Transit Data Visualization Specialist

Ryan Mahoney

Director of Product, FirstWho

“It is really hard to find someone who builds interactive dashboards and actually listens to the operations team. Most candidates care more about how things look than whether the real-time data feed is accurate or reliable. We need people who take charge of their work without asking for permission on every technical decision about libraries. The hard part is telling the difference between a shiny portfolio project and a tool that holds up under daily pressure. The best hires check their work against real results for the agency instead of just shipping code that looks good.”
