Work experience

Software Engineer

from 02.2016 to 07.2025 (9 years 6 months)
GBSFO, Одеса (IT)

Project: LiveNX — enterprise analytics platform
Scaled a complex analytics platform handling large volumes of real-time data by designing a modular Angular architecture separating UI, state (NgRx/Akita), and data layers → improved maintainability and reduced feature delivery time by ~30%
Faced performance bottlenecks in high-frequency data dashboards → optimized Angular change detection and implemented RxJS-based reactive streams → reduced UI rendering latency by up to 40% and improved responsiveness for large datasets
Modernized a legacy AngularJS application to meet growing product complexity → contributed to migration to modern Angular (v12+) using best practices (lazy loading, modularization) → enabled faster development cycles and improved long-term scalability
Addressed duplication and inconsistency across multiple UI modules → extracted shared UI patterns into reusable Angular components and libraries → reduced duplicate code by ~25% and accelerated development across teams
Ensured consistent and scalable UI styling across a large application → built a structured SCSS architecture (variables, mixins, utilities) → improved design consistency and reduced styling bugs
Bridged gaps between frontend and backend for complex data workflows → collaborated with backend teams to refine API contracts and data structures → reduced integration issues and improved data handling efficiency
Improved code quality and team productivity in a distributed environment → conducted code reviews, mentored developers, and enforced best practices (RxJS patterns, clean architecture) → raised overall code quality and reduced production defects
Supported development of data-heavy visualizations and analytics features → worked with D3.js/Highcharts to render complex datasets → enabled actionable insights for enterprise users
