    In my role, I plan and coordinate product development initiatives, defining the technical strategy and ensuring that engineering efforts are aligned with overall business objectives. I work closely with clients to assess their requirements and design scalable, effective solution strategies. This includes developing data-integration interfaces for ERP systems and external services such as Pipedrive, which enhances data availability and minimizes manual processes. I also build embedded Power BI solutions leveraging various Azure services, enabling secure and efficient analytics workflows for enterprise customers. To improve operational efficiency, I automate infrastructure provisioning using Ansible and Kubernetes, significantly reducing deployment times and increasing system reliability. Additionally, I mentor and train team members, contributing to higher code quality and continuous technical growth within the team.
