Services

Software that runs in the browser, no installing it on every computer. I start where things are stuck, not with everything on day one.

Website

Where your business introduces itself.

What you do, who you do it for and how to reach you. It holds together on a phone.

If you sell products, cart and checkout live under the same roof; I don’t build one site for the catalogue and another for the till.

You change the text, services and photos yourself, without waiting for me for every small edit.

Custom software

Off-the-shelf menus don’t look like your day.

Production orders, dealer orders, service forms, approval chains. Whatever you call it, that’s what the screen is called.

Work that lives in spreadsheets, on paper or in programs that never agree, brought into one place.

Stock and ERP

Goods come in, get counted, reserved and shipped.

When an order is opened, stock is reserved; when it ships, it’s deducted and the amount is posted to the customer account.

E-invoicing and e-dispatch notes sit next to this flow instead of being pasted into another window.

Barcodes, serial numbers, warehouse transfers and stock counts connect to the same record when you need them.

CRM

The memory of your sales team.

Calls, prices, next follow-up. When people change, history doesn’t stay on someone’s personal phone.

Managers see from one list who is chasing which deal.

Integrations

Stop copying data between programs by hand.

I move data automatically between your online store, accounting software, shipping carrier and payment provider.

Connecting enterprise clients’ systems to the platform was my everyday work at Insider.

What I build with

Underneath: PHP, Laravel and MySQL; Go for services and React or Vue for interfaces when needed. Invoices and dispatch notes connect to whichever e-document system your accountant uses.

What comes later

  • Dealers enter their own orders, with prices and discounts on screen.
  • The field team opens the same record on their phones.
  • Leave, attendance and payroll, once the team grows.

Frequently asked questions

How long does a project take?

It depends on scope; I pin down the timeline in a written proposal after our first call. A small company website usually takes a few weeks. For business software like orders or stock, I launch the most needed part first and add the rest once you’re using it.

Where do you work?

I’m based in Denizli, Turkey, and work remotely with clients across Turkey and abroad; I can visit on-site when needed.

Can it connect to my existing accounting software?

Usually, yes. I look at the software’s import/export or API options; e-invoicing and e-dispatch connect through the e-document provider you already use.

Who makes changes later?

You change content such as text, photos and prices from your own admin panel. New screens or features are discussed separately.

Whose server does it run on?

On your own server, or on a server I set up and manage for you. The code and data are yours.

A few sentences is enough.

Tell me what you sell and where things get stuck today. The website, the warehouse, sales follow-up? If it’s a fit I’ll call you; I give a price once the scope is clear.
