Boldizsar Akos Mezei
Verified Expert in Engineering
Team Lead and Full-stack Developer
Boldizsar is a Java/Scala back-end developer who has worked at Morgan Stanley on a group of microservices. His primary focus is backend development but he is also open for Android development. Boldizsar considers himself a hybrid in the sense that he is highly business-focused. When dealing with tasks, he would rather choose the inconvenient, unusual way to achieve the best outcome both for the client and the project itself.

Work Experience
Team Lead and Full-stack Developer
NXT Mortgage
- Worked as a full-stack developer and tech and team lead.
- Oversaw the complete development lifecycle of the project that relied entirely on a Cloud infrastructure.
- Created CI/CD pipelines that highly increased team productivity.
Java/Scala Developer
Morgan Stanley
- Upgraded a group of microservices to use a more efficient way of serializing and sending data through the web—transferring the same amount of information in a 50% smaller size reduced the execution time and running costs for the firm.
- Collaborated with peers worldwide (India, London, New York) to upgrade a legacy Java system to use the most up-to-date Java, Gradle, and Spring versions.
- Created an API for an immense Scala-based back-end project. This allowed several upstream services to communicate directly with this component, thus allowing the smoothest flow for a million dollars worth of transactions.
- Onboarded Agile methodologies that increased developer productivity by 30% and reduced time to market by 20%.
- Mentored several new team members and junior software developers, both personally and professionally.

http://raha.fi/lainat/lainojen-yhdistaminen/Client testimonial: "I can highly recommend Boldizsar for demanding software development jobs. Boldizsar cares about his work and you can really see it through his communication and professionalism. He managed to grasp our business context and application very quickly and fixed messy code written by the previous developer. Boldizsar delivered tasks always on time and most important were pro-actively fixing issues or suggesting improvements."
Parseports
In the beginning, I was the back-end developer for this project. As the project grew and we hired more developers, I became a full-stack developer and tech/team lead. My role was to oversee the complete development lifecycle of the project, add and upgrade new features on the back-and-front-end site, and organize tasks among team members.
PHirst App
Initially, I was the back-end developer for this app. My role was to provide a stable and highly scalable back-end service for the iOS/Android-based front end. Soon, as the project grew, I took the initiative and became the tech/team lead and full-stack developer. After that, my job became more complicated as I had to manage the team and be responsible for the Android front end.
