Dream in code, like in the Matrix

I am an MBA who dive into the tech start up world with lots of programming skills on my belt. From brainstorming, draw up a strategy, to tackle a near-deadline specific-language just-this-one-problem until late at night (or in the morning -- that's why the coffee machine are for), or weekend sprint sessions, I'm your man. My goal is to help you bring your idea to life, your IT/coding problem gone, and overall make you enjoy more of your life.

TL;DR: I'm your man.

Worked professionally since 2003, 15+ years of professional experience from C, C++, Java, witness the birth of iOS, Android, web apps, the cloud, REST/API, the Blockchain, I've taste numerous services, platform, languages, tutored C-level executives to code, gave talks in colleges and corporate settings.

Code since 15 years old, teach my self BASIC and then Visual Basic, HTML. Sold my first app (Attendance with SQL database) and first certification, MCP at 19. Studied Computer Science and Business, worked in IT Consulting and large manufacturing group as their Business Analyst for seven years, and another nine years in the start up scene, mostly in agile mobile application development, back end systems, testing, and project management.
