Summary I have a big experience in versatile mobile projects and tasks on any stages, built from scratch to full construction, support/bugfixing/refactoring in any modern/legacy clean/dirty code with high efficiency. Four Flutter projects (both platforms), over 40 Android and 5 iOS projects are completed so far. Work Experience ● Mar 2021 - [Now]: Flutter developer [IT X100 Group, remote] (Ukraine-multinational, 175+ employees https://joinitx100.com). The “VENUS” project: multi-brand cross-platform mobile app for food delivery (Flutter) with fully customizable UI, configurations, and content, managed by own web-based CMS (separate project, Flutter too). The goal is to replace old native apps and to connect new brands with ease. I took an active part starting from the very beginning of the project and touched almost every feature and aspect of the system’s architecture. We were working in a Scrum team, 3 Flutter developers with a dense and active code-review process of each other. This project is making use of CI/CD and I took some part in that too. Applied architecture approach: ui/domain/data/core layers on BLoCs, one repository for all brands. Together with me, we’ve released 2 brands: Sushimaster and Monopizza, another 5 are in the alpha test stage. Fully configured the process of adding new brands, version updates. Thanks to the new product existent users of apps can get access to new features faster, the new way of scaling a business is ready, and the cost for old versions support is sufficiently reduced. #dart #firebase #flutterbloc #provider #freezed #googlemaps #signalr #nullsafety #ci #cd ● Nov 2020 - Feb 2021: Flutter developer [Gerchik & Co, freelance, remote] (https://gerchik.co). Worked on a mobile learning forex platform (iOS/Android). Students have a set of lessons with tests after every two or three lessons. Fully customizable content and translations managed by own CMS. Lessons in a form of video or custom parsed HTML files to show as native UI. With help of this app the company got a channel to acquire new clients all over the world. #dart #youtube #socialauth #html #provider ● Jun 2020 - 2021 Mar: Flutter developer [freelance, remote] (Russia). It was an idea to prepare an alphabet learning app for kids (iOS/Android). The app design composed for smartphones and tablets contained a lot of graphics, a lot of configurable styles and hot reload of them, a lot of animations and video inserts. The work was done in about ½ but unfortunately, the client denied continuing mobile development based on life circumstances. As a developer and a new Flutter enthusiast, I got the experience to work with things I’ve never touched in other projects. Some screens are made with the help of game engine box2d. #dart #animations #graphics #responsiveui #flame #box2d ● Jul 2019 - 2020 Jun: Flutter developer [VGL Ltd, freelance, remote] (Russia-Ukraine https://www.vgl.su). I’ve developed a whole new mobile version of the company’s product “VGL Patrol” by myself (iOS/Android). This is an app for ordinary employees of security companies and their supervisors - a version like the main desktop product but with some limitations. Its architecture is based on features interactions via streams. For client-server communication, we had to add self-signed SSL certificates to the target platform and that was the reason to implement native plugins. The application is potentially ready to deal with dozens of thousands of records by implementing a thin client concept. With this application, the company got the ability to equip every client with their product and that became an additional source of monetization. #dart #nativeplugins #sqlite #streams #ssl #pagination #thinclient #iap #firebasefunctions #bioauth #responsiveui ● Jun 2018 – 2021 Jan: Android developer [Rapid Square Inc., remote] (USA-Russia, 10+ employees https://rapidsq.com) Support and further development of product application for business card interchange.

I've fully estimated and helped to take several projects, successfully finished active development stages for two government tenders. In conditions of tight communication and co-working with iOS developers I managed to solve some iOS tasks/issues on a legacy Objective-C project. #kotlin #android #mvp #rx ● Jul 2017 – 2018 Jan: Android developer [QuickAppNinja, remote] (Latvia-Russia, 10+ employees https://quickappninja.com) Prototyping, making architecture, development of app templates for further user customization, setting new skins and building .apk files on company servers using self-written scripts in a pipeline. Work with MVP, Ad Networks, drawing on canvas, Gradle. Some of my suggestions were implemented and included into release apps. I generated several ideas for new templates and offered a fresh way on how to build templates, which could be a possible solution for project stagnation and HR problems. #kotlin #lua #cd ● Jan 2016 – 2017 Jun: Android developer [project based, remote] Test of a business idea: could it be profitable to stamp template apps, completely redesigned and with rewarded video ads included? I created over 50 template-based (4-6 per template) apps/games for Android, about 30 of them are based on Chupamobile purchased Unity3D games. That turned to a successful and fast development cycle, restyling, ads library injection via java plugin. Many games were not only restyled, but their logic (C#) and logic of ads showing were also changed. #java #unity3d #ads #csharp ● Mar 2014 – 2015 May: iOS developer [freelance, remote] Personal interest to get familiar with a competitive platform technology, gain new experience, and broaden my mind.
