What I'm looking for

I’m looking for international opportunities in fintech and payments engineering—focused on secure, hardware-integrated transaction systems. I’m open to relocation and can support visa sponsorship, aiming to build reliable high-availability solutions.

I’m a Software Engineer focused on building secure, high-availability fintech systems in C/C++—especially ATM/POS applications and low-level hardware integration via CEN/XFS. I’ve delivered solutions deployed across thousands of devices globally, supporting real-time transaction processing.

In my current work, I build and maintain high-performance EFTPOS (POS) applications, enabling secure, low-latency payments across large retail environments. I implement EMV Level 2 flows and design ISO 8583 messaging for multiple acquirers and issuers, including full transaction lifecycle handling.

Earlier, I developed large-scale ATM and smart safe software, integrating cash dispensers, recyclers, card readers, PIN pads, printers, and sensors across multiple vendors. I also built a hardware abstraction layer (HAL), applied OpenSSL-based cryptography for secure communications, and reduced device testing time by 80% while cutting issue diagnosis time by 70% using automated diagnostic reporting tools.

My background also includes embedded systems and robotics research, where I modeled and simulated robotic systems with MATLAB and designed a custom 3D printer integrating embedded control and hardware components. I’ve also worked as a technical instructor for embedded systems and programming, bringing practical hardware-focused engineering to others.
