I'm Javi, a Senior UX Designer, Career Lead and Mentor based in Santiago, Chile. Most recently I led UX features for Apex Legends at Electronic Arts, owning HUD design, gameplay features, and player-feedback loops for a global competitive audience. Before that, I was at Epic Games on Fortnite Creative and UEFN, shaping the tools that let millions of players build their own worlds. I don't just design, I bridge UX, art, engineering, and game design to optimize product impact.
Beyond gaming, I've worked across aviation, healthcare, eCommerce, logistics, and government, always at the intersection of scale, complexity, and real human stakes. I hold a Master in Advanced Design and a degree in Clinical Psychology, which shapes how I approach research, team culture, human interaction and perception for every experience I create.
Senior UX Designer
Eight years across gaming, aviation, healthcare, eCommerce and logistics. Most recently shipping live-service features at Epic Games and Electronic Arts for titles like Fortnite and APEX Legends.
Selected Work · 2022 — 2026
I am the feature owner of the Legend Meta changes at Apex Legends, meaning I do all the XD gameplay related tasks for every release for the past 1.5 years. I've worked on the updates of over 23 characters.
I work hand in hand with game design, VFX, SFX, animation, hard surface, UI art and Tech UI teams to ensure the quality of every implementation. As the Lead UX I monitor and follow up every stage end to end, playtesting all our features 3 times a week internally and externally before shipping.
This is a brief selection of some of the work I've done so far for Vantage and Fuse.
Context
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's kit was underperforming in clarity and player feedback, leaving her abilities hard to read mid-fight and her ADS zoom insufficient for mid-range combat. To address this, we introduced a new 2x fire mode and extended her scope from 3x to 4x, giving players a broader range of sight options and making her a more versatile pick across the battlefield.
We also extended her Passive with a new mechanic: Pinging (Spotters Lens) an enemy beyond 50m now charges her Ultimate, rewarding map awareness and reinforcing her identity as a long-range specialist.

Key improvements
Official release
Released in Season 29 (May 5 2026), the Vantage rework was immediately recognized across the community as one of the season's strongest upgrades, repositioning her from a niche pick to a competitive Recon threat. Early data shows a 52.1% win rate and a 2.3% pick rate, with top tier lists moving her into A/S tier for the first time since her release.
Community
Context
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 impactful in concept but difficult to execute, with a UI that didn't give players enough clarity to deploy it confidently. The rework rebuilt it from the ground up: same name, but now fires a projectile that explodes on landing and sprays 16 outward explosives with a 2-second fuse, dealing up to 30 damage each. A new right-click breach mode lets players punch through cover and detonate on the other side. A redesigned icon and updated UI clearly communicate when breach mode is active, removing the ambiguity that held the ability back.

Key improvements
Official release
The Fuse rework shipped in Season 28 and immediately repositioned him from a niche pick into one of the strongest Assault legends in the meta. His pick rate climbed from under 1% to 4.2%, with community tier lists placing him in S tier for the first time. His reworked Motherlode and new Knuckle Jumper upgrade validated the core design direction and made him the defining pick of the Breach meta.
Community
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.

Iterations



The redesigned flow gives players clear, real-time feedback across every phase, time in queue, server status, updates, and required downloads, culminating in a distinct moment when the island is found.

Final Results
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

Current spectate mode
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.

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 release
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
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.
