About Me

I’m a Senior Product Designer focused on building high-clarity product experiences, scalable design systems, and 0→1 workflows for complex digital products.

Currently at Perccent, I work across consumer fintech, onboarding UX, interaction design, design systems, and brand foundations. Previously, I worked at Odessa on enterprise workflow design and product interaction systems.

My work sits at the intersection of:

  • Product design and conversion-focused UX
  • Design systems and design-to-engineering workflows
  • Fintech, SaaS, and operational platforms
  • Rapid prototyping, validation, and interaction modeling

Key Impact

  • Contributed to a 27% reduction in UI defects through a scalable Figma-to-React design system
  • Built and scaled product experience systems used across 4 product squads and 12+ engineers
  • Helped grow Hack4Bengal into a 7,500+ member developer community
  • Designed digital ecosystems supporting 15,000+ monthly visits during peak hackathon cycles
  • Reduced UI engineering rework and enterprise time-on-task by 20% during my time at Odessa
  • Won 1st Place in Global Launchpad Innovation out of 63 teams

Current Focus

  • Consumer fintech UX
  • Onboarding and activation flows
