My library
Data & automation
CSV quality checks
A local Python tool that checks columns, types, uniqueness and constraints, then produces a JSON report without copying cell contents.
Web & APIs
Node SSE stream
A server-sent event stream with a progress interface, client cancellation, heartbeats and bounded handling of slow connections, without a framework.
Web & APIs
Signed Node webhooks
A Node.js webhook receiver with HMAC signatures, raw-body verification, bounded replay protection and local tests without runtime dependencies.
Rust & Go
Go Durable Worker
A persistent local Go queue with leases, delayed retries and terminal states. A text handler demonstrates the full lifecycle without external services.
Rust & Go
Go JSON API
A Go JSON API with token authentication, pagination, ETag versions and graceful shutdown. Tasks stay in memory and tests cover concurrent access.
Rust & Go
Rust Local HTTP API
A local Rust API with health checks and an in-memory notes CRUD tested over real sockets. An educational foundation with deliberately limited HTTP support.
Rust & Go
Rust Text CLI
A Rust tool for line and word counts, Unicode text search and JSON output, with no application dependencies.
Artificial intelligence
AI response evaluation bench
Compare responses against references, check explicit constraints and optionally connect a local Ollama server.
Artificial intelligence
Local document search
Index text and Markdown documents, then find useful passages with TF-IDF and no remote service.
Artificial intelligence
Trainable text classifier
Build a Naive Bayes classifier, train it on your categories and measure results on separate examples.
Artificial intelligence
Tiny language network
Train a small character neural network, inspect its loss and generate text locally with NumPy.
Web interfaces
Interface Essentials
An original HTML and CSS starting point: a mauve palette, responsive grid, cards and buttons with visible keyboard focus.
