Security Administration
I am currently a Flutter Developer at Racenext, where I’ve spent
Flutter
the past 2 years building cross-platform mobile applications with
clean architecture, efficient state management, and a strong focus
Languages
on performance and user experience. I enjoy transforming business

requirements into scalable, high-quality mobile solutions and

Certifications
NTA-Pb Python: programming from
scratch Before transitioning into mobile development, I built a solid 12+
year foundation in IT as a System Administrator at YEDNIST'
GROUP. There, I implemented and maintained software systems,
ensured infrastructure stability, and protected the organization’s IT
environment. My NTA-Pb Python certification further strengthened
my technical versatility and ability to automate workflows and
develop custom solutions.

Earlier in my career, I served as a Senior System Administrator
at Ukrposhta and Nova Poshta - two of Ukraine’s largest postal
service companies. I managed large-scale infrastructures and data
center operations, resolved complex technical issues, supported
servers and networks, and ensured high system availability. I also
coached junior team members, helping them grow their technical and
operational skills.

Combining my background in infrastructure with hands-on mobile
development, I bring a unique perspective to building reliable,
scalable, and user-centric digital products. I value teamwork, clear
communication, and continuous learning, and I strive to deliver
excellence in every project I take on.
