Beyond e-commerce

My core focus is headless Shopify — but I've shipped production code across different stacks and domains. Here's what else I've built.

Smart Carts

10 months3-person team

Shopify embedded app for real-time cart management. Live cart monitoring, abandoned cart recovery, and dynamic cart modification — all from the merchant dashboard. Built the backend API with NestJS and Express for real-time cart processing, integrated Shopify Admin and Storefront APIs, and designed MongoDB schemas for cart state tracking.

Optimal A/B Testing

8 months3-person team

Split-testing platform for Shopify product listings — titles, descriptions, images, and prices. Built the full-stack app with statistical analysis logic for determining winning test variations, Redis-based caching for real-time A/B results and session management, and an analytics dashboard for experiment visualization.

Antla AI Virtual Try-On

6 months3-person team

AI-powered virtual try-on for Shopify fashion brands. Customers see themselves wearing products with picture-perfect compositing. Configured AWS infrastructure (S3, Lambda) for image processing and AI model serving, built responsive UI for the try-on experience, and optimized the image processing pipeline for fast rendering on mobile.
