So, you want to create a fancy website or web application. You *"embellished"* your resumé by saying you are a competent web developer, and now you've landed the job and don't know where to start. You keep hearing about cross-platform mobile apps, where writing a single piece of code gives you an Android AND an IOS app, but don't know much beyond that. You know the basics of HTML/CSS/JS but everyone keeps bugging you about React this, Fullstack that, and you have no idea what that is, and would like to change that. Or... you’re starting from zero and you simply wish to learn. If you fit in any of those categories (and others), I'm your man. If you’re feeling overwhelmed by the overabundance of tools, frameworks and fancy terms, don’t fret, **we’ve all been there**. And I’m here to make the process painless. We can take things one step at a time, no matter your level. Or maybe you just want help looking over your code, smoothing out bugs, or someone to accompany you while you bring your next idea to life. Not to worry; I can help. I have over **8 years** of experience as a Fullstack NodeJS developer, with a special focus on React and React-native, which is basically just fancy lingo for saying I make websites, apps and mobile apps very fast. I can accompany you on your journey from absolute beginner to expert level, if you'll give me a chance.
