I worked directly with the researchers at Pasteur throughout the process — sitting with them, watching how they worked, understanding what slowed them down and what they actually needed from a tool like this. The requests were specific: faster batch uploads, smarter ways to flag when the AI missed a plaque, multi-select for similar values, customizable formulas for results calculation, and collaboration across different user roles. Every one of those made it into the product. Prototypes were tested and validated with the team, iterated until the interface felt as natural as the workflow it was replacing.
