What I'm looking for

I seek technical leadership roles in fintech or banking-focused teams where I can lead secure multi‑cloud architecture, optimize infrastructure, and deliver compliant payment solutions.

I am a Backend Developer and DevOps specialist with over 5 years focused on digital transformation in the financial and banking sector. I design secure, cloud-agnostic architectures and lead multi-cloud migrations while ensuring regulatory compliance.

I have led migrations across AWS, Azure and OVH, rebuilt CI/CD pipelines, and implemented distributed messaging systems to improve reliability and reduce deployment time by 40%. I also executed database and storage migrations with zero data loss.

My work has delivered measurable results: 25% increase in transactions after implementing a compliant mobile payment system, 40% performance improvement from API refactoring, and a 15% reduction in cloud costs through optimization. I manage multicultural teams and emphasize proactive automated testing to reduce critical bugs.

I bring hands-on expertise in containerization, Terraform, monitoring (Grafana, Zabbix, Prometheus), and backend development with Python and Django, alongside experience integrating payment gateways and push notifications to build resilient, compliant fintech systems.
