ArkZ is a top-down tactical shooter where the player leads a team of marines to survive and explore an aircraft carrier where an infection turns humans into monsters. I implemented the prototype and later coordinated the project's production, while actively collaborating in the development.

As a software developer on a physics-based racing game, I was tasked with refining the existing codebase to introduce new gameplay features and improve player mobility. I worked closely with the art team and the creative director to align technical enhancements with the game's visual and conceptual goals.

The main challenge was to integrate these new features and resolve existing bugs without compromising the game's well-regarded physics system. By carefully adjusting and extending the game mechanics, I managed to maintain the realistic yet flexible physics that fans appreciated.

Adaptive Cognitive Evaluation Explorer (ACE-X) is an adaptive mobile assessment tool with 15 tasks to measure multiple aspects of the human brain's executive function. This app belongs to Neuroscape, the neuroscience center of the University of California San Francisco.

As the new developer in charge, Oliver migrated the original prototype from Objective-C to Unity in a couple of months. Since Neuroscape initially expected the development time and costs to be way higher, they decided to use their remaining budget to extend the project's scope, including new features, tasks, and UI.

The biggest challenge was to display and capture precise and normalized data across several devices. The researchers would then use this data to support scientific research that would be pair-tested.

The initial prototype that I developed for a 3rd-person adventure game to aid children with learning difficulties, particularly dyslexia. In close collaboration with the game director, my role encompassed prototyping game mechanics, contributing to the game design document (GDD), and refining the UI/UX. Additionally, I was responsible for the game's tech art, focusing on creating a visual style that supports our educational goals.

The project's success was marked by delivering a functional prototype that offered the client a concrete product vision.

One of the views that I developed for an advanced smile design application for dental professionals combining React and Three.js to craft a web view with several tools for mesh rendering, deformation, and manipulation.

This project involved close collaboration with the product owner and team. I applied modular design and high-quality code through adherence to SOLID principles and the React framework. Key challenges included optimizing real-time rendering for complex models with hundreds of thousands of vertices and devising unique algorithms for precise mesh deformation and manipulation.

To overcome these challenges, I engineered optimized versions of mesh deformation algorithms, custom visualization shaders for medical visualization, and a dedicated server for the intensive mesh processing tasks that can be offloaded.

This project was a metaverse experience for employees from a multinational company. I led a multidisciplinary team of 15 developers and engineered critical parts of the architecture.

The platform needed to support thousands of concurrent users distributed among rooms with up to 100 users per room. There was also a concert-like room where 1-5 particular users could broadcast to an audience of more than two thousand spectators—the experience needed to support VR and PC interfaces.

I designed the system's architecture, including game servers, load balancing, logic servers, and databases. I also implemented and optimized the replication of the actors in the rooms and implemented the core features of the multiplayer VR.

A 3D, social multiplayer Web3 game project similar to Fall Guys, a free, cross-platform massively multiplayer party royale game. I was hired as one of the lead web developers during the early stages of development from 2021 – 2022.

My expertise in web architecture was essential in setting up the project with Next.js, and I also implemented some of the UI interactions. My graphics programming skills also proved valuable to the team, as I helped with shaders and optimizations for Three.js.

A construction company asked me to build a prototype to visualize apartments and offices in virtual reality.

This project took three weeks, and the end result was a VR simulation using the HTC Vive headset, where users can change the structure's materials and add furniture.

My job was to program the interactivity, compose the scene, specifically lighting and post-process, and direct artists during the generation of the required assets.

Locos por las Canchas (LpC) was a platform to book soccer courts and build teams in South America.

I designed and implemented the native iOS and Android apps. I used Mixpanel, Oliver, and LpC's founders studied the analytics data and ran A/B testing. This maximized up to 300% user conversion over four months.

With systems in place to track and catch errors, the apps failed in less than 2% of the clients after launch. I pinpointed and quickly fixed the errors, and crashes, then tracked incompatible device models and removed them.

The company aimed to create a platform allowing fans to follow their favorite athletes and teams using AI and data science to aggregate news and social media content from the internet. I quickly adopted the team's implementation of React+Redux, created new page components, and fixed bugs, making significant contributions to the platform's development.

The team found his broad skills and expertise so valuable that they asked me to help with styling, analytics, and data analysis, which he tackled efficiently and effectively.
