Projects

Lightweight uptime & TLS certificate-expiry monitoring daemon written in Odin. Checks HTTP(S) targets on an interval and exposes the results as Prometheus metrics on a /metrics endpoint. A raw-TCP metrics server, and cert expiry read via shell-out — no HTTP or TLS libraries.

A fast, minimal desktop viewer and editor for CSV files. Native-like performance via webview technology — no browser, no cloud. Supports in-grid editing, search with match navigation, and file associations for .csv.

In-memory Adaptive Replacement Cache (ARC) with TTL support, background janitor, hit/miss stats, and benchmarks. ARC outperforms plain LRU by balancing recency and frequency.

Logistic regression implemented from scratch in C — trains on CSV data, runs gradient descent, and interprets the outcome with human-readable output. No ML libraries, just math and pointers.

Lightweight macOS utility in C that prevents the screen from sleeping by periodically nudging the cursor. Uses CoreGraphics — no Objective-C, no dependencies.
