Summary

Systems-oriented Product Designer with 4+ years shipping complex B2B SaaS products across 6+ industries. I design configuration-driven frameworks and modular systems — not just screens. I prototype in code (Next.js, TypeScript, React), use AI tools as creative partners in my daily workflow, and operate at the intersection of product strategy, system design, and polished UI. I've shipped in fast-moving, resource-constrained environments where ambiguity is the default.

India

  • Designed AuthEngine — a configuration-driven login framework with a modular object model (Login Module, Auth Method, Reference Variable). Reduced per-client login setup from 7 days to minutes, eliminating engineering dependency for standard enterprise onboarding.
  • Architected an AI-readable design system from scratch — structured tokens, naming conventions, and component APIs so both engineers and AI coding tools (Claude Code, Cursor) produce consistent, shippable UI without manual oversight.
  • Vibe-code production prototypes in Next.js/TypeScript to validate system-level design decisions before engineering handoff — including interactive case study components, state-flow visualizers, and config previews.
  • Orchestrated seamless integration across 6+ cross-industry platforms (banking, insurance, automotive, hospitality), designing customizable, native-feeling UX that reduced client-side integration effort and boosted adoption.
  • Guided product direction and go-to-market strategy in direct partnership with founders, PMs, and engineering leads — encompassing stakeholder reviews, sprint planning, and design handoffs.
  • Elevated app UX, boosting user task completion rate by ~28% through targeted usability enhancements.
  • Use Claude Code, Cursor, and AI-powered Figma plugins as core parts of the design process — from rapid prototyping to A/B test analysis — reducing design feedback loops by 50%.

What's Next

I design at the intersection of AI and product — where systems thinking meets craft. I'm looking for roles where I can shape how people experience AI tools, prototype ideas in code, and ship fast in high-ambiguity environments. Interested in developer tools, AI products, and teams that treat design as a strategic function, not a service layer.
