I will develop your shopify store apps, integrations and stock sync
About this gig
I build and fix Shopify stores for a living. Right now I develop a public Shopify app that syncs catalog, stock and orders for around 500 active stores, so I work with the Shopify Admin API, webhooks and real inventory problems every single day.
NEW ON FIVERR, NOT NEW TO THE JOB
This profile has no reviews yet because I just started here, and I am not going to hide it. I am pricing these packages well below what the work is worth because my goal right now is simple: prove what I can do and earn my first reviews. You get a senior Shopify developer at entry price, I get the review.
WHAT I CAN DO FOR YOU
-Complete store setup: theme, products, payments, shipping, mobile
-Fix what is broken: checkout errors, app conflicts, theme bugs
-Custom development: private apps, API integrations, stock sync with your ERP or supplier feed
HOW I WORK
Before starting I tell you exactly what I will do, what it costs and when it lands. If your request hits a Shopify limitation, I say so before you pay, not after. I reply within a few hours and I do not disappear mid-project.
Send me your store URL and what is going wrong. I will tell you straight, even if the answer is that you do not need me.
Respect third-party rights

FAQ
You have no reviews yet. Why should I trust you?
Fair question. I am new on Fiverr, not new to Shopify: I develop a public Shopify app that syncs catalog, stock and orders for around 500 active stores. Send me your store URL before ordering and I will diagnose your problem for free. You will know within one message whether I know what I am talking
Do I need to give you my Shopify admin password?
No, and please never send passwords to anyone on Fiverr. You invite me as a staff account (Settings, Users and permissions) with only the permissions the job needs, and you remove that access the moment we finish. For theme-only work a collaborator request is enough.
Which package do I need?
BASIC if your store already exists and something is broken. STANDARD if you need a store built and ready to sell. PREMIUM if you need custom development: an app, an API integration, or stock syncing with an external system. If you are unsure, message me and I will tell you the smallest package that
Do I have to pay for Shopify or apps separately?
Yes. My price covers my work only. Your Shopify plan, paid themes, third-party apps and domain are billed by them, not by me. I will tell you the real monthly cost before you order so there are no surprises later.
What do you need from me to start?
Store access, your logo and brand colors if you have them, your product data (a CSV or spreadsheet is perfect), and one sentence describing what success looks like for you. If you do not have product data ready yet, tell me and we plan the delivery date around that.
