# Projects – Daniil Hirchyts

- [Stream – Torrent Streaming on Low-End Android TVs](https://hirchyts-daniil.me/projects/stream.md): Built an Android TV app that plays torrents through its own Rust BitTorrent engine, keeping a moving 256 MiB window of the film on the TV, so a 1 GB stick needs no streaming server, account or backend.
- [AgentOps Control Center – Human Approval for Agentic AI](https://hirchyts-daniil.me/projects/agentops-control-center.md): Built a control plane for agentic AI in accounts payable, using backend policy, a human approval gate and a transactional action ledger, so that an approved action runs exactly once and every step is audited.
- [Turbofan Failure Prediction – How an ML Solution Gets Built](https://hirchyts-daniil.me/projects/turbofan-failure-prediction.md): Built a failure-alarm model on NASA's turbofan fleet simulation, using engine-level validation and a selection rule fixed in advance, catching 21 of 25 engines close to failure with 3 false alarms.
- [Stock Coverage – Clinical Trial Supply Management Platform](https://hirchyts-daniil.me/projects/clinical-stock-coverage-simulation.md): Implementation of a data-driven architecture for managing clinical investigational products, transforming heterogeneous IRT exports into an operational simulation tool for preventing stock-outs, reducing waste, and aligning with GxP requirements.
- [Kokodi Pogz – A Scalable Telegram Gaming Platform](https://hirchyts-daniil.me/projects/kokodi-pogz.md): Led a Telegram Mini App game with Next.js/TypeScript, bot webhooks + payments, MongoDB + caching, and cost-optimized production deployment.
- [Text Prediction System – The First Rung Under Every LLM](https://hirchyts-daniil.me/projects/text-prediction-system.md): Built a next-word prediction system from first principles in Scala 3, using n-gram counts, a trie and stupid backoff, to measure where counting stops working and what language models had to change, reaching about 20% top-3 accuracy in English on held-out text.
- [Logarithm Finance – Advanced DeFi Platform](https://hirchyts-daniil.me/projects/logarithm.md): Led frontend delivery for a DeFi vault UI: wallet onboarding, transaction UX, and performance-focused analytics.
- [Gradhire – Student Internship Platform](https://hirchyts-daniil.me/projects/gradhire.md): Academic full-stack internship platform with LDAP + email auth, RBAC, and a PostgreSQL workflow model built for reporting.
- [Pixel Battles – Web3 Pixel Art Game](https://hirchyts-daniil.me/projects/pixel-battles.md): Built a real-time collaborative canvas and battle engine with a WebSocket backend, service separation, and performance-focused rendering.
- [The Merge World – Building a Web3 Strategy Game Platform](https://hirchyts-daniil.me/projects/the-merge-world.md): An MMO economic strategy game that allows players to manage their own empire with advanced features like token purchases and an interactive map.
- [Posers & Wolf Game – Website and Character Customizer Development](https://hirchyts-daniil.me/projects/posers.md): A case study on developing a marketing website and character customization tool for NFT collections.
