You can understand it! Whether you're catching up in a coding bootcamp, or nailing a bug — reach me in the chat and we'll figure it out. I know you can, because I see it everyday! I enjoy explaining basics patiently, or move to advanced topics in my expertise anytime. Got a project idea? I can help you code it during a session or multiple sessions! If you feel overwhelmed about any of these — Javascript, CSS, React, Node, Firebase, web technologies in general — or actually just want someone to be around while you are figuring them out and point you in the right direction, just let me know. *BUILD & LEARN — one-on-one pair-coding learning experience with a mentor* Web development is my life, since 2002. For over decade I'm excited to work on the full stack of web sites and applications. With more focus on Front-end and Javascript full stack in recent years. **Practice Javascript** Javascript is probably the most versatile programming language that anyone can start even without installing any specialized software, as the developer tools are built into every browser nowadays. Your browser is a great playground to learn and understand Javascript, HTML and CSS, while also possibly making your experience with the web better. Install Node.js and enable the power of using the same language to access files on your computer and automate your workflow. Node comes with NPM - access to a repository of plethora of Javascript utilities for any task. **Practice HTML & CSS** CSS can be hard sometimes, but it's well defined with great tools to understand it built into the browser. Skills of building UI with HTML & CSS can now be reused not only for websites and web apps, but also mobile and desktop apps. And also your TV, your fridge and your nearby ATM. **Practice React** React provides building blocks to create components, where every component has UI defined with HTML & CSS, with Javascript logic attached to it. Scaling UI for a web app, mobile or desktop app becomes a no-brainer. Practice building on the web platform with me, I'll watch you 👀 and make your learning faster. **Let me hold your hand** (virtually) I know what it's like - to know how to do it, but still feel burnt out. Too easy to fall into an infinite loop of procrastination. Just schedule a session and let me be your focus buddy. I've seen work done in no time after a wait too long. ---- **How to call**: let me know in the chat what you need help or tutoring with. **Before the call**: message me, I may be available immediately, but most likely not—it's generally better to schedule a session, ask me for my availability (after telling me which technologies you need help with). **During the call**: In the codementor session room press "set up zoom", it will launch Zoom where you can share your screen. **If you messaged me and I didn't answer**: Don't be discouraged! There's a high chance I missed your message — feel free to message me again! Sorry, sorry, sorry! But do give a little bit of intro, so it's easier for me to answer whether I can help or not. ---- I only provide help during online sessions where you can share your screen and discuss the issues. ---- My focus: ● **HTML, CSS ● Javascript**, ES6 ● **⚛ React**, JSX, React-Router, Redux, Material-UI ● **Firebase for Web**: Database, Auth, Storage, Hosting, Functions ● jQuery, Backbone, Marionette ● AJAX, Axios, fetch ● async ● Git, Github ● npm, yarn ● Chrome DevTools ● **CSS Frameworks**, Bootstrap, Bulma, Foundation, Semantic-UI, SASS ● Handlebars ● **NodeJS**, ExpressJS, MongoDB ● Webpack, Browserify, Gulp, Bower, Require.js ● Jekyll ● Feel free to message me in the chat anytime — just tell me which topics you need help with — and we'll go from there. ---------------✁------------------------- If you are beginning your journey into web-development and need a longer session to go through the basics of technologies and tools listed below, then I am happy to offer my encouragement with about 20% off my usual rate. * Only applies to **longer sessions** of 1 hour and more. * Only applies to **practice sessions**, where you need help with fundamentals of the technologies listed below.
