In this talk we will take a pragmatic journey through using the OCaml programming language to deliver real world systems. Along the way we will look at elements of engineering design, talk about tradeoffs between various solutions, discuss where to spend your innovation budget, and address the non-technical side of a project that often dictate whether a project succeeds or not. The talk will take the form of an experience report distilled from my experience designing, implementing, and delivering real world projects written in the OCaml programming language. I hope to share with you the learnings from my experience, introduce the general purpose programming language OCaml, and convince you to try out OCaml.
