BIONIC APE / UNREAL ENGINEERING
C++ & Unreal Engineering
Gameplay, plugins, multiplayer systems and difficult debugging.
Javier personally implements the demanding parts of games, simulations and real-time software. This work combines C++ development, Unreal Engine expertise, backend integration and technical ownership.
Selected engineering work.
Unreal Engine Premium Plugins
C++ tools and reusable components for Unreal projects, with interfaces intended for other developers to use and extend. Explore the plugin portfolio; the individual product pages describe each tool’s scope.
Dedicated server troubleshooting
A completed Upwork engagement focused on dedicated-server troubleshooting for an Unreal project. This is directly relevant to diagnosing the boundary between gameplay behavior, network state and the server environment.
Driving simulation performance
A completed Upwork engagement in Unreal Engine 5 performance tuning and level building for a driving simulator. The engineering focus brings scene complexity, runtime performance and the target experience into the same review.
geoJSON integration
A completed Unreal Engine integration engagement connecting geographic data to a real-time application. The work is listed in Javier’s public Upwork history.
From an unfamiliar project to a reproducible fix.
- Capture the engine version, plugins, build configuration and a protected baseline.
- Reproduce the broken workflow and trace the relevant C++ and Blueprint paths.
- Check object lifetime, asset references, initialization, network ownership and state changes.
- Repair a focused section, preserving working behavior and making the change reviewable.
- Verify in a packaged build and the required client/server setup; record remaining issues.
The systems around the game.
Interactive projects also need multiplayer services, data flow and operations. Hosting Suite covers game-server hosting and orchestration. For broader software architecture, integrations and applied AI, visit BACore.

A practical first engagement.
Start with a defined gameplay feature, a repeatable defect, a performance investigation or a small integration. Agree the target platform, test case and acceptance criteria, then review a working build and the source changes.
- Direct work with the engineer implementing the change.
- Short progress updates, with blockers and trade-offs made explicit.
- Source changes, setup notes and a repeatable verification path.
- Additional art, animation or specialist work scoped separately when the project requires it.
Work directly with the engineer.
Javier is based in Madrid and works with clients and small teams across software design, implementation, integration and delivery.
