ABOUT ME
Javascript Architect, UI/UX fan, & Performance and Clean Code Advocate
Javascript Architect, UI/UX fan, & Performance and Clean Code Advocate
Hi there! I'm Sergei Garcia, and I’m a Sr. Software Engineer (+fan of UI/UX design) with +7 years experience building high performance, clean, maintainable code for web apps. I'm currently working with Deviget as a JavaScript Architect building an awesome Vue/Next/GraphQL application, and also have over 2 years experience in education/mentorship thanks to having participated in various coding bootcamps. Also as part of my qualifications, I'm a certified Mobile Web Specialist by Google which includes qualifications in PWA's, and mobile/network performance optimization.
I'm just a guy who loves code immensely, and doesn't shy away from a chance to share the love for it. Either by mentoring 1:1 those in need, or hosting presentations occasionally. I take immense pride in all of my work's quality, and in always leaving every project I work on in a better state than I found it.

By far, my strongest skillset. I simply love JavaScript. And have done nothing more the past couple of years honing this skill. I find what many people find intolerable, quirky features of the language quite simply, fascinating. From closures, hoisting, prototypes, this/scope binding, design patterns, functional programming, classes, transpilers, you name it. I love it all, but above all else, I love expressing the love for it by explaining complicated JavaScript concepts in a simple fashion.

I have worked across a large variety of React apps over the years, from simple Front Ends using vanilla React, to Server Side Rendered React apps, to full blown scalable apps using things like Redux/Apollo GraphQL/React Native.
I have a particularly strong interest in building React apps the clean, mantainable, performant way. Be it by writing clean JSX, not relying on external libraries unless it's absolutely possible, avoiding non-performant patterns for react apps, etc.

As a fan of good UI/UX design, one of my core principles while building web applications is maintaining strong performance. Be it by making sure assets are loaded in the most efficient manner, adding critical path rendering, or finding JavaScript performance bottlenecks causing sites to run sluggish. Because what good is a site that looks pretty, but is frustrating to use? Also worth mentioning, is I'm a certified Mobile Web Specialist by Google, which includes mainly mobile and performance oriented qualifications.

I have quite a lot of experience in Node despite starting primarily as a front end developer. Building a back end in JavaScript, even when compared to full blown static languages like Java and C# just feels right, more agile.
I have built servers using nothing more than the native http module, to using libraries like Express and Hapi.js. Also, I have done a fair share of database work using NoSQL and SQL libraries such as MongoDB and Postgres. And more recently, I have done quite a a lot of GraphQL work, and even built an entire GraphQL back end and front end integration from scratch recently which implemented Redis caching.

Despite not having as much experience in Vue.js compared to my other frameworks, I managed to learn it rapidly thanks to my background in libraries like React and Angular.js on which Vue is strongly inspired from. I have worked on projects ranging from only Vue, to full blown Vue apps using the Server Side Rendered Nuxt stack, with Apollo GraphQL and Vuex for state management.

I have done large amounts of testing over the years. This includes the entire testing piramid rangin to Unit Tests, Integration Tests, and UI/Automation tests. Starting from older libraries like Jasmine.js, to more modern and extensible ones like Mocha and Jest. I have also tested a large amount of front tools included but not limited to: Angular 1 (Protactor), Backbone (Mocha), React (Enzyme), Node.js (Jest).
Also, I have done quite a fair amount of automation testing via Selenium using Webdriver.io and more recently, have moved to using Puppeteer from the official Chrome Team as it has proven far more powerful than even Selenium. All in all, I find testing quite enjoyable!

I am no stranger to mentorship, as I have participated as a private, and full time mentor at various places througout my career. Ranging from local, in-person classroom environment bootcamps, to private 1:1 mentorship through large established educational institutions like Thinkful, to career counseling.
I believe what makes me such a great mentor, other than my positive energetic attitude and patience, is possibly how much I am in love doing what I do. Which in turn translates to me always wanting to get other people to fall in love with coding as much as I do.
