I have developed a wide range of software solutions for ... morea diverse set of employers and clients, including Google, Reputation.com, NASA, US Air Force, US Navy, South Florida Water Management District. From web search to data mining, web sites to truck scales, and hypoxic pilots to Martian rovers, my software solutions have helped people solve their problems. My core skills are in software architecture: design the system right and the implementation flows like water. I am looking for tough problems that require novel solutions. I have experience in C/C++, Ruby, Perl, PHP, Rails, MapReduce, and SQL and non-SQL databases, a strong mathematics background, and a Ph.D. in Computer Science. When you select a provider, keep in mind that hourly rate is only one variable in the total cost calculation. I provide quick turn arounds with stable products. While my hourly rate is high, my total cost to you is not. Nor do I rely on code generation tools available to the masses. You will receive custom software tailored to you situation. less
