PlainLink
Local-first link cleaner for macOS
PlainLink cleans tracking parameters from copied URLs at the system clipboard level, without requiring a browser extension. I built its core engine and CLI in Rust, paired it with a native Swift/AppKit menu bar app and user LaunchAgent, and designed a conservative, fixture-tested community rules format that preserves unknown parameters by default.

Founder & Lead Developer
AussieLK is a request-based sourcing platform I founded to connect Australian products with customers in Sri Lanka. I designed and built the full platform architecture, including authentication systems, encrypted request workflows, payment integration, admin tooling, audit logging, and infrastructure deployment.
Self-Hosted Infrastructure
Privacy-focused VPS infrastructure featuring SearXNG, Forgejo, WireGuard, Dockerized services, reverse proxy routing with Caddy, hardened firewall rules, and production uptime monitoring.
P.A.T.H.
GPU-accelerated compute research project built with Apple Metal, exploring deterministic high-throughput prime computation and scalable segmented sieve execution on Apple Silicon hardware.
