What I'm looking for

I’m looking for a team where I can build secure, cloud-native products and apply AI to real-time decisioning. I want to own end-to-end features, collaborate across disciplines, and improve performance, reliability, and compliance.

I’m a Senior Full Stack Engineer with 10+ years building scalable platforms across FinTech, Healthcare, and AI. I develop advanced AI-driven applications and integrate machine learning models into real-time, decision-focused systems that optimize business outcomes.

In recent roles, I’ve built multi-PSP payment gateway experiences with intelligent routing and AI-powered recommendations to improve success rates and reduce transaction failure windows. I also develop real-time dashboards and monitoring systems for performance tracking, API inspection, and fraud policy debugging.

I bring deep expertise in microservices, cloud-native architecture, and secure system design—especially where privacy and compliance matter. From HIPAA-aware telemedicine backends to high-throughput payment endpoints and WebRTC stability work, I focus on building resilient, secure, data-driven products that teams can rely on.
