Hi there! I'm Hubert, a full-stack web developer passionate about building practical solutions.
Currently, I develop BlitzyApp – a no-code platform for rapid idea validation – while contributing to open source projects in my spare time.
What defines my work:
- Bridging modern tech (Next.js, T3 Stack, Rust) with proven solutions (.NET, C#, React)
- Specializing in complete applications – from UI to server logic
- Prioritizing real-world usability
- Fearless problem-solver & experimenter:
-
🚀 Built AssistlyApp in 3 hours during a school hackathon
-
🛠️ Created BlitzyApp single-handedly – SaaS platform (design, architecture, development)
-
🤖 Engineered AI Companion – End-to-end open-source backend and web ui for creating ai chatbots:
- Offline-first architecture: Fully local execution (CPU/GPU), zero external API dependencies
- Model support: .gguf models (Llama 2, Mistral)
- Hardware acceleration: CUDA/Nvidia GPUs, Metal (Apple Silicon), OpenCL (AMD/Intel)
- Memory systems:
- Short-term + long-term
- Real-time conversation learning
- Advanced features:
- Roleplay actions via
*asterisk syntax* - Time-aware responses (system clock integration)
- Character cards (.json/.png) with {{user}}/{{char}} templating
- Roleplay actions via
- Deployment: Single binary ≤26MB (Rust) with API and web ui built in
-
🎨 Developed Aichar – Library that helps with creating, parsing and modifying character cards:
- Cross-platform: created character cards work in TavernAI, SillyTavern, Pygmalion, AI Companion
- Universal: Can be used to create character from scratch, read from .json file, .yaml file, can be used to load existing character and even to modify it
- Performance: Hybrid Python/Rust engine (faster processing)
- Downloads: 738k+ peak PyPI downloads
-
🏭 Designed Character Factory – Full-stack AI characters studio:
- Generative pipeline: Stable Diffusion (visuals) + LLM (descriptions)
- Web UI: Intuitive interface for non-technical users
