Sergiu Mare - front end developer

Welcome to my page, my name is Sergiu Mare and I am a Front-End | Javascript Developer.

I have been working in the web development industry for more than 5 years.

I am a web developer specialized in the front-end.

I specialized in working on large-scale projects with front-end frameworks like Vue.js and React.js.

I feel comfortable working alone on a web solution or to be part of a team of developers.

These are some of the words which I like to hear when starting a new project: coding standards, testing, documentation, scrum agile, ci/cd, version control, design, API, component-based framework, and cms.

About me and my technical side



What I like about javascript is that I can use it server-side and client-side. I can write scripts that run in the console and in the command line. I like the fact that I can write object-oriented code and also functional code.



I like to use Node.js and Express.js to develop the back-end for applications. I have used it in the past in the projects in which I have been involved in. I like the flexibility which Node.js offers through Javascript.



An awesome component-based framework. I have used it in the past and is my first choice when building a project. I love how Vuex integrates with the framework, and how easy is to read the code. Also, the documentation for Vue is awesome.



A mature library, for developing enterprise web applications. I like the fact that typescript integrates well with it, there are options in regards to which state library to use and the vast community around it which can provide solutions for various problems.


Testing sofware

I love testing. I like to write unit tests, integration tests, and end-to-end tests. Testing makes everything more secure and nowadays is crucial to deploy features fast and secure, and the only skill which can support this is testing.
