Mana Force (Video Game)
Mana Force is a top-down 3D action game where the objective is to use the boss's abilities against them. I was one of the two gameplay developers and game designers in a team of three people.

For this project, we had to put an event-driven architecture in place to handle the game logic and the interactions between many individual game entities, which allowed us to compose very complex entities while keeping the inter-component dependencies very low. This, in turn, improved maintainability and allowed us to add new game features at a great pace.

Beat Beat Shooter (Video Game)
A 2D sidescrolling rhythm shooter, the game combines the classic controls and objectives of a regular 2D shooter where you move your ship and shoot the enemies while traversing the level, but it comes with a twist: in order to get more powerful, you need to keep the beat of the music.

For this project, I took on two roles: programmer and artist. The programming side hard interesting challenges, to name a few:

• Implementing a palette system and shader where we could reuse the same visual assets but apply different color palettes to them, depending on how well the player was doing.

• Read music audio files and analyze the BPM (Beats Per Minute) of the song to make several gameplay elements sync with the beat of the music.

A PHP-based web app that allows people to search a database of items for the game Dota 2. Some functionality includes visualization of the Steam market and Dota 2 store prices and statistics, search and filter items by Dota 2 heroes and categories, and search inventories.

I was one of the two developers involved in the application's back and front end during its initial development up until launch.

Trinity Archetype
Trinity Archetype is a roguelike, turn-based RPG made in Unity.

Analyze upcoming actions and plan your own. Use the unique Skill Boost and Party Inspire mechanics to get the upper hand in battle.

Start your journey as the three warriors chosen by the ancient archetypes and get rid of the corrupted threats unleashed in your world.
