Sumer Dabby
Shopify Expert & Shopify App Developer
Full-Stack Engineer (MERN)
Shopify Expert and Shopify App Developer with 5+ years of experience building and scaling conversion-focused stores. I ship custom themes in Liquid, private and public Shopify apps with Remix and the Admin/Storefront APIs, and headless storefronts — backed by full-stack MERN engineering for the systems behind them.
Who is Sumer Dabby?
I am a Shopify Expert and Shopify App Developer based in Mohali, Punjab, India. I work as a Software Engineer — Shopify & Full-Stack — at Tech Prastish Software Solutions Pvt Ltd, and this site is my official portfolio: live Shopify storefronts, a custom subscription app, and a MERN healthcare platform.
Searches for “Sumer Dabby”, “Sumer Dabby portfolio” and “Sumer Dabby official” should land here. I am not an agency, a founder-of-record for a SaaS product, or an AI automation shop. The work is Shopify themes in Liquid, Shopify apps in Remix, and full-stack MERN when the product is a platform rather than a store.
The work, in one paragraph each
Shopify themes: seventeen live storefronts. Kids furniture in the UK, ride-on luggage across six markets, Australian fashion rental, Italian mattresses, GCC jewellery with Arabic RTL, US pet care and luxury tile, US hot sauce and tea, Canadian kitchen organisation, global automotive carbon fibre. The common thread is Liquid that survives more than one language and one currency.
Shopify apps: a custom subscription app for ThriveMeals on Remix, GraphQL and AWS Lambda — skip, pause, swap, and billing that does not keep a server warm between renewal dates. MERN: Healthy-You, a US healthcare platform with telehealth, specialist matching, FSA/HSA eligibility and RBAC across patients, advocates and practitioners.
