About
I’m interested in understanding how a product works beyond its interface: how data is validated, how responsibilities are organised and how consistency is maintained across the system.
I’m currently completing the IFCD0112 professional certificate and building practical projects involving frontend, backend, databases, testing, Docker and CI/CD. My previous professional experience has also given me a strong foundation in organisation, customer service, coordination and day-to-day operations.
