Technology enthusiast focused on fintech, payment systems, and secure digital infrastructure.

About Me

I work across the full spectrum of card payments, ISO 8583 messaging, EFT switches, EMV personalization, and SoftPOS technologies.

My projects span both consumer-facing apps and enterprise-grade payment platforms, aiming to simplify complex financial systems through efficient architecture, localization, and seamless user experiences. Iā€™m especially passionate about building tools that empower engineers ā€” from ISO simulators and PIN block calculators to full-stack payment SDKs.

I take pride in working on solutions that help modernize financial services in underserved regions by combining deep technical knowledge with a clear understanding of local market needs.
