> Senior Software Engineer @ Bloomberg | Leveraging TypeScript, Java & Python to build Scalable Financial Systems

Location: Princeton, New Jersey, United States
Profile: https://flows.cv/yevhenii

I build reliable, scalable systems that power financial tools used around the world. At Bloomberg in Princeton, I work with TypeScript, Python, and Java to solve complex problems with speed and clarity.

My background in QA Automation helps me write clean, maintainable code and catch issues early—before they impact users. I bring both a developer’s mindset and a strong focus on quality.

Over the years, I’ve contributed to engineering teams at Wix.com, Luxoft, and EPAM Systems. Some highlights from my work include:

Developing internal tools that improved developer workflows and reduced manual testing time by 40%

Building a Java-based test framework with over 90% regression coverage, speeding up release cycles

Redesigning parts of an automation platform to cut maintenance time by 20%

Increasing test coverage by 40% across frontend and backend systems

What I enjoy most is solving real-world problems with code—whether it’s improving performance, streamlining development, or building tools that help teams move faster.

Outside of work, I stay curious. I enjoy exploring new technologies and keeping up with trends in software engineering. For me, great software comes from collaboration, continuous learning, and staying close to the problem.
