About this gig
You need your store to do something no app in the App Store does.
I am a full stack developer in Turin and a Shopify Partner, building Shopify apps and integrations since 2021.
I build on Remix, the framework Shopify uses for its own app template, so the app fits Shopify's embedded admin, sessions and authentication the way Shopify expects.
What I build:
- Private apps for a single store, and public apps for the App Store
- Embedded admin screens your team can actually use
- Admin API and GraphQL integrations
- Webhooks, background jobs and scheduled tasks
- Connections to systems outside Shopify: ERPs, CRMs, pricing feeds, logistics
- Shopify Flow automations and bulk operations
- Billing and subscription logic inside the app
Why me:
- You own the repository and the deployment from day one
- Built to pass Shopify's review, not just to work on my machine
- I tell you the monthly running cost before we start, not after
- Built so a new Shopify API version is an update, not a rebuild
Not sure whether you need an app at all? Tell me what it has to do in plain language. Sometimes the answer is a Flow automation costing a fraction of this, and I will say so.

I am Alex, a freelance software engineer based in Turin, Italy, with a computer science degree and six years of client work.
Shopify is where most of my 88 five-star reviews come from: custom code and sections, theme and app fixes, Remix apps, and hand-coded storefronts. I also build full web platforms end to end — Next.js, React, TypeScript, Python, Supabase — and AI systems on top of them, from small n8n automations to document analysis and reporting platforms.
Tell me what you are trying to build and I will tell you honestly whether I am the right person for it.

FAQ
Can you build both private and public Shopify apps?
Yes. A private app is built for your store only and skips Shopify’s review. A public one is listed on the App Store, used by many stores, and needs review, billing and mandatory webhooks. Most people who ask for public actually need private.
What do I need to get started?
Your store URL and what the app has to do, in plain language rather than technical terms. If it has to talk to another system, tell me which one and whether you have API access to it. Then your collaborator request code.
Can you integrate third-party systems?
Yes, and it is most of what I do: ERPs, CRMs, accounting systems, pricing feeds, shipping and logistics platforms, marketplaces. If it has an API or can send a webhook it can be connected, and I will say upfront if their API is the weak link.
Can you publish my app on the Shopify App Store?
Yes, if a public app is genuinely what you need: review requirements, the mandatory GDPR webhooks, the billing API and the listing itself. The review outcome and timing are Shopify’s decision, not mine, so I will not promise you a date.
Are there ongoing costs to any apps you develop?
Yes, and you should know the figure before you order rather than after. A Shopify app is a hosted web application, so there is hosting and a database. I deploy on your own accounts, so the cost is visible and yours, and it is small for most single-store apps.
Can you handle hosting and deployment?
Yes. I set it up on accounts in your name, with environments, environment variables and a deploy you can roll back. You own the deployment from day one and nothing depends on an account of mine staying alive.
Do you use GraphQL or REST?
GraphQL against the Admin API, which is what Shopify now builds on and what performs properly at volume, with REST only where an endpoint has no GraphQL equivalent. The app itself is Remix with Polaris, so it fits the Shopify admin around it.
Do you provide support after delivery?
Fourteen days for anything not working as agreed, included. After that it is separate work and I will quote it. If you want someone looking after it as Shopify changes their API each quarter, say so and I will scope that properly.
