Software Engineer | Full Stack & Mobile | Fintech & Scalable Platforms
Building scalable web and mobile applications
Software Engineer with 5+ years of experience developing production systems, currently working at Gazin Tech on financial platforms and large-scale e-commerce solutions.
I work across backend services, web platforms, and mobile applications, focusing on authentication systems, payment processing, and scalable architectures.
My professional experience includes:
- Identity & Access Management (IAM)
- Financial transactions (Pix, credit cards, payments)
- High-traffic e-commerce platforms
- End-to-end mobile application ownership
- Cloud infrastructure on AWS and Azure
Most professional work is developed in private repositories, so this GitHub mainly reflects personal, academic, and open-source collaborations.
Real-world systems and research platforms I have contributed to.
