About Stan
With 20 years of experience in software development, I bring broad expertise in designing, building, and delivering complex software solutions across the full lifecycle—from backend systems and microservices to scalable architectures and DevOps practices.
I have deep proficiency in modern technologies and platforms, including Java/JEE, Spring Boot, Camunda, RabbitMQ, Docker, and Kubernetes, while demonstrating a proven ability to rapidly master any new technology, framework, or tool—often becoming a go-to expert within weeks. Throughout my career, I have consistently adapted to emerging languages, ecosystems, and infrastructures with speed and precision.
I think in terms of robust, scalable architectures, always aligned with technical excellence and business objectives, and deliver tailored solutions that meet both immediate and long-term needs.
As a certified ScrumMaster with extensive hands-on experience in agile methodologies, I effectively guide teams, streamline processes, and ensure high-quality, on-time delivery—whether contributing as a developer, architect, technical lead, or consultant.
I am ready to take on any role in the software development process, bringing stability, rapid learning capability, and a relentless focus on results.
