About Mykhailo

Senior Unreal Engine Developer (UE5/UE4, C++) focused on building rock-solid gameplay and shipping on PC, PlayStation, and Xbox. I specialize in multiplayer, performance, and production reliability—turning design intent into fun, responsive, and maintainable systems.

What I do:

Architect core gameplay loops and features in C++ (with clean Blueprint exposure)

Multiplayer networking & replication (client/server, authority, prediction)

Gameplay Ability System (abilities, effects, cooldowns, tagging, PvE/PvP)

AI systems (Behavior Trees, EQS), animation integrations, and physics gameplay

Performance & optimization: CPU/GPU profiling, memory, async tasks, loading times

Online features: authentication/session, matchmaking, leaderboards, cloud saves, telemetry/crash reporting (Steam/EOS/platform services)

Console readiness: TRC/XR compliance, cert-friendly builds, hotfix pipelines

Tooling & pipelines: CI/CD, build automation, packaging, symbols, versioning

Code quality: reviews, refactors, testing, documentation, and mentoring

How I work:
I combine strong engineering discipline with a player-first mindset. Clear milestones, rapid prototypes, frequent playtests, and measurable performance targets keep projects predictable. I communicate risks early, provide options, and deliver production-ready code that teammates can extend with confidence.

Hire me if you need:

A senior UE engineer to own a feature from design to cert

A multiplayer specialist to bring up replicated gameplay fast

A performance pass to hit stable frame times on target hardware

A technical lead to level up code quality, pipelines, and team velocity

Let’s build something players will love.
