## Person

- **Name**: Denis Proleev
- **Level**: Middle
- **Summary**: A frontend app engineer (middle) who builds small-to-medium single-page applications with a focus on client-side audio tooling. The strongest proven skill is implementing a client-side audio pipeline that fetches TTS from third-party AI services, trims and concatenates audio, caches clips in IndexedDB, and encodes MP3s for download. There is limited evidence of component-based architecture, automated tests, advanced accessibility attributes, or explicit request cancellation and race-condition handling.
