WordPress Developer at Negotiation Experts
2023 — 2024
Skills
I maintained and added new functionality for a course website/store jQuery
– negotiations.com. The unique aspect of this site is that it’s entirely
static, so all dynamic functionality had to be implemented using AJAX. Git

The site is also very old (around 2005), and many developers had MySQL
worked on it before me, so I often had to spend a lot of time rewriting HTML & CSS
legacy code.

WordPress Developer at PineDev Studio, Kharkiv
PHP
2018 — 2022
I worked on various WooCommerce-based online stores for an Italian JavaScript
client - erbacipollina.it. Examples: esssecaffe.com, italiqa.it, pataro.it, Node.js
zorbas.it, medusa-regnoli.it.
React
I also participated in the development of the IoT startup dimo.org. The
Nest.js
key aspect of this project was the use of GraphQL for data handling.
Docker
I also built an advertising marketplace for media from scratch for a
U.S. startup. Some interesting features included a complex reservation TypeScript
system, the ability for users to upload files to selected media, partial
payments for items, presentation generation from purchased items
using the Google Slides API, and much more.

I also built websites for a security company in Kharkiv (-
ohorona-bezpeka.com) and a travel agency. Notable features included
two language versions (Ukrainian and Russian) using WPML and a
multisite setup for different cities.

Fullstack Developer at Helems
2017 — 2018
I worked on a startup that used WordPress purely as a headless CMS,
similar to Strapi or Sanity. It was a big project that included a WordPress
plugin as well as a separate service that connected to the plugin. The
service itself was built using React and Node.js.

WordPress Developer at WPMentor
2016 — 2017
Worked on a platform where users could find top WordPress
developers. It included a personal account (separate for clients and
developers), project publishing, Zoom integration for video calls,
payments, and more.

Fullstack Developer at JSHub
2015 — 2016
I created an interactive platform for learning JavaScript from scratch,
featuring a built-in code editor, auto-checking tasks, real-world
projects, and more. The site itself was fully built on WordPress, and
there was a separate Node.js service with an API that managed Docker
containers.

I started with freelancing. Here's the link to my profile:

CodeCanyon. I used WordPress as an admin panel and API with a Vue
+ Nuxt setup, extended the standard REST API, worked with all popular
page builders (including writing extensions for Elementor), performed
refactoring, optimized databases and speed according to CWV, created
bulletin boards, personal accounts, and much more. Below are links to
