What I'm looking for

I am looking for a role that challenges me technically and offers opportunities for growth in a collaborative environment.

As a Senior Backend Engineer with over 7 years of experience, I have honed my skills in designing, building, and maintaining scalable backend systems using a variety of programming languages including Node.js, Python, Go, Java, and C#. My expertise lies in developing microservices and RESTful APIs, as well as integrating with cloud platforms like AWS and Azure. I have a proven track record of enhancing performance, security, and developer productivity through clean architecture and modern DevOps practices.

In my recent role at Matomo, I successfully revamped the backend infrastructure by migrating from REST to gRPC, resulting in a 35% increase in data processing speed and a 25% boost in system scalability. I also led the migration of legacy authentication systems to AWS IAM, which centralized user management and reduced operational overhead by 40%. My commitment to continuous improvement and collaboration has driven significant enhancements in system reliability and performance across various projects.

I am passionate about leveraging technology to solve complex problems and am always eager to learn and adopt new methodologies. I thrive in dynamic environments where I can contribute to innovative solutions and help teams achieve their goals.
