Ilya.usov

Worked on reliability improvements for JetBrains repositories, focusing on bug fixes that enhanced remote development and protocol stability. In JetBrains/ideavim, addressed incorrect template state handling by introducing a client-side live template highlighting check, ensuring accurate template detection during remote sessions and improving user experience. For JetBrains/rd, implemented cross-language message length validation in both Kotlin and C#, preventing OutOfMemory crashes by capping message sizes and logging oversized messages as errors. Demonstrated skills in Editor API, error handling, and system design, with a methodical approach to debugging and code changes that improved stability and consistency across distributed development environments.
