My role at Littlepay was to perform L3 device integrations on cEMV readers for use in mass transit solutions. Over my time spent there I tested these devices to ensure they met the criteria set by acquiring banks and card schemes and would advise our partners and technical teams on any remedial actions needed to fix failed tests. I would also monitor transaction volumes and statistics through AWS and report on any issues or fraudulent transactions. I was also part of the winning team for an internal company hackathon sponsored by Amazon.
