Worked as a Software Engineer at Konsol Studio, contributing to the development of modern, scalable, and production-ready web applications and digital products. I was involved throughout the software development lifecycle, from translating business and technical requirements into functional solutions to implementing, testing, optimizing, and maintaining application features. My work included designing and developing robust application architectures, building reusable and maintainable software components, integrating APIs and backend services, implementing complex business logic, and ensuring reliable data flow between different parts of the application. I focused on writing clean, efficient, and scalable code while maintaining a strong emphasis on performance, usability, and long-term maintainability. I collaborated closely with designers, developers, and project stakeholders to transform concepts and prototypes into polished digital products. I also contributed to debugging, performance optimization, technical improvements, and the continuous refinement of existing applications, helping deliver reliable software solutions that met both technical requirements and business objectives.
