Alex Fullerton
Software engineer with a background in Engineering Physics.
I build production software where engineering and science meet, owning releases end to end and turning complex requirements into solutions people can trust.
Projects that show range
Production SaaS, autonomy software, and scientific instrumentation — three slices of how I work.

Infection Prevention Compliance SaaS
Led product and full-stack development of a multi-tenant healthcare SaaS for infection-prevention and regulatory compliance workflows (Vue 3, Express/TypeScript, Prisma, MariaDB). Launched major features end-to-end including new database models, REST APIs, and migrations, while strengthening multi-tenant access controls and RBAC; contributed to an OpenAI RAG assistant over tenant knowledge libraries; owned weekly production deployments and code review for a 3-engineer team.

Queen's Autodrive — Behaviour Planner
Designed a behaviour planner in MATLAB Stateflow to drive an autonomous vehicle from map and perception inputs. Used MATLAB Coder to auto-generate C++ and verified the generated code against the Stateflow reference via SIL/PIL, plus RoadRunner simulation scenarios. Integrated planner behaviour with shared Autonomy Team interfaces in Git and presented verification progress at Autodrive executive design reviews.

Ku-Band Radio Telescope
Led Python software for dual-axis stepper control over a serial interface, celestial pointing, and SDR sensor acquisition for a Ku-band radio telescope. Added command validation to reject unsafe zero/fractional motor steps; integrated motor control with intensity/PSD pipelines to build sky heat maps. Built OOP control software to track motor pose, pointing angles, and radiation readings for multi-hour unattended operation.

A bit more context
When I’m not shipping software, I’m usually training for triathlon, climbing, or reading. Those habits keep the same curiosity and diligence that shows up in my engineering work.
