Kiryl contributed to the Expensify/App and callstack-internal/Expensify-App repositories by focusing on front end and mobile stability, particularly around React Native keyboard handling and dependency management. Over two months, Kiryl delivered features and fixes that improved keyboard interaction UX, enhanced dependency resilience, and ensured build reproducibility. Using JavaScript, TypeScript, and Swift, Kiryl addressed post-rebase stability issues, upgraded UI dependencies for compatibility, and maintained package hygiene for deterministic builds. The work demonstrated a strong grasp of configuration and version control, resulting in smoother user experiences and more reliable releases. Kiryl’s contributions reflect depth in both technical execution and codebase maintenance.
February 2026 — Expensify-App (callstack-internal/Expensify-App): Focused on stability after integration, UX polish for keyboard interactions, and build hygiene. Delivered three core items with clear business impact: - Post-Rebase Stability Fixes to restore functionality after a rebase (commit fb7aee09591ace259cc65a10ea0059d81d8dd923). - Keyboard Interaction UX Improvements by updating dependencies for keyboard animations and pager view, enhancing user experience during input (commit bdea5b43cf344357564944bfc18e399a0ebefebd). - Package-Lock Formatting Fix to ensure a proper newline at EOF for deterministic builds (commit ea426eb4fa6d3a00a62bb8dcf3658b6d26c2ef97). Overall impact: reduced post-merge instability, smoother user interactions, and improved build reproducibility. Demonstrated skills in dependency management, post-merge defect triage, and codebase hygiene for reliable releases.
