With over 25 years in the software industry, I bring a robust mix of hands-on engineering and management expertise. Currently, I lead the teams for Gemini Code Assist at Google, where we develop and scale backend systems and extensions for both VSCode and IntelliJ to deliver high-performance code assistance. As a startup founder and an innovator, I enjoy wearing multiple hats, diving into new technologies, and taking prototypes from rapid development to production-scale systems. Proficient in over 15 programming languages, I primarily focus on JavaScript, TypeScript, Node.js, Electron, and Web technologies, with occasional use of Python. My approach is rooted in scalable solutions and inspiring teams to deliver impactful results.

Freelance Ext JS Developer - Uzair Faisal
Freelance Ext JS Developer5.0 (45 reviews)

I'm a **polyglot fullstack software developer** (*I'm able to effectively work with multiple languages, tools, and frameworks*) with over 13+ years of industry experience in web application development. I'm also an instructor and mentor in various bootcamps having lead class cohorts, mentored groups of students and 1:1 tutoring sessions. I'm experienced in **Python**, **ECMAScript** (Javascript or Node.js), **Java**, **C#** **Ruby**, **PHP**, and even **Scala**. I work in both frontend and backend spectrums of the web stack, so whether you're debugging something in React.js or you're stuck on a complex SQL query, I'm more than happy to help in your code debugging adventures. My instruction style is that I like to guide the student towards learning *how* to solve rather than simply giving you the solution - I don't believe a student should be stuck on always referring back to a senior developer to get unblocked, but should be empowered to solve their own problems. Now that's real mentorship!

I have 12 years experience working in software development. My strength is in front end development and user experience, however I am considered a generalist because I have been a full stack developer as well as worked in databases using SQL.
