one source, for everyone

Sound familiar?

  1. The list.

    One spreadsheet everybody needs and everybody maintains a little differently.

  2. The copy.

    Someone saves it locally. Now there are two versions of the truth.

  3. The hunt.

    Friday, 4 pm: which version is right? Nobody knows for sure.

It doesn't have to stay that way.

How replacing the spreadsheet works

What we build: custom software

Software that fits your process exactly – instead of bending your process to fit off-the-shelf tools.

What we work with:AngularReact / Next.jsTypeScriptC# / .NETTesting with Playwright

How a software project with us works

  1. Listen

    You tell us where it hurts. We keep asking until we really understand your process.

  2. Sketch

    We look at your lists and workflows and draw what the application could look like.

  3. Build in small steps

    You see results early and have your say before everything is finished.

  4. Look after and evolve

    After launch we stay: maintenance, extensions and a monthly work report showing what was done.

Who's writing: Mesut Barut

I was born and raised in Germany and worked there as a permanently employed developer. Since 2025 I have been running MeRa Yazılım from Bursa, Turkey – in German, with a time difference of just one to two hours.

Two web interface developers (Next.js) whom I trained myself work with me.

What that means for you:

  • One contact who speaks your language – including what's between the lines.
  • Almost the same working hours, hardly any time difference.
  • You talk to the person who writes the code.

MeRa = Mesut + Rabia · yazılım = software

How working with our team in Bursa works

Tell us where it hurts.

A few sentences are enough. Mesut Barut replies personally within one working day – no ticket, no call centre.

  • Initial call: 30 minutes, free
  • Fixed price for new projects, no hidden costs
  • Your application runs on servers in Germany
  • The GDPR applies to us directly
