Production projects
- Headless CSV Ingestion Engine Classic elekcsv Keeping parsing, compiled-validator generation, fuzzy column mapping and bitmap error tracking in one dependency-free core package lets every UI framework reuse identical import logic instead of six separate implementations.
- Local AI Voice Cloning & Speech Studio Hybrid VoiceStudio Heavy model work stays in a Python FastAPI backend with a pluggable, hardware-aware engine registry. Desktop, web, MCP and remote-worker clients all use the same local API, so voice models run on the user's own GPU without a cloud dependency.
- Local LLM Inference Engine & Hardware Profiler Hybrid Magnitude Performance-critical inference sits in a Rust workspace around vendored llama.cpp, while the app, CLI, agent and model management live in a Bun + Effect TypeScript monorepo. The native engine can be pinned and benchmarked on its own while the product layer changes quickly.
- Workflow Automation & AI Orchestration Hybrid Activepieces A queue-backed API/worker split on Fastify, PostgreSQL and Redis lets executions scale horizontally, while a typed pieces framework and isolated execution keep community integrations safe to load at runtime.
- Conversational Form Builder AI-agent Typebot The editor and the chat runtime are separate Next.js apps built from one Dockerfile, so the public chat runtime scales apart from the editor. Bot logic, Forge integration blocks and the Prisma schema live in shared Bun workspace packages that both apps use.
