A C++ application that loads geographic data, renders the map environment (streets, intersections, points of interest), and supports interactive exploration and route-oriented behaviour. The emphasis is on correct structure for spatial queries and responsive navigation under realistic data sizes.

My contributions: Led map rendering implementation for roads, intersections, and POIs; developed and optimized path-finding algorithms for route queries; implemented delivery routing logic for multi-stop courier-style tasks; and improved performance by refining spatial data access patterns and profiling bottlenecks during team integration.

Technologies: C++, custom data structures, geographic/map processing, team Git workflow.

A 2D shooting game implemented in Verilog on the DE1-SoC platform, with VGA output and keyboard-driven control. Game behaviour is organized into modular finite-state machines for the player, enemies, and projectiles so timing and state transitions stay maintainable.

My contributions: Designed modular FSM architecture for player, enemy, and projectile control; implemented VGA timing and rendering pipeline for stable frame output; integrated PS/2 keyboard input and debounced control flow; organized sprite/background asset storage with MIF initialization; and iterated through simulation and on-board debugging to fix timing and state-transition issues.

Technologies: Verilog, Intel DE1-SoC, VGA, PS/2, MIF, Quartus toolchain.

A C program that models patient triage and queue behaviour using a dynamic singly linked list, illustrating priority-aware queueing and careful dynamic memory use in a resource-sensitive setting.

My contributions: Implemented the triage queue with a dynamic linked-list structure and priority-aware insertion logic; designed modular memory allocation/free routines for predictable behavior; added robust edge-case handling for empty lists, repeated updates, and removals; and validated correctness with targeted test scenarios for queue ordering and lifecycle safety.

Technologies: C, dynamic memory, linked lists.

A prototype vision pipeline concept that relates food appearance in images to weight estimates via surface-area style cues, exploring how calibration and geometry-aware processing could support a practical measurement aid.

My contributions: Defined the end-to-end pipeline from image capture to estimation output; experimented with contour extraction and geometric feature engineering for area-based cues; prototyped calibration workflows linking pixel-domain features to physical weight estimates; and evaluated error sources such as perspective distortion, lighting variation, and container boundary noise.

Technologies: Python, OpenCV concepts (contours, calibration).

An early design-course project proposing a conceptual redevelopment of the Bahen Centre courtyard at U of T, combining stakeholder input, environmental considerations, and student-focused usability goals.

My contributions: Conducted stakeholder and user-needs analysis with structured requirement capture; contributed to environmental and site-constraint assessments; translated findings into design alternatives balancing accessibility, sustainability, and daily campus usage; and helped consolidate the final proposal narrative, rationale, and team presentation materials.

Technologies / methods: Engineering design process, written proposal, teamwork.
