HexOust Board Game Implementation (4 Sprints) • Java, JavaFX
Jan 2025 | Apr 2025
  • Worked in a team of 3 developing and designing an interactive Java implementation of the board game ‘HexOust’ over the course of a semester.
  • Responsible for implementing the logic and rendering for the board of hexagons, using mathematics, geometry and JavaFX libraries.
  • Optimised the rendering of the scene to preserve consistency and implemented letterboxing such that the game can scale itself whilst maintaining functionality in order to ensure operation on varying screen resolutions.

Relationship of Time Complexity vs Energy Consumption • Java, Python
Jan 2025 | Apr 2025
  • Implemented a benchmarking application in Java to test the performance of various sorting algorithms (Treap Sort, PQSort, Collections Sort, Quick Sort, Merge Sort, Heap Sort) and the performance of data structures (Treap, AVL Tree, TreeMap).
  • Designed benchmarking methods that measure execution time and memory usage for each test, along with functions that generate different types of data to evaluate best, worst, and random cases.
  • Developed Python scripts for parsing energy consumption data from a hardware sensor logger, as well as for parsing, handling, and graphing benchmark results to visualize the outcomes.
  • Produced a detailed technical report analyzing energy-performance tradeoffs, providing critical insights into unexpected results.
  • Adapted to working on a large project as the sole contributor, despite the project being designated for a team of 4, demonstrating resilience and exceptional endurance in the process.

Interactive Gantt Chart with a Dependencies Feature • C
Mar 2023 | Apr 2023
  • Implemented a C program that allows a user to add tasks and dependencies of said tasks into an interactive gantt chart that can be modified at will and is displayed via the terminal.
  • Worked alongside a teammate and was able to designate specific tasks to each other as well as establishing a common ground for communications through the platform ‘Discord’.
  • Designed the print method responsible for rendering the gantt chart with ASCII and developed highly sophisticated methods of padding text such that the chart will adapt to the user’s demands.

Interests & Hobbies

Computer Hardware
  • Primary hobby! Love taking apart, repairing and building both PCs and Laptops. Actively purchase 2nd hand parts or laptops to either repair, upgrade or use. Keep up to date with latest hardware news in regards to CPUs, GPUs and other components.
Graphic Design
  • Extremely fascinated over the limits people can push when it comes to web design and graphic design. Occasionally mess around with Photoshop and After Effects to make animated GIF banners. Interested in Three.js for its 3D capabilities on the web.
Video Games
  • Enjoy gaming as a hobby but also fascinated over the more technical side such as datamining, modding and reverse engineering. Long-time competitive gamer (CSGO/CS2) and used to partake in LUA scripting but not too extensively. Interested in learning IDA and Ghidra some day.
