About Me

I am a Backend Software Engineer specializing in production-scale APIs and distributed systems. With 1+ years of hands-on experience building financial technology systems that handle real money and serve real users, I focus on creating robust, scalable backend services using Java, Spring Boot, and microservices architecture.

My expertise lies in financial technology and payment processing systems. I've architected and deployed distributed microservices supporting thousands of concurrent users, optimized AI services by 87%, and maintained 99.99% system availabilityin production environments. My experience includes PCI-compliant transaction processing, Apache Kafka event streaming, and cloud-native deployments.

I believe in performance-first engineering and clean architecture. Whether it's reducing response times from 312 seconds to 41 seconds or building cost-efficient systems that run on $0/month infrastructure, I approach every problem with a focus on measurable results and operational excellence. I thrive in Agile environmentsand believe in the power of collaboration and code reviews.

Currently graduating with distinction (4.84 CGPA) from Uniwersytet WSB Merito Poznan, I'm excited to apply my financial systems expertise to new domains and scale challenges. I'm passionate about building backend infrastructure that powers mission-critical applications and eager to contribute to teams that valueengineering excellence and technical innovation.
