I am a Computer Science Engineer, I worked 24 years in a large retail company in Chile, above allowed me to know various business areas and different design requirements for various systems in the group of companies. I trained in Database Administration, Database Systems Design and Database Applications Developer; the above I enable myself to detect and / or design the best solutions for clients, this in terms of obtaining the answer in the shortest possible time with the lowest cost in the use of hardware. The previous knowledge gives me the facility to detect if the problem is a) a poorly constructed SQL statement b) an inappropriate database design (lack of indexes, bad data statistics, unbalanced I / O load on tablespaces or disks, etc. or c) Contension with other recurring SQL, bad configuration of parameters in the definition of tables or indexes, etc.
I know that in www.freelancer.com I do not have the endorsement granted by the certifications and as a sample In good faith, I offer to optimize a single sql that you send me via chat for free, if my work satisfies you consider me for your project, if it is not satisfactory you are free to make the decision for who you judge to be the ideal candidate.
I am new to this platform so I need your good evaluation, because with it I can emerge on this platform.
My daily availability is 7 hours a day.
Sincerely
DRamirez
