What I'm looking for

I am looking for a role that fosters innovation and collaboration, with opportunities for growth and learning.

I am a Senior Software Engineer with a Bachelor's degree in Computer Science and a focus on client needs. My journey in software development began in Saint Petersburg, Russia, and has led me to Barcelona, where I currently work at Wallapop. I thrive on designing and developing high-load, scalable systems, always aiming to deliver robust and high-quality solutions.

At Wallapop, I have successfully developed new integrations with various payment systems and built a centralized API that enhances the flexibility of product item displays. My work has significantly improved product discovery capabilities through innovative frameworks that enable parallel querying of multiple search engines. Prior to this, I led a team at Holaluz, where I organized the development of a documentation generation system for solar panel installations and mentored teammates to enhance their technical skills.

With a diverse tech stack that includes Kotlin, Java, PHP, and various cloud technologies, I am committed to continuous learning and adapting to new challenges. I believe in the power of collaboration and strive to create solutions that not only meet client needs but also push the boundaries of technology.
