At Beeline Kazakhstan, I worked on Janymda, a telecom self-service app serving 4M active users across Android and iOS. I delivered customizable mobile and internet plans and self-service features including SIM replacement and additional SIM activation with OTP verification.
I initiated performance optimizations that reduced startup time by 25%, and led the adoption of Tuist-based modular architecture, extracting 5+ independent modules. I also improved CI/CD workflows with Fastlane, GitLab CI, and Danger Swift.
At TechCulture, I modernized a legacy iOS codebase by migrating Objective-C components to Swift and integrated analytics and A/B testing for deXoo. I also built an Objective-C RSS reader as an iOS trainee at EPAM Systems, and created BrushUp, a quiz tool for teachers that generates questions with Gemini AI.
