I am open to remote work opportunities, which allow me to bring my expertise to diverse teams regardless of location. My preferred model of collaboration is B2B, as it aligns well with my professional approach and ensures smooth and efficient cooperation. However, I am flexible and adaptable, and I am also open to considering hybrid work arrangements that balance in-office and remote work.

I had the privilege of working closely with Vlad after he joined our team in March. As a backend developer, he not only brought deep technical expertise but also an impressive ability to connect with stakeholders across the company. He was a supportive, approachable, patient and valued colleague. Vlad showed outstanding commitment, often dedicating extra hours to ensure smooth deployments and was always available to discuss requirements or implementation details. Not only did he play a pivotal role in building and managing critical backend infrastructure but he also led the development of our internal CMS with a sophisticated role-based access control system, tailored to both our team and external clients. I have no doubt he’ll make a significant impact wherever he goes next and would be a tremendous asset to any organization!
