What I'm looking for

I'm looking to build scalable, secure cloud-native systems, lead technical delivery, and mentor teams in collaborative Agile environments.

At Byrsa-Tech, I lead cloud infrastructure migrations for Java microservices, moving 8+ services to Scaleway Kubernetes and reducing deployment time by 70% through Jenkins CI/CD pipelines.

I architected OAuth2 and RBAC for Defmarket, a benefits platform serving 10,000+ users, while improving API response times by 35% through query optimization and caching. I also integrated Stripe payment processing for secure, reliable high-volume transactions.

I delivered a centralized OAuth2 authorization server that secures 5+ production applications and handles more than 50,000 authentication requests daily, using RabbitMQ for asynchronous communication.

Beyond backend delivery, I build full-stack and interactive products, including a multi-role timesheet platform, a Kubernetes YAML generator, and a Unity/C# virtual museum game with voice-activated exploration. I enjoy mentoring teams and delivering practical solutions in Agile environments.
