TD Cowen

Financial platforms demand more than clean UI, they demand reliability, speed, and trust. At TD COWEN, I took on the full stack: redesigning and engineering a mobile app from the ground up, building 20+ data-driven CRM features informed by real user behavior, and writing 40+ automated tests to make sure nothing slipped through the cracks. Daily adoption went up 40%, user engagement climbed 25%, and post-launch defects dropped by 30%.
