Full-Stack Software Engineer (Backend Focus)
📧 [open contact info ](look above in the "contact info" section) | 📞 [open contact info ](look above in the "contact info" section) | 📍 Ukraine | 🔗 Links: LinkedIn, GitHub
Summary
Full-Stack Software Engineer (Backend Focus) with 2+ years of experience in the modern stack, backed by 10+
years in ERP development (1с/BAS). Expert in SQL optimization, BigQuery, and ELT pipelines.
Focused on systemic engineering — balancing clean, maintainable code with pragmatic business delivery.
Contributed to an open-source analytics platform, specializing in building modular, high-quality products designed for
scalability and zero-downtime stability. Leverages deep understanding of business processes to translate
requirements into effective engineering solutions.
Currently completing an intensive Java backend course (GoIT) covering OOP, Collections, Multithreading, JDBC,
Hibernate, and Servlets. Transitioning to .NET — C# core maps directly from a Java background, and hands-on NestJS
experience (DI, modules, decorators, middleware) translates naturally to ASP.NET Core architecture. Strong SQL, data
modeling, and system design skills transfer platform-independently.
Looking for a Backend or Full-Stack role (Junior level) where I can apply my experience in building reliable
systems, solve complex data challenges, and continue growing professionally in a strong engineering environment.
