About
Product designer with 8 years of experience shaping complex systems. From agentic AI workflows to infra tools to fintech at scale. Currently leading design at SciSpace, defining the experience layer for AI-powered research tools. Background in physics; still solving complex problems, just with better aesthetics.
Designed the zero-to-one agent experience for SciSpace — unified PaperTable, Deep Review, and Insight generation into a coherent agentic layer; ARR doubled within 7 months of launch.
Built the SciSpace Design System from scratch; accelerated design-to-dev cycles and established scalable component foundations for the agent interface.
Defined Human-in-the-Loop interaction flows — collaborating with NLP and engineering to flatten tool-call hierarchy and reduce cognitive load in agent flows.
Owned end-to-end QC pipeline: managed frontend engineering tickets, ran QC cycles actively, and guided QC team on bug prioritisation and ticket triage.
Led critical product decisions independently — credits & add-ons purchase flows, artefact structures (Reports, PaperTable, Web results, Code Snippets), file management with bulk export, citations system, and post-credit exhaustion flows.
Scoped and prioritised frontend execution from start to finish; coordinated with engineering and product to translate design specs into practical, shippable GUI.
Shaped the brand design layer and contributed to marketing direction in parallel with core product work.
Led design for the Recharge & Bill Payments (RCBP) POD — delivering high-impact features, IA revamps, and end-to-end product improvements at massive consumer scale, serving millions of users across India.
Spearheaded the industry-first introduction of Platform Fees on mobile recharges — a business-critical monetisation initiative shipped without disrupting the user experience.
Designed Guardian by PhonePe from zero to one — an end-to-end Risk Operating System for fintech orgs and banks, comprising a no-code real-time rule engine, shadow mode experimentation, ML-based fraud detection, smart case management integrated with govt. fraud reporting, and a centralised graph network for pattern analysis.
Designed a Component Dependency Graph tool for service mesh visualisation, real-time anomaly detection, alert noise reduction, and root cause analysis during outages — with context-aware dependency data per use case.
Designed a Generalised Authentication & Authorisation system powering almost all PhonePe production products.
Built an Enterprise Design System on top of Ant Design, standardising all public-facing enterprise applications; established a designer-developer collaboration framework adopted across the org.
Designed an Alert Management System with a no-code interface for PMs to configure business alerts and monitor on-call live updates.
Conceptualised and shipped a zero-to-one Sales Funnel management tool for MSP IT sales — integrated CRM, Quote Builder, Technical Assessments, Reports, and Analytics — resulting in 100+ paying customers in under a year and a $4.1M raise in early 2020.
As first hire, built the brand identity and design system from scratch, enabling product-market penetration in under 4 months.
Led research and design of a drag-and-drop document editor — the flagship feature — allowing customers to build sales proposals with text, media, e-signatures, and real-time distributor pricing; drove maximum sales conversions.
Delivered 50+ feature prototypes for onboarding and demos, contributing to 10× month-on-month growth in traffic and customer signups.
Ran weekly Design Sprints, managed IA with product and engineering, attended customer calls to capture feedback, and kept design consistently ahead of engineering for smoother deployments.
