Senior Backend Engineer, Automotive MediaVentions
May, 2024 - Present
Backend developer on Automotive platform
As a Senior Scala Engineer at BUX, I apply my passion for functional programming and distributed systems to build scalable and reliable backend services for the online trading platform.
I have over 10 years of experience in software development, with a strong focus on Scala and JVM technologies.
I have successfully led and contributed to multiple projects involving microservices, REST API, Kafka, Akka, cats, cats-effect and http4s. I also have proficiency in Python, Kotlin, Rust, Google Cloud Platform and various databases.
I hold a master's degree in Mathematics and Informatics from Kherson State University, where I developed my analytical and problem-solving skills.
I enjoy learning new tools and frameworks, collaborating with other engineers, and delivering high-quality code that meets the business needs and user expectations.
