SUMMIT OF ELEMENTS
Game UI/UX & Design Systems- Architected the foundational UI design system and graphic style guide for an elemental farming RPG, defining color theory rules, pixel typography standards, and scalable component hierarchies.
- Designed the master multi-tiered inventory and status hub featuring a 30-slot storage matrix, 5-slot equipment bar, contextual info panels, and tabbed navigation, optimizing layout readability across complex game states.
- Led an iterative UX pipeline across 3 milestone stages, conducting comparative value and contrast studies against commercial benchmarks to calibrate screen overlays and ensure a good visual hierarchy.
- Authored a comprehensive UI/UX Design Guidelines Document establishing production-ready standards for downstream feature development.
"Working with Sofi was an amazing experience. She took an inconsistent collection of UI and turned it into a cohesive visual style that genuinely feels like part of the game.Communication was excellent throughout. Instead of jumping straight to finished designs, we started with rough mockups, discussed different directions, and gradually refined everything through feedback and revisions. It made the process feel genuinely collaborative and allowed us to slowly build towards the right UI rather than trying to get everything perfect immediately.
She also thought beyond just making things look good, considering readability, hierarchy, spacing, and how everything would actually work in-game. The final delivery and style guide were well organized and have made it much easier for me to continue building UI while keeping everything consistent.I'm extremely happy with the result and would absolutely recommend Sofi to other game developers."- Ferre, Indie Dev Working On Summit Of Elements

- Designed 6 core interactive screens and 2 adaptive layout variations—including a dense 65-node HUD, an expandable recipe codex, and non-linear strategic upgrade trees—maintaining cohesive visual hierarchy across dynamic game states.
- Engineered a zero-friction developer handoff by defining explicit technical asset specifications (atlas packing rules, slicing margins, resolution bounds), resulting in zero integration bottlenecks, rework requests, or engine-level implementation errors.
"I had an incredible experience working with Sofia.
I hired her to work on art assets for my cooking themed tower defense game and ended up expanding my commission to a huge portion of the games art and design.
She was accommodating and professional and had an excellent skill at combining her own creativity with my vision.From my perspective as an amateur developer, she was extremely easy to work with and incredibly talented."- Alex, Indie Developer of Feed Everyone
