Based upon what you assert, you do not meet the definition under the FLSA for an exempt computer professional. I have handled many similar cases. IT support, tech support, typically is not an exempt position and non-exempt duties. Definitely consult a lawyer. You could consult nationalovertimelawyer.com for more information.
The hiring of a lawyer is an important decision and one you should not make just upon reading something. While I may generally provide some helpful information and an answer to your question, this is not meant to be direct legal advice to you. If you wish legal advice, many attorneys offer free consultations on certain legal issues. If you wish to be certain about how best to proceed to protect your legal interests then I encourage you to contact the lawyer with experience in the same area of law
I sounds like you may not be exempt from overtime pay. You should meet with an employment lawyer who handles overtime claims to fully evaluate your potential claim and help you decide what action (if any) you should take.
