Hello there! I'm a cybersecurity practitioner and developer focused on building practical tools that make devices easier to understand, test, and secure.

Most people only notice security when something goes wrong... a suspicious app, a risky permission prompt, an unknown device connection, or strange network behavior. My work is about making those moments less stressful by giving you tools that are transparent, auditable, and designed to do one job well. Whether that job is security, device visibility, or hardware-adjacent automation.

Some of the apps I've built

• IR Blaster - control and test infrared functionality for compatible devices.
• USBDevInfo - inspect USB device details and behavior to understand what's really connected.
• GadgetFS - experiment with USB gadget functionality (hardware-adjacent, low-level).
• TapDucky - a security/testing tool for controlled keystroke injection workflows.
• HIDWiggle - a mouse jiggler built with reliability and clean UX in mind.

What I'm building

• Security-focused Android utilities (open-source)
• Hardware-adjacent Android tooling (USB, HID, device inspection)
• Reliability, performance, and UX improvements (so the tools are actually usable day-to-day)
• Ongoing maintenance: bug fixes, dependency updates, and security hardening

Why I'm asking for donations Open-source work isn't "done" after release. The real effort is the unglamorous part (maintenance, regression testing, supporting new Android versions, reviewing issues, and shipping fixes quickly when something breaks). This is especially true for Android and hardware-related apps, where device differences and OS changes can cause unexpected failures.

Donations help me pay for:

• Development time (new features + fixes)
• Test devices and cables/adapters (Android hardware is fragmented)
• Continuous testing and release work

My commitment

• Open-source first
• No ads, no shady tracking
• Practical features over hype
• Clear changelogs and steady maintenance

If my apps saved you time, improved your workflow, or simply gave you peace of mind, consider supporting my work here. Even a small monthly donation makes a meaningful difference.
