What I'm looking for

I'm open to full-time, remote, and relocation opportunities.

At THT Space Electrical Company LTD (EPZ), I architect and deliver Flutter applications across iOS, Android, Web, Windows, and macOS, maintaining a 99.9% crash-free session rate across 5000+ active devices. I also developed a desktop SDK for USB and Bluetooth thermal and dot printing, reducing manual print errors by 80%.

I integrated ML Kit and TFLite for a biometric attendance system that replaced manual check-in for 200+ employees, with 95%+ face recognition accuracy. My work also includes Node.js REST APIs, Stripe payments, and native hardware integrations using Method Channels and FFI.

On Grozziie, I worked on smart attendance and printer features, including Bluetooth and WiFi printing. I also created Buildstroms, a Flutter Web platform showcasing 10+ production projects, and mentor junior developers through structured code reviews.
