What I'm looking for

I seek a role that fosters innovation and collaboration, with opportunities for growth.

I am a dedicated Senior .NET Developer with extensive experience in building microservices-based architectures. Currently, I am working with Keyloop, where I design and implement scalable microservices, ensuring high data flow and security. My focus on best practices for distributed data management has significantly improved query performance and overall system maintainability.

Previously, I contributed to Bytespack Sp. z o. o., where I led the development of a backend solution for cost and carbon estimating in construction projects. My role involved designing microservices and integrating various communication protocols, including gRPC and RabbitMQ. I have a strong background in collaborating with cross-functional teams, including UX/UI, to ensure the validity and effectiveness of our solutions.

With a Bachelor of Engineering in Internet Technologies and Applications, I have honed my skills in organizing junior developers' work and conducting code reviews. I am passionate about leveraging my technical expertise to create innovative solutions that drive business success.
