I've been deep in Summit, a SaaS crypto algo trading platform with AI/neural-network integration — building out mobile responsive shells with Telegram miniapp support, implementing server-authoritative 2FA and session-inactivity locks, adding per-user follow capabilities with balance-relative sizing and order-type controls, enriching backtests with BTC market-regime context and funding-fee modeling, and introducing strategy-level comment fields and LLM token-cost estimates. On the embedded side, I've evolved the j-uni-hid firmware through multiple revisions (v9–v13) for ESP32-S3, adding features like dual-core support, BLE/USB hybrid operation, self-reporting stats, safe serial prints, and a matrix variant, while also building out the companion input-driver Windows WDK kernel driver with event filtering, block predicates, and integration-test coverage.

Alongside these core vectors, I ran a structured research campaign on crypto price-prediction models — over 300 experiments exploring sparse MoE gates, cross-pair features, snapshot ensembles, and temperature scaling to push past the 0.78 F1 ceiling. I built an Android TTS engine supporting multiple Russian voices with pitch control, Vosk/Silero endpointing, and RuNorm rule-based text normalisation. I also reworked the intag2 Windows file-tagging utility with CLI support, MS Store CI/CD pipelines, and Unicode metadata handling, and I overhauled the ozwil-android on-device LLM agent with sub-agent delegation strategies, KV-cache reuse, and model setup wizards. Smaller but notable efforts include a Neovim config migration to the 0.11 API, a YOLO labeler with batch mark mode, and a MynePro e-ink launcher with gesture navigation.
