Senior Software Engineer - 21589 Outstaffing

Taken a lead role in development of Clawee - interactive online game based on user - IoT-device interaction.

Applicationwasfully refactored to “fresh”codebase, remove legacy undocumented behaviors and increase quality

of user experience (overall application rating growed up to 4.3 from 3.9 stars) and application performancewith:

coroutines, updated architecture (with Unkle Bobʼs Clean architecture as base), modern libraries and development

practicies. Delivered dozens of newfeatures(in time almost every time).

-

Implemented CI based on bitbucket pipelines(multi-build taskwith auto-publish ability),code-style,code-review

and git-flow(upgradedwith respect to ourspecific developmentstyle)

-

Increased stabilitywith Crash/ANR-free sessionsto 99.95% while audience 100% growth asindicator. Decreased

(almost to zero) number of hot-fixesin production related to client issues.

-

Led 2 development teams- Android and IOS. Was managed tasks, human-time resources, release planning and

interactionswith CTO/PO, design and analyticsteams, etc.

Developed a “native” (written in Kotlin) module for React-Native multi-platform client-bank application,

responsible for registration process, using cutting edge Android libraries and components,such asNavigation,

Room, Data Binding, ConstraintLayout, etc.with image recognition parts, like id-card scanning and face

recognition functionality aswell. All UIwas built in non-blocking stylewith Kotlin Coroutines and Android

LiveData component.

Participated in development of messenger-application forsmall and middle businesses(including VOIP,

screen-sharing, all-wayssynchronization) from scratch, using RxJava, WebRTC and latest libraries and approaches

recommended by Google. Was directly involved in architecture and inner protocols development.

-

Also, developed “local” backend server, using Spring/Kotlin, for the above mentioned application to speed-up

developmentcycle. Itwas used for modeling “real” backend (developed by another team) andwas pretty

convenient for debugging and issue-hunting.

◆ Developed an application for data center monitoring. Applicationwas developed from scratch, beginningwith

elaboration ofspecification and requirements. Configured GitLab and TeamCity forcontinuousintegration and

staging. Prepared environment for application deployment. Developed a microservice architecture, data

transformation algorithms, db schemes and protocolsin application. Set up RabbitMQ and MongoDB cluster for data transfer and storing. Developed, tested and deployed all parts of the system, using Java, Kotlin, Spring, JUnit

and Docker, including modulesfor monitoring and alerting (mail and SMS, depending on issue critical rating).
