp and at the cutting edge. I frequently Beta test new versions of software when they first become available.
During my career in network systems administration, engineering and consulting, I have earned the respect of my
peers, employers, clients and co-workers for being a highly efficient problem solver and troubleshooter. Also, I have
enjoyed the opportunity of managing many successful, yet challenging, enterprise-class projects.
I’m very observant, with a keen attention to detail and the ability to learn very quickly and intuitively. I enjoy
managing, helping, educating, mentoring and working with others. I am a very positive, optimistic, energetic and
enthusiastic person. Some additional qualities that I use to describe myself are that I am highly confident, motivated,
entrepreneurial, honest, sincere, and dedicated. If I don’t know the answer to a question off the top of my head, I know
that I can always find the answer very quickly. I have always been expected to be able to work with and learn the latest
new systems and software.
My goal is always to enhance the efficiency and profitability of my employer and clients by providing a stable,
reliable and optimal enterprise-class Information Technology infrastructure.

  • 7. EDUCATION Miami-Dade College Major: Associate of Science - Microsoft Network Engineer/ MCSE Windows 2003 Completed only Core Academic & Technical Courses Miami Dade Community College Completed Microsoft Networking / MCSE Windows NT curriculum 1998 ITT Technical Institute Electronics Engineering Technology Completed One Full Year of this Program School for Advanced Studies Honors College Dual-Enrollment at Miami Dade College High School Diploma, Graduated 1995 Full Honors Scholarship CHARACTER From a very young age I was awarded numerous accolades and was considered by many teachers to be a child prodigy, specifically in the areas of Math, Science and IT. I have always had a passion for advanced technologies. I have owned nearly every type of personal computer since around 1987, when I was 10 years old. My first computer was an Apple II, followed by a Commodore 64, Atari computer and others. By age 11, I had a very advanced level of programming skill using MS-DOS and the BASIC language. In high school, I learned the C and Pascal programming languages as well. I won numerous knowledge bowl, spelling bee, science competitions and programming contests – I won several tournaments against high school seniors (3 years older) while I was still in 9th grade. While still in Junior high school (1990-1992) I taught adult education computer courses at FIU and substituted for the computer teacher of Palmetto Junior High School nearly every week. Because of my academic achievements, I was selected to attend college two years early in the School for Advanced Studies Honors College Dual-Enrollment scholarship program at MDC. I was 16 years old when I went to college. My educational focus has always been IT. The majority of my IT education was primarily self-taught from books and hands-on lab work. I consider myself primarily an autodidact, although I also have the benefit of many years of academic instruction as well. I now presently maintain and update my IT knowledge using a wide variety of online courseware and interactive materials to keep my skills sharp and at the cutting edge. I frequently Beta test new versions of software when they first become available. During my career in network systems administration, engineering and consulting, I have earned the respect of my peers, employers, clients and co-workers for being a highly efficient problem solver and troubleshooter. Also, I have enjoyed the opportunity of managing many successful, yet challenging, enterprise-class projects. I’m very observant, with a keen attention to detail and the ability to learn very quickly and intuitively. I enjoy managing, helping, educating, mentoring and working with others. I am a very positive, optimistic, energetic and enthusiastic person. Some additional qualities that I use to describe myself are that I am highly confident, motivated, entrepreneurial, honest, sincere, and dedicated. If I don’t know the answer to a question off the top of my head, I know that I can always find the answer very quickly. I have always been expected to be able to work with and learn the latest new systems and software. My goal is always to enhance the efficiency and profitability of my employer and clients by providing a stable, reliable and optimal enterprise-class Information Technology infrastructure.
