SmartOnline
2 years 9 months

CRM for enterprise distributors. Provides services for inventory of warehouses, logistics, analytics of the
activities of a chain of stores, reporting, creation and processing of customer requests, communication of
operators with customers and order executors. Huge monolithic project with a significant part of legacy
code. Earlier projects used Laravel + Backpack to generate UI, then they decided to add Vue for a more
sophisticated and controlled front-end. Main goal was to switch from Backpack. As historically back-end
had full control on UI, and the company wasn’t going to create a front-end team, I created a flexible
system of creating new routes according to JSON config provided by back-end. It covers most of the
functionality of the app (similar routes with various tables and forms), and in order to create a new route,
no changes in front-end are required. But there are also some custom routes like dashboard and
analytics charts.​

Responsibilities:​

-​ Maintenance, refactoring and bug fixing;
-​ Developing new features;
-​ Creating components library;
-​ Developing flexible “constructor” to render new routes from JSON config;​

customers (some campaigns accrue bonuses in case of purchase of certain products that have to be
present in customer’s cash receipt). After signing an important contract with a local manufacturer, it was
decided to switch to React because the core team used it.​

Freelance
3 months

Decided to get back to development and switched to front-end (Vue2). Practiced on small freelance
tasks, but developed a couple of projects from scratch. Among them:
-​ Website for models casting - never knew the domain - had admin cabinet to view and manage
requests, faq and core functionality - quiz for applicants aimed to get all the needed information
about their parameters, experience, lifestyle etc.
-​ Online cinema - mdn.videoprokat.cc - I had to finish work after the previous developer -
developed user cabined, subscription system, added comments and blocks for ads, had some
tasks to fix bugs and improve existing functionality. Also improved Google Page Speed results
from orange for desktop and red for mobile to green for both (95+ - desktop, 90+ - mobile).
-​ Online store - heat-ampermaster.web.app - online store of alternative energy sources, heating
systems and stabilizers. I created both the design and technical part. All the traffic was supposed
to be redirected from external resources as they already had a website on the local marketplace
(amdp.com.ua), so that no SEO-optimization and SSR was used, and it was hosted on free
Firebase hosting. But this website was supposed to give customers more information about their
products and provide all significant information about their needs via special form, which is
dynamically generated from json config.​

Responsibilities:​

-​ Creating design;
-​ Creating and developing main application architecture;
-​ Deployment to Firebase and paid hostings;

Company name under NDA
2 year 9 months

Huge conglomerate of companies based in the US. Provided outsourcing services and developed and
maintained 14 start-ups, a small social network used mostly within the subsidiaries.
I was hired as a full-stack developer to maintain existing projects and develop new ones. Most of the
projects were static corporate websites, there were 2 WordPress based websites and 2 websites with
custom admin panels, where I had luck to try PHP. Later we started developing the second version of the
social network powered by Symphony and Vue, and its mobile versions (Swift & Kotlin), but I joined the
project already as coordinator of both teams.
The last website was supposed to track COVID rates according to open data from WHO, display them in
various ways on maps and charts powered by d3. Unfortunately, I was not familiar with frontend
frameworks and built it with jQuery, though I managed to make it process and display tons of data
soothly.
While working in the company, I had luck to try DevOps (1 year) and then switched to SRE and held the
position of manager of the DevOps team. This experience was possible thanks to the outsourcing
direction of the company. One world-wide event organizer and ticket distributor was bought by another
and we had to support migration of the platform as a line-2 & 3 tech support team.​
