Field report

Aparici needed a B2B service that could make a deep premium-product catalog useful without allowing its size to compromise the experience.

I built across the React front end and Python back end, translating product and commercial requirements into a maintainable, high-load application.

The project is a good example of the thread running through my engineering and DevRel work: complex systems become valuable when their structure is made clear to the people using them.
