ABOUT ME

President at FlechaMobile Inc

Hi, I'm Steven and I'm a Digital Nomad programming and travelling the world for 8+ years. I speak Dutch (native language), English and Spanish.

I started programming and hacking when I was around 12 - 13 years old using SoftIce (Assembly) and moved over to web programming over the years and I now specialize in web apps written mostly in PHP and Javascript.

My biggest programming accomplishment is creating a split-test engine to the likes of VWO / Optimizely. An advanced Javascript (with PHP back-end but could easily be replaced with other back-end language) engine that I've been developing for 3 years now which is being used in a few SaaS applications of my own making and managing.

I'm looking forward to make new connections using CodeMentor and helping you solve your coding problems!

My biggest reason for being here on Codementor is helping programmers go 'programpreneurial', I want to help programmers start thinking as entrepreneurs and maybe start setting up their own businesses (either productized services or products).

Project Management, people management, maintaining scope, planning and meeting deadlines. As a programmer many of the aspects involved with PM are difficult concepts but through many failures and few successes I'm getting better and more experienced in the field. I especially understand the difficulties programmers have with the non-definitive state of a plan and the fact they are fluid and thus change over time. Matching this with the expectations from programmers can be hard.

I've written a complete A/B testing engine of which most of the core is JS and re-purposed the functionality to several of our products. The core of this engine is on par with products like VWO and from reverse-engineering theirs it is actually faster in loading the changes as well.

Been doing front-end development since I was 14. I mostly work with Bootstrap. Must admit I should look into SASS more but when required I'd be able to pick it up within a few days. Did you know that most sites carry an enormous amount of not-used CSS selectors making them slower then they should be?

I try to avoid using JS frameworks as much as possible. People tend to forget that native JS is always faster. If you can do something in 5 lines of native JS compared to 1 line in Jquery (or other framework) in many situations I'd choose for the native implementation. Though frameworks like jQuery obviously do have their uses and if it must be included you might as well use it with all its potential.

The data model of any (SaaS) application stands or crumbles the end results. It doesn't matter how good of a programmer you are if the data model is bad your application will always be crippled. I've learned all the normalization levels (up to BCNF) although most of the time the 3rd level is enough. Mysql is more powerful then most people know and relations are often under-utilized (especially the Cascade options). The 'EXPLAIN' feature is also very much underused.
