    My main objective is to share. Being an Open Source developer, I like to share my experience with and for my clients. I build code, like to refactor and bring efficiency to the table. I also strongly believe in Cloud Computing when all powerful engines can be shared not only to save cost but to save energy and consumption. The lesser code I write, the happier my clients are. Functional Programming fits that bill because code is just concise. My goal is always to find the most efficient tool that can save time but not impact performance. I choose to focus on Functional Programming like Haskell, Scala, Clojure, ELM, Rust and Terraform. I still code with Imperative Programming like C, Assembly, Rust for FFI (Foreign Function Interface) Integration. I deploy all my apps following the Reactive Programming Concepts and deploy on MicroServices platforms using Docker, Kubernetes on Metal and Cloud. My hobbies go towards game development and audio/video streaming on the iPhone, Android
