    John Comeau

    expert troubleshooter, generalist developer, tenacious problem solver

    United States - Last active: 8 days ago - Tests: 2 - Portfolio: 1

    "Jack of all trades, master of none" is typically said in a derogatory fashion, but I adopt the title gladly, and you will not likely find more than a few dozen generalists worldwide who can match my troubleshooting and problem-solving skills. I've been programming, on and off, for 40 years, if you count my study of BASIC in 1968, 6 years before I actually got my hands on a computer: the DECSystem-10 at Worcester Polytechnic Institute. As a result of working on computers and microcontrollers of various sizes and capabilities over the years, I have learned to get to the basics of a problem, come up with a prototype solution, and refine it to the customer's satisfaction. My methodology, which I found later is used by many successful programmers, is "build one to throw away"... once the code is working, rewrite it from scratch, correcting the false assumptions made in the first attempt, and refactoring to make a clean, maintainable, codebase. My background in both the electrical/electronics side of things plus years of experience reverse-engineering and improving software on dozens of different architectures gives me the rounded background necessary to take on projects which leave specialists lost. I may charge more than most ($100 is my usual rate, but I found it's unrealistic on Odesk), but when you've run up against a brick wall, I can likely find a way over, around, or through it.
