Brain is a Git-backed Markdown knowledge base. Brain UI is the Rust/Leptos control plane on top of it. This is the system, the connection between the two halves, a real config-driven taxonomy, and the honest reasons I’m putting the core in the open.
How I rebuilt my personal site as a versioned, reproducible static-site system with clear separation between landing page, blog, generators, and a small Go API companion.
Zero Grappler is a small no_std crate that applies a data-pipeline mindset to embedded ML: three traits, two async tasks, compile-time buffer sizing, zero allocations. This post is about the design choices — not yet a hardware report. The Pico 2 W smoke test on real silicon is still ahead of me.
Two Rust projects, one conceptual divide. Ares fetches arbitrary web pages and uses LLMs to extract structured data; Ceres harvests metadata from CKAN portals and indexes it semantically. Together they show what it looks like to move from scraping scripts to production data pipelines.
A design story of dataprof: why I built a profiler around Apache Arrow, how it changed the architecture, and how this journey led to contributions to arrow-rs’ Parquet reader.
A technical exploration of async/await in Python and Rust: how the same syntax hides completely different execution models, with practical examples from contributions to Tokio and Python projects.
A deep dive into Mosaico, the robotics data platform written in Rust: client-server architecture, semantic ontologies, data-oriented debugging, my journey within it, and the integration with Data Contract Engine.
Ceres is a semantic search engine for CKAN portals. Built in Rust with Tokio and PostgreSQL+pgvector, it bridges the gap between how people search and how public administrations name their datasets.
Polars completes the Rust data engineering ecosystem: lazy evaluation, Apache Arrow, and native Iceberg V3 integration for performant analytics that compete with distributed clusters. The third pillar of the RisingWave + Lakekeeper + Polars stack.
An exploration of Lakekeeper, the Iceberg REST catalog in Rust that completes the data engineering ecosystem: enterprise security with vended credentials, multi-tenancy, and RisingWave integration to build streaming lakehouses without JVM
