(I have dozens of example documents in 4 PDFs.) I can write responses to RFP's (Request for Proposal) that help you win projects big and small.

I was invited by the Reagan administration to represent the United States in a contingency of Computer Scientists in a US/China technical exchange under the People-to-People program. I can address any problem of Mathematics/Logic/Computer Science e.g. redesign a database or set of websites to support multiple company locations or optimize a Stochastic Process. menos
