NNavnita

Real-time street parking finder for Melbourne CBD, built on live City of Melbourne sensor data — Rust/Axum API over PostGIS, Redis-backed spatial cache, React Native app with turn-by-turn nav. Native CarPlay/Android Auto is deliberately shelved: it needs an Expo bare-workflow eject, so it waits until usage justifies that maintenance cost.

Self-hostable voice-AI agent framework — bring your own LLM, speech, and telephony keys, run for the cost of a phone number. Each stage (STT, LLM, TTS) sits behind a small adapter interface, so switching providers is a config value, not a rewrite.

Interactive encyclopedia of the ISO 20022 payments core — 19 messages across pain/pacs/camt/remt/head with annotated field trees, legacy SWIFT MT field-level mappings (including the gaps in both directions), and CBPR+/SEPA/NPP/Fedwire scheme overlays. Authored as JSON and inlined into a single dependency-free page at build time; CI fails if the committed build drifts from the data.

A todo list you don't get to choose from — each list is a jar, each item a folded note you draw at random, then put back, mark done, or bin. Rust compiled to WebAssembly, with the watercolour artwork generated procedurally as SVG filters and rasterized once per colour rather than shipped as assets. Local-only: no accounts, no server, nothing uploaded.

Visual rule-engine studio — WYSIWYG JDM decision-graph editor with live trace overlay and audit history, backed by a Python engine wrapping GoRules Zen.

Config-driven ML library for triaging false-positive sanctions alerts (Fircosoft-style hit lists) — an XGBoost + SHAP classifier and a RIPPER rule miner learn from analyst dispositions, no LLMs in the runtime, every decision auditable.

Rust chess engine with bitboards, alpha-beta search, and iterative deepening — compiled to WebAssembly for browser play.

Logseq plugin that auto-migrates unfinished TODOs into today's journal page.

VS Code extension providing syntax highlighting for Brainfuck
