About

Hiring a senior product designer for an AI or B2B SaaS product? I've spent 4 years owning design at LimeChat (YC W21), where 400+ D2C brands sell and support customers on WhatsApp. What that looks like in practice: • WhatsApp Commerce Suite: campaigns, support automation and chat checkout in one product. Merchant adoption up 29%. • Lime Design System: built from zero, with 100+ Figma components across 5 product surfaces. Dev handoff 20% faster. • AI agent UX: conversation flows, fallbacks, and the moment a bot hands a customer to a human, for our GPT-powered agent. I work with product, a 20-person engineering team and customer success, and I take research all the way to a shipped feature. I came in sideways. Architecture at NIT Raipur taught me to think in systems. Information Design at NID (AIR 1 in the entrance) taught me to make complicated things readable. You'll see both in how I break down a messy flow. I'm looking at Senior Product Designer roles in AI-first and SaaS companies.
