I'm Javi, a Senior UX Designer, Career Lead & Mentor based in Santiago, Chile. Most recently I led UX features for Apex Legends at Electronic Arts, owning HUD design, accessibility systems, and player-feedback loops for a global competitive audience. Before that, I was at Epic Games on Fortnite Creative & UEFN, shaping the tools that let hundreds of millions of players build their own worlds. I don't just design, I bridge UX, engineering, and game design to make sure the right thing ships, not just the prettiest one.
Beyond gaming, I've shipped across aviation, healthcare, logistics, and government, always at the intersection of scale, complexity, and real human stakes. I hold a Master in Advanced Design and, unusually for a designer, a degree in Clinical Psychology, which shapes how I approach research, team culture, and the humans on the other side of every screen.

Vantage was underperforming in fights and seeing less play overall. As a sniper, her role grows more difficult as the game progresses and the playspace shrinks. The goal was to keep her kit powerful at every stage of the game through clearer UX communication and a redesigned HUD.
Scope
Vantage — Legend Locker (Recon · Survivalist Sniper)
Vantage — upgrades tree (LVL 1–3)
The Challenge
Vantage was underperforming because her kit's complexity wasn't communicating clearly to players. Canted Sights — a side-mounted 2× alternate sight toggled via the weapon fire-mode button — was being confused with the ADS system. Ult Charge, gained through Spotter's Scope pings, had no clear visual link between the spotter mark and the bullet UI charge.
The design challenge: communicate these mechanics clearly without overloading the HUD, and ensure every feedback loop felt intentional and readable mid-fight.

Fuse's ultimate was seen as too difficult to use and often unimpactful. The rework focused on making it easier to find effective use cases while cementing Fuse's identity as mobile artillery — clearing large spaces and tagging enemies with a quicker, more responsive kit.
Scope
Fuse — Legend Locker (Assault · Explosives Enthusiast)
Fuse — upgrades tree (LVL 1–3)
The Challenge
Fuse's ultimate was seen as too difficult to use and often unimpactful. The design goal was to refocus the ult on clearing large spaces while making the tactical quicker and easier to use for tagging enemies. The reduced duration on Knuckle Cluster also helps players follow up on their own damage — particularly alongside his passive change.
Knuckle Jumper replaces Knuckle Hustler as a movement option — more "Fuse-y," with plenty of nuance to master across its many use cases.

Before & After

Redesigned the game lobby and matchmaking system to unify the experience across Battle Royale and Creative modes — reducing confusion for millions of concurrent players worldwide.
Key Decisions
The Challenge
Fortnite hosts radically different game modes — Battle Royale, Creative, and others — yet matchmaking and game details pages had grown inconsistently, with different layouts and hierarchies depending on which mode a player entered.
The goal: design a flow that felt custom-created for each mode, yet cohesive within the broader Fortnite ecosystem — balancing engineering feasibility, UX clarity, and the existing Tech UI system.

Design Decisions
Designed a new spectator camera system for Fortnite Creative, giving island hosts the ability to broadcast gameplay with three distinct camera modes for custom events and tournaments.
Key Decisions
Spectate camera mode selector
Context
The existing Spectate mode — shared with Battle Royale — only let players cycle through other players. Battle Royale's spectate UI had a recent visual refresh, but no new functionality. The Creative team had a clear ask: give spectators camera view control.
Creative is fundamentally different from Battle Royale. Spectators aren't watching a competitive match — they're observing collaborative builds and player-made games that need entirely different camera perspectives.
Feature Scope
Camera view controls — KB/M, Controller & Third Person
The Solution

Design Challenges
Outcomes
Enabled players to freely reposition the in-game text chat window across the HUD — a meaningful accessibility improvement for Fortnite Creative mode players on all supported platforms.
Key Decisions
Text chat window repositioning in-game
The Opportunity
Fortnite's new text chat was a significant launch. For the first time, players could communicate during gameplay and in the lobby without voice chat — a meaningful accessibility improvement for players with hearing disabilities.
But the initial release came with a limitation: the chat window was fixed in position. In Creative mode, where HUD layouts vary enormously, this quickly became a pain point.
Community feedback that drove the feature
Design Scope
Design Constraints
Chat repositioned — center placement
Chat repositioned — bottom right placement
HUD Safe Zones
Rather than free-position anywhere, the design defined anchor zones — areas of the HUD consistently free from critical game UI — where players snap the chat window.
