Project History
Zaplet AI
http://zaplet.ai/A Shopify app that leverages AI and allows customers to browse the store inventory, check order status, and place orders via WhatsApp messages. It uses the Meta WhatsApp Business API to manage all messages and provides a chat platform that allows the store owner to monitor chats and take over as needed. It also allows store owners to send promotional messages in bulk and set up automations based on triggers provided by Shopify.
Dropshipping App for Shopify Stores
A return on revenue (RoR) based Shopify application that is connected to a merchant account on AliExpress. The app helps sync product data from AliExpress to Shopify and order data from Shopify to AliExpress. I was the lead on this project.
Shopify Plus Stores for B2B and B2C Brands
Business-to-business (B2B) and business-to-consumer (B2C) Shopify Plus stores are synced to other stores owned by the same company. They sync inventory and price data with adjustments. I have implemented a custom shipping price calculation to the main store using tags and Shopify script editor, a custom search feature to find products using synonyms, and a custom pick-up or delivery feature.
Shopify App to Sync Data Between Stores
A Shopify-based custom app that syncs data between stores with the same products and handles prices and inventory levels. The app also syncs orders between the stores to manage the tracking info and inventory levels.
Home Page for Shopify Website
I developed a pixel-perfect home page for a brand based on the provided designs. The design was also converted into tablet and mobile screens and adjusted to accommodate any other kind of screen as well.
