I hope you’ve enjoyed or are about to enjoy my portfolio. For the last 5 years I’ve been working in Unreal C++, but I love to work on new and exciting projects especially if I’m walking head first into the unknown. I’ve managed the look and feel of Wartorn with input and UI, refactored an old UI system with CommonUI, and built a dynamic camera AI. In the lands before I’ve even dabbled in Tech Design in UE3, animated a skeletal mesh for a game jam, and rebuilt a Deckbuilding Game I enjoy. As a teammate I find myself asking questions about the user experience. How can I contribute to an enjoyable game on Mouse and Keyboard or controller? Are we building a mechanic for today or architecting the system for tomorrow? I won’t hesitate to ask for feedback and confirm that what I’m working on will actually be to the benefit of the end user, the designers. I mean if they won’t use my sweet grappling hook, did I really even make it? Besides programming I love rock climbing, travel, and of course games. My favorite video games vary from League of Legends to Slay the Spire. I love all variations of strategy games. This love extends to boardgames where my favorite is Clank! Legacy. The genre of Deckbuilding adventure is incredibly addictive at merging strategy and chance to make a highly replayable experience. Slay the Spire kept me glued to the screen for weeks. Besides all of that I’ve been trying to keep up with reading Brandon Sanderson’s novels! https://www.jonathansarasua.me/resume daily 0.75 2025-08-05 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/daf25222-47f7-4e3a-bd96-66fdf192d082/Jonathan-Sarasua-Resume-20250801_UIGameplay.jpg Resume https://www.jonathansarasua.me/haberdashers daily 0.75 2021-03-05 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1612238635134-62KT6440YF0IFRNL4QNZ/KartOrientation.gif HaberDashers https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1612239699045-F99UEQON7ZO04LORQHOB/KartEffector.gif HaberDashers https://www.jonathansarasua.me/ludum-dare-46 daily 0.75 2023-05-18 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595109746475-Q83P0BJDN0UGT06EG8OF/lavaGolemShortenedV2.gif Ludum Dare 46 https://www.jonathansarasua.me/crystal-call daily 0.75 2021-03-14 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1612243505935-324Z448E3T0FXK46YQUB/ShootingIK.gif Crystal Call https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1611941862438-A786E9WE4PL0RGCVDNSF/WallRunning.gif Crystal Call https://www.jonathansarasua.me/chef-blob daily 0.75 2021-03-06 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595101981334-G6QAPEH4LDBNQN5H61HL/Whirlpool.gif Chef Blob https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595101953042-2WMOOB2G9V78YKUK9QBR/BlobAllNodesSelected.PNG Chef Blob https://www.jonathansarasua.me/bullet-hell-dungeon daily 0.75 2023-05-18 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595119476384-YFQC9PXGSYSQ9DFYBCFX/BDFight3Optimized.gif Bullet Hell Dungeon https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595131384990-QS33XKZYEXSPG1XV1OYO/WeaponsXML.PNG Bullet Hell Dungeon https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595114619228-749UGQ27R9NQ7VHPKC9Y/BDAnimations.gif Bullet Hell Dungeon https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1595131417535-OVMR0HL1CE6PEUF7G6F5/ActorsXML.PNG Bullet Hell Dungeon https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1614746199756-OWFCW94PWB35TPVVOHSA/Level1Map_V2.png Bullet Hell Dungeon https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1610737109746-49B2VC7GTB3J3YYOS45D/TileMap.PNG Bullet Hell Dungeon https://www.jonathansarasua.me/thesis daily 0.75 2023-05-18 https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616559398823-K92B5R6OGY5ZHDTN8M6L/InGameScreenShot.PNG Thesis https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616553033317-FIDCTNEOL32G9M7GVQOV/Dominion1_game_1050x700.jpg Thesis Dominion is a deckbuilding game of 2 to 4 players where each player takes turns playing and buying cards from a set of card piles Goal: Have the most victory points from victory (green) cards Game ends when: Province pile is empty OR three of any pile are empty In a 2 player game the victory card piles have 8 cards, the action cards have 10, and the treasure cards have their full deck (50+) https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616554309861-SW53S643D6BHC3MPS2P6/GoldAnnotated.jpg Thesis https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616554616187-ATY0X9HJWF3IWXO98PNP/ProvinceAnnotated.jpg Thesis https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616517363266-GSCJV99ZOQ45ZK2XJ9RE/VictoryCards.jpg Thesis - Anatomy of a turn: Play actions Buy cards End turn https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616517392164-M8NRCQBJTX6EW5ATGPOU/MarketAnnotated.jpg Thesis - Anatomy of a card Card Effect What you gain when you play the card Card Type Action, Victory, or Treasure Card Cost Cost to buy https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616556222816-LXDQIY9MOJIJIGJOY6YI/MCTSPhases.png Thesis https://images.squarespace-cdn.com/content/v1/5defd30e1d329522f68eec28/1616556795775-K880UY42ROQWST1XATHA/UCTFormula.PNG Thesis Score= Winrate, C theoretically equals Sqrt(2) UCT tries to balance going deep in the tree following highest score versus going wide in the tree following exploration value.
