Maksim Biarynchyk

Continued driving feature study within team. Was considered an expert in some product areas, and maintained responsibility for their quality. Developed new technical competences during onboarding for a new Cloud Native project, which was eventually cancelled.

• Cloud Native concepts
• Docker, Kubernetes, Helm basics
• Golang, Python basics
• YANG
• 5G Concepts and Architecture basics
• Telecom Subscriber Data Management basics

Continued development as a feature implementation proposal writer.

Participated in complex multi-phase feature implementation, requiring 5 teams collaboration.

• Shifted towards system level architecture, maintaining lower level knowledge.
• Developed complex, system level feature in collaboration with multiple teams.
• Provided technical expertise for system areas owned by team (previously developed within team) for other teams, including code reviews, workshops, implementation proposal reviews for trouble reports/features.

Became Study Driver for features in team. Wrote detailed feature implementation proposals and held review/approval online sessions.

• Drove development of cluster-aware distributed software component (written in C++) that supports IMS Application Servers in implementing licensing solution based on number of active users.
• Used artifactory for releasing new product versions.
• Performed memory optimizations based on optimal data structures selection and copy avoiding (move semantics).
• Development for Linux-based distributed system (OpenSAF-based middleware).
• TIPC for distributed service components communication in cluster.

Progressed in the telecom project participating in complex features as a C++ designer. Worked in a collaborative team combined of two teams located in different countries for complex feature implementation to support interworking with originating network lacking some modern capabilities.

• Intensive C++ development
• Team collaboration
• Complex feature planning

Onboarding for the C++ Telecom project - IMS Application Server. Getting general understanding of the IMS Architecture, protocol stack (mainly SIP), call flows. Investigated and solved lots of Trouble Reports and was writing functional test cases for first features.

• Telecom/IMS
• Functional Testing with TTCN-3
• C++
• Jenkins CI
• Gerrit code review
• Brief understanding of System Testing (System stability/capacity/upgrade)

Participated in internal educational project with other newbies led by few experienced people.

• Gained basic knowledge of Web app development
• Scrum, Jira
• Java (Spring)
• Angular
• PostgreSQL
