Tomasz D.

Senior Java Developer

With a rich background in software development, I specialize in Java and related technologies. My experience spans teaching, back-end development, and architecture, involving diverse projects from large-scale platforms to tailored client applications. Currently, I focus on designing and deploying cloud-based back-end solutions with a specialization in serverless architecture, security, integrations, and databases. I've collaborated with global corporations, provided consultancy services, and freelanced for SMEs and startups. My project portfolio ranges from high-traffic e-commerce applications to data-centric and cutting-edge solutions like low-code platforms and AI-integrated tools. Leveraging my extensive experience, I not only offer technical expertise but also provide valuable business insights to clients, advising on the strategic aspects of their applications. Moreover, I hold AWS certifications and boast a strong educational background with degrees in Computer Science and Organization Management.
