Hello there!

I’m a software engineering student working at an applied R&D consultancy, building simulation tools, data pipelines, and full-stack systems for industrial and defence clients. I’m particularly interested in distributed systems and low-level performance engineering.

Current Employer

Lead Software Engineer

Working at an applied R&D engineering consultancy working with industrial and defence clients, across simulation, data processing, and full-stack systems, contributing to both system design and implementation.

Tasks include:

Leading teams and developing production software for client-facing engineering tools
Contributing to system design, technical decisions, and project delivery
Working directly with clients to translate requirements into technical solutions

mWork Deliverablesn

Advanced Ground-to-Ground RF Propagator

Developed a Python-based RF propagation simulator modelling ground-to-ground transmission over terrain.
Implemented elevation profiling, atmospheric attenuation, and ITU/IEEE loss models to simulate real-world signal behaviour. Automated SNR calculations across transmitter/receiver pairs, reducing reliance on manual field testing for network planning.

mqn

Health Infrastructure Asset Bidding Assistant

Built a full-stack application (Python, SvelteKit) for healthcare infrastructure planning.
Implemented calculations derived from Australian Standards (AS) and AusHFG datasets to predict 140+ building service assets per facility. Replaced spreadsheet-based workflows, improving consistency and reducing estimation error in planning processes.

APersonal ProjectsB

3D Voxel Engine | Java, OpenGL

Built a multi-threaded voxel engine in Legacy Java (Java 1.6, LWJGL 2.9.3), doubling frame rate via parallel mesh generation, lock-free data structures, and low-level optimisations. Implementing GPU-driven rendering with compute shader culling to eliminate CPU bottlenecks.

Portfolio | Sveltekit, TS/JS, Tailwind

Seanparkinson.net

Built a full-stack personal website using SvelteKit and Cloudflare Workers for edge delivery. Used to document projects and technical work, focusing on performance, simplicity, and fast global load times.

TeamTrack | .NET, React, SQL Server

Developing a full-stack time tracking system with role-based access control, supporting time logs, breaks, and project-level reporting. Designed REST APIs and relational schema, with a backend-first architecture targeting a deployable MVP.
