Hi, I'm

Tarun Kataria

Software Engineer with 1.5+ years building and shipping React Native iOS and Android apps for 75+ Shopify D2C brands, plus full-stack work across React.js, Next.js, Node.js and GraphQL. I build custom React Native blocks that brands drop straight into their apps, and spend the rest of my time deep in SDK integrations, attribution pipelines, conversion funnel optimisation and production firefighting. Lately that has extended to LLM-powered internal tooling — including CRM agents that make debugging merchant integrations far quicker.

Building the React Native mobile layer that 75+ Shopify D2C brands sell through — from custom native blocks and SDK plumbing to conversion funnels and peak-sale firefighting. Named Employee of the Month in January 2026.

  • Engineered, deployed and maintained React Native iOS and Android app features for 75+ Shopify D2C brands, including Minimalist, Libas, Superbottoms, The Bear House, mCaffeine and The Face Shop.
  • Resolved and shipped 260+ production tickets across mobile integrations, custom UI/UX design blocks, store builds and checkout optimisations at roughly a 90% completion rate.
  • Delivered 130+ third-party app integrations and SDKs over REST APIs: CRM and push automation (CleverTap, MoEngage, BiteSpeed), express checkouts (GoKwik, Shopflo, Fastrr) and review platforms (Judge.me, Loox).
  • Architected end-to-end analytics and attribution pipelines (GA4, Facebook Pixel, AppsFlyer, Branch.io, Microsoft Clarity) for high-scale apps, debugging event drop-offs to keep ad attribution accurate.
  • Optimised Cart, PDP and PLP conversion funnels with dynamic cart progress goals, native upsell blocks, custom variant pickers and React Native deep-link routing for Libas, Powerlook and Zavya.
  • Held engineering SLAs through peak sale events by debugging and resolving 14+ P1 release blockers and 75+ P2 production issues for high-traffic merchants in an Agile team.
  • Built LLM-powered CRM agents that make debugging merchant CRM integrations far quicker, surfacing event and payload issues across CleverTap, MoEngage and BiteSpeed instead of digging through logs by hand.
