Independent senior software engineer · Novi Sad, Serbia
Senior engineering for complex software systems.
I work with software companies and engineering teams on complex backend development, cloud infrastructure, integrations and AI-powered applications.
With 9+ years in software engineering, I can join an existing project, investigate difficult technical problems, make architectural decisions and take responsibility for implementation.

01Where I fit into a team
Senior engineering capacity for work that needs ownership.
I work with founders, CTOs and engineering teams that need experienced hands-on capacity or someone to take ownership of a difficult technical workstream.
I can join an existing codebase, investigate unfamiliar systems, make architectural decisions and implement changes through to production. Engagements can be ongoing with reserved weekly capacity or structured around a defined project.

About Serhii and professional experience ↗04Ways to work together
Defined engineering project
A specific implementation, integration, migration or technical improvement with agreed deliverables, milestones and responsibilities.
05Continuity without lock-in
Direct responsibility, with your team in control.
Source code normally lives in a client-controlled repository. Important decisions, deployment instructions and recovery paths stay documented so another engineer can understand and operate the system.

Let’s discuss the engineering work.
If you need help with an existing system, a difficult technical problem or a defined implementation, send me a short description. A formal specification is not necessary.
