Commercial and open-source projects built with an engineering focus: simple architecture, readable code, and systems that stay up after deploy.
Mobile/desktop app for configuring agronomic model parameters and simulating root growth.
WhatsApp bot that OCRs and categorizes receipts via an LLM, with a live expense dashboard.
Frontend for iperf3 that runs multiple simultaneous clients to measure aggregate throughput.
LD_PRELOAD-based memory-leak tracker for Linux; injects itself via memfd_create.
Web/PWA app for tracking rubber (latex) production weighings on a plantation, replacing a spreadsheet-based log.
CPU-only realtime transcription and speaker diarization web app, no GPU or terminal mode required.
On Fedora with firewalld, `tailscale up` can leave the tailscale0 interface unassigned to any zone, silently dropping real traffic while tailscale's own control-plane pings keep working.
A CIFS globalmount on a TrueNAS SMB share went stale on every k3s node at once, and csi-driver-smb kept bind-mounting the dead handle into every new pod — fixed with noserverino, a real mount-stat liveness probe, and a DaemonSet that force-unmounts stale CIFS globalmounts.
Docker sets the kernel FORWARD chain policy to DROP and leaves DOCKER-USER empty, silently killing traffic from libvirt's default NAT network even when firewalld and libvirt are both configured correctly.
