Develop media content distribution platform, from client applications (Android AOSP (C ), Android SDK (Java, Kotlin)) to head-end services (Go, Java, AWS)

Develop order management automation system in apparel retail domain as part of distributed international team - Java - Spring - OpenShift - RH Linux - Docker - Bash - Python Develop banking automation system as part of distributed international team main technologies: - Java - Spring - RDBMS Oracle - RH Linux - TeamCity - bash

Develop web-based resources as part of distributed international teams. Participate in infrastructure support development as infrastructure/sysOps team member. Some interesting tasks examples: - develop CLI tool for fast Infrastructure-as-a-code (terraform) configuration files generation (Go, bash): when developers need to create infrastructure for their freshly-developed service they don't have to write all the configs manually but can just type several console commands - participate in development of notification tool for code lifecycle system (Go): integration between VCS repo, CI service, messengers etc main technologies: - Go - Java - RDBMS PostgreSQL, MySQL - AWS - Terraform - Spring, Hibernate, JBoss/WildFly - of course, bash && Python to write ops automation tools Working environment: Agile with Scrum elements

Develop web-based ETL system as part of small distributed team. Main technologies: Java, Spring ecosystem, PostgreSQL, React, different types of DBMS as auxiliary storages Working environment: Agile/Kanban without Scrum approach.

Develop front-end part of large business platform as a part of large distributed international team. Main technologies: - AngularJS 1.3/1.5, Angular 2/4 - NodeJS as a part of auxiliary server parts of front-end application - occasionally React - Docker - Jenkins CI - Amazon AWS Working environment: Agile/Scrum Some interesting tasks examples: - develop and maintain web applications (SPA-like platform-integrated AngularJS 1.x apps based on rich back-end API) in part of front-end - sometimes, when basic server API functionality is not enough to implement required business logic, develop server middleware in nodejs - cover AngularJS 1.x / nodejs code by unit tests (usually Jasmine / Jest appropriately) - develop dedicated Angular4 web application based on REST API - solve SPA immanent problems like search engines indexing (as a last resort server-side pre-rendering using headless Chrome implemented) - cover code by Jasmine/Karma unit tests, Protractor end-to-end tests

Develop microservices-based distributed system (a kind of corporate VPN) as part of small remote team. The main purpose of system is collect full network traffic statistics and optionally filter/change some parts of traffic. Main technologies: - Go (previously Glide and currently dep as dependency manager, Ginkgo/Gomega as testing framework, some open-source packages like gin are used, much of codebase is own) - Clickhouse DBMS, PostgreSQL DBMS - NATS for messages queueing - Docker - Jenkins CI - Occasionally JS, Groovy (as a part of Jenkins plugins) Working environment: Agile/Kanban with kind of "soft scrum" some interesting tasks examples: - develop fast IP packets matcher (match by src/dest address) - Participate in development of HTTPS hijacker (MITMer) - parse IP packets - filter HTTP traffic using both as IP parsed information like in/out addresses/ports and server names as HTTP headers and in some cases marker sequences occurencies in HTTP request body

Old was on jQuery and plain HTML. back-end: PHP, MySQL. An API for mobile app was developed and supported. features: deep integration with the third party billing system, mailing system and with the user notifications aggregator that sent them to pushnotifications service. Later the app's own pushnotification engine providing connections with pushnotifications service was written on common PHP.

Develop Web sites mainly in LAMP stack. Perform integration with different Web services like payment systems, social networks, geographical information services etc. Main technologies: - Back-end: LAMP (PHP+MySQL/MSSQL/PostgreSQL), CodeIgniter, Laravel, Symfony, CakePHP. - Front-end: HTML+CSS+js, jQuery, Bootstrap. most interesting tasks and projects: *** Much small tasks with different maps services like Google Maps, Yandex.maps, 2GIS, 4geo, OpenStreet - mainly map API integration and data display customizing, also often back-end response customizing in accordance with front-end display requirements. Mainly with LAMP stack, rarely with c#, ASP.Net, even with MS JScript *** Much small tasks with different payment gateways like PayPal, QIWI, etc. Mainly with LAMP stack, rarely with Node, ASP.Net *** Some tasks of websites Integration with quick-payment system providing quick payment using QR code for users have an installed application on their smartphones *** Web site for artificial decorative stone producer company front-end: jQuery, bootstrap, Flash back-end: CMS OpenCart *** Drugstores search service front-end: bootstrap, jQuery, Yandex maps API back-end: CakePHP, MySQL *** web site for furniture producer company front-end: jQuery, jQuery UI, jQuery plugins back-end: CMS Drupal, MySQL *** Market stores search servise providing users an ability to search where they can buy specified products on the Ukrainian markets and see found shops on the map front-end: jQuery, Yandex.maps, Bootstrap back-end: CodeIgniter, MySQL *** web site for furniture providing company in Kazakhstan front-end: jQuery, jQuery UI, jQuery plugins, much AJAX functionality in the administration interface back-end: self-written CMS on PHP+MySQL *** improvements of realty aggregator site functionality in part of map-based displaying of realty objects in accordance with specified pages and search criterias front-end: jQuery, Yandex.maps back-end: Joomla!
