Skills Overview
Development & Operations
PHP
Using since 2010. I have a very strong understanding of OOP, MVC as well as language-specific concepts (namespacing, abstract classes, interfaces, traits, dependencies management, etc). In my career, I have been undertaking miscellaneous tasks such as application refactoring, performance optimization, designing internal mechanisms, 3rd party services integration, creating bespoke application mechanism without frameworks, developing RESTful APIs with Swagger documentation and many others, in all of which I have succeeded. I highly encourage TDD, as it has proven to me many times its benefits. I also developed my custom framework, as it really forces me to push my skills further.
JS/TS/React
Using since 2011. As a full stack developer I was originally developing using vanilla JS and jQuery. In 2015 I started to explore AngularJS and VueJS, which became my go to framework. However, in 2019, I started some React projects and I moved permanently to React, developing applications using either React App, NextJS or GatsbyJS. I also have strong understanding of Typescript, and experience designing and developing monorepos and custom packages.
CSS/SCSS
I am using CSS since 2009 and SASS since 2013. I have a very strong understanding of the CSS layout concepts. I write modular SASS code and I also worked with frameworks like Bootstrap, Susy and Tailwind. For React SPA I use styled components, MaterialUI or Tailwind and DaisyUi
MySQL
I use MySQL since 2010. I have an extensive experience writing complex queries including multiple joins, stored procedures but also designing databases, setting them up, configuring users with privileges, archiving, rebuilding, indexing and monitoring DBs.
Other
DevOps
Most of the applications I ever hosted were using AWS. I have set up basic infrastructure in my career many times, involving EC2, Route53, S3, CDN, RDS, Private and Public Subnets. For my personal projects I normally use Digital Ocean. I also have some experience using Google Cloud Platform.
I am also experienced with Docker (using since 2017). I wrote many custom images and each project I use is running on docker.
Other Languages exposure: Python, Ruby, Ruby on Rails
