What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and continuous learning.

I am a passionate Full Stack Engineer with over 7 years of experience in creating scalable and efficient web solutions. My journey in technology has been driven by a commitment to problem-solving and continuous learning, allowing me to deliver high-quality, user-friendly applications that enhance user experience and streamline business operations.

Currently, I work as a Senior Software Engineer at Reaktor, where I design and code robust greenfield MVP solutions and improve existing codebases for clients. My expertise spans modern web technologies, including React.js, Node.js, and AWS, and I have a strong focus on creating responsive UIs and maintaining microservices. I thrive in collaborative environments, constantly communicating with key business stakeholders to ensure project success.

Throughout my career, I have also taken on roles that required backend development with PHP/Laravel and Node.js, as well as frontend development with React/Redux. I am always open to new challenges and side projects, as I believe in the importance of maintaining a diverse skill set and staying updated with industry trends.
