• Introduced and implemented multiple architectural solutions (mostly on front-end)
• Improved page loading speed (decreased front-end bundles size by 2 times)

It was an exciting project for a startup company in the health and wellness area. I've started on the back-end only and after a few months, front-end was added too. I have been working with existing development team around 10-15 hours per week.

• Developed back-office for API from the scratch as SPA on Vue.js (axios, vuetify)

Develop, maintain and support application using PHP, Wordpress, Nodes and related tools; take care of git repo (review, merge and deploy the code); configure environments for the apps (Linux, Nginx, Apache); manage a team of three programmers (without me); train and consult programmers

• Measured and improved page loading time of the different sites by Nginx/Apache configuration, DB and server-side caching (from 6s-10s to 0.5s-2s)
• Improved security of the few products by configuring OS, server and the code (CORS, XSS, CSP, etc)
• Developed and maintained real-time chat module for the product on Node.js (Express + socket.io + Mongo + PM2)
• Prepared few production/staging servers, set-up git auto-deploy
• Trained and mentored junior programmers in programming methodologies and best practices (especially JavaScript/PHP). I held seminars about JavaScript/PHP/Node.js, security, and performance.

Underwent "C# Core" course from "WinInteractive",

Play Volleyball,

etc
