# Custom e-commerce development for stores that have outgrown the template.

> Enterprise e-commerce development and e-commerce platform architecture — Adobe Commerce and Magento 2, headless storefronts, complex catalogues, B2B pricing and a checkout that holds on campaign day. I am the architect and the engineer: one person accountable for how the platform is built, integrated and kept fast.

## What custom e-commerce development covers here.

Not a theme and a plugin list. The platform layer an operation runs on: catalogue, pricing, checkout, orders, and the systems behind them.

- **E-commerce platform development** — Multi-store and multi-currency structures, complex catalogues, attribute sets and product configurators built as platform architecture rather than as extensions bolted on top.
- **Magento custom development** — Custom modules and Magento extension development where the business rule does not exist in the platform — priced tiers, approval flows, quote handling, custom order states.
- **Headless and PWA storefronts** — Magento headless development over GraphQL with a Next.js front end — used where the storefront needs its own product logic, not because headless is fashionable.
- **Checkout, payments and carriers** — Custom payment gateway integration with local banks and providers, plus shipping and logistics integration so every order leaves the system without a manual step.
- **Magento performance optimization** — Catalogue indexing, caching layers, queue design and infrastructure tuned against real campaign traffic — measured before and after, not asserted.

## The problems that bring people here.

Most enquiries do not start with a technology. They start with a symptom on a Monday morning.

- **The store slows down exactly when the campaign starts** — Traffic arrives, indexing and caching cannot keep up, and the paid traffic converts on a slower page than the test one.
- **Checkout dead ends nobody can reproduce** — A gateway times out, a shipping rate fails silently, and the order is lost between the two — visible only in the revenue.
- **Every price change is a developer ticket** — B2B tiers, customer-group pricing and campaign rules were written into code instead of configuration, so the commercial team cannot move.
- **The catalogue has outgrown the platform** — Tens of thousands of SKUs, variants and configurable products that reindex slower every month.
- **A build that has already slipped** — A replatform or migration that stalled, and the date the business already announced is still on the calendar.
- **Nobody owns the architecture** — Three agencies have each added a layer, and no single person can now say how an order actually moves through the system.

## Commerce systems already delivered.

- **Frankenspalter (frankenspalter.ch)** — A Magento backend tuned for thousands of orders a day: catalogue indexing, caching, order processing and ERP integration that stay up on campaign days.
- **Dcey (dcey.com.tr)** — A headless Next.js storefront over Magento GraphQL, with rental date ranges and availability built into the transaction itself.
- **Edip Saat (edipsaat.com)** — Store, ERP and warehouse reporting one stock figure, with payments and order handling automated end to end.

## Questions people ask.

**Do you only work in Magento?**
No. Magento and Adobe Commerce are where the certification and the deepest experience sit, and they are the right answer for large catalogues and complex pricing. Where a business does not need that weight, the storefront is built in Next.js against the systems it actually has to talk to.

**Can you take over a build somebody else started?**
Yes, and it is a common way projects start here. It begins with a two-week technical audit: what the system does today, where it fails, what can be kept, and what the realistic date is. The audit is written down and it is yours whether or not the work continues.

**Who owns the code and the documentation?**
You do. Repositories, architecture notes, runbooks and a weekly changelog are handed over as your assets, so your team — or the next engineer — can carry the system without me.
