Maxym Perebyinis
BACKEND .NET DEVELOPER
Backend .NET developer with 2.5 years of commercial experience
working on a large ERP system. I build both new modules and the
integrations that connect it to other systems (REST, SOAP,
DBLink), backed by SQL across Oracle, MSSQL, and PostgreSQL.
My main domains are government and accounting, and I work
directly with clients to define requirements. Comfortable bridging
legacy and modern stacks. Currently pursuing a Master's in
Software Engineering at KPI.
