Experience
Programmer
Hello Games ltd
Core member of the engine team specializing in graphics and real-time rendering, leading the design and development of VFX systems
Contributing to and extended core rendering systems, including mesh rendering, lighting, shadows, texturing.
Proactively profiled and optimized rendering features and implemented features such as multicolour materials. Additional roles involve researching and experimenting new techniques, and developing internal tools, for example to visualise for wind direction and vertex density per pixel.
Delivered key graphics features such as Screen Space Shadows, Dynamic Wind for foliage, and mesh-based particle systems.
Graduate Render Programmer
Frontier Developments plc
ontributed to the engine rendering team
Working in fixing bugs, adding features, improving performance in the games researching new technologies and projects. Worked in common rendering techniques such as mesh renderers, shadows, lighting, textures, raytracing, anti-aliasing, motion blur etc. Work also on overall project maintenance which involves refactoring, profiling and restructure projects.
Workng with C++, lua. Working heavily with fragment, vertex and compute shaders, which are written in HLSL.
Google Summer of Code Intern
Liquid Galaxy Lab, The University of Lleida
Worked on the 3D Visualization API project an API for the creation of graphic scenes that can be integrated into Liquid Galaxy.
Liquid Galaxy is a view format allows third parties to easily apply common features in Computer Graphics directly to a Liquid Galaxyformat, a multi-screen display cluster launching instances of Chromium OS in each machine. This would include really commonly used properties in graphics, modelling a geometric object,applying lightning, animation, shaders and even textures.
During this timeDeveloped my technical skills and self organisation. In this internship I worked with Nodejs
Technology Summer Analyst
Morgan Stanley, London
Worked in the Derivatives Funding Margin Renovation team.
I was assigned a project about Environment Regression Improvement.
The aim of this project was to automate and allow the process of deploying to a different environment (in this internship the four environments were dev, qa, uat and prod) to be more scalable and beingable to run it end-to-end to test that there is no fixture needed in other environments and therefore avoid regression.
Developed my technical skills and team working. In this internship I worked in an Agileworkflow.
Web Tool Developer
STORM Team, IRIT, University of Toulouse
Worked with the STORM Team, a university Research team which focuses on computer graphics.
Developed a web tool based on the published paper in the University of Toulous, "Constrained Palette Space Exploration", and it was created using WebGL.
This project creates an automatic triad colour palette from a given colour thatthe user chooses. In this project there are two modes depending on how the other two coloursare found, geometrically or by numerical optimization.

Learning to control efficient 3D procedural noise from exemplars
September 2021
This work presents a proof of concept for the paper "Learning a Neural 3D Texture Space from 2D Exemplars" in which a model was presented to learn how to retrieve texture parameters from real-world texture pictures. In particular, this project includes designing a real-time rendering environment that can be used to generate an appropriate texture and to paint a shape with that texture. In addition, this project includes the optimisation of the original model presented in the aforementioned paper.

Information Processing in Medical Imaging
March 2020
Applying Machine Vision model techniques to analyse medical imaging. There are 2 parts of this project: Brain Tissue Segmentation, where I segment 2D brain images using a Gaussian Mixture Model and the Expectation-Maximisation algorithm; and Brain Tumours Segmentation using U-Nets, this includes loading data, designing U-Nets and evaluating performance

Maze VR game
December 2020
This is a asymmetric collaborative VR game were players. Two players start the game looking down at a maze on a table. One player can shrink down to enter said maze. However, this is no regular maze. The outside player must dynamically manipulate the maze in tandem with the inside player to help them traverse it. It is created with Unity.

Deep Learning for Image Synthesis and Denoising
December 2020
This project covers the evolution of image manipulation: starting with manual 1D/2D filtering, moving to supervised denoising with encoder-decoders, and concluding with stochastic generation using VAEs. Includes performance benchmarks between ADAM/SGD optimizers and perceptual loss tuning.

Constructive Solid Fluid Animation Simulation
March 2020
3D Water simulation, it simulates particles of water that flow in a cube, using javascript. The website allows the user to change the scene, so that it shows the simulation in different behaviours, like if the particles start all on top or if they are streaming. This is a GPU-based simulation using shaders.
-
Bubbles Simulation
December 2019
3D Bubbles simulation, it simulates bubbles in a drink inside a glass, such as in a soda or in a fizzy drink, using WebGL. The website allows the user to change some of the parameters of the simulation. This is a GPU-based simulation using shaders.
