We finish what we start.

Software, websites and map-based applications, built by an engineer and kept running after launch. We measure before we promise, and we don't leave work half done.

Sound familiar?

The situations we are built for.

  • A freelancer or agency disappeared halfway through.
  • Your map or data app is slow, and nobody really owns it.
  • You need one person who can handle the database, the backend and the front end.
  • Your data lives in spreadsheets and nobody trusts the numbers.
  • You want to use AI but don't know where it actually helps.

One engineer, one point of contact, from the first call to maintenance.

What we do

Five services, one point of contact: the person doing the work.

Software development

Custom web applications, APIs, integrations and automation. We move work that lives in spreadsheets into a proper system.Python, Node.js, PostgreSQL, PostGIS

Websites

Fast, mobile-friendly websites you can update yourself, including pages with maps and live data.Maintenance and security updates after launch, too.

AI consulting

We find out which of your tasks AI can speed up and which it can't. Then a small pilot and a short training for your team.Your data goes to no tool without your say.

Business email

Email on your own domain: setup, migration, and the domain settings that make it harder for others to send fake email in your name.SPF, DKIM, DMARC

Digital advertising

Google and Meta ads with measurement set up first, so each month you see how many leads and customers the spend brought in.Currently for clients in Türkiye.

Maps and location data are our specialty.

GIS and live bus tracking for a municipality. The data layer of a US land and real estate platform. Wetland and species maps in Australia. If location matters in your work, we turn it into maps and reports.

  • Interactive maps and spatial dashboards
  • Fleet, field team and asset tracking
  • Spatial analysis with PostGIS
  • GIS applications for public bodies and nonprofits

How we work

The route on the map. Four stops, every project.

  1. Listen

    We listen to the problem and look at what you use today. It starts with a 30-minute call.

  2. Measure

    We measure where things stand, then send a written quote: what's included, what isn't, when, and how much.

  3. Build

    We build. You get regular notes on what's done and what's left, from the person doing the work.

  4. Finish

    We hand over and stay: maintenance and a monthly report if you want them.

Pricing: every project gets its own written quote after the first call: what's included, what isn't, when, and how much. Maintenance after launch is a separate line if you want it.

Selected work

Projects we have permission to share.

About

Sebat means seeing a job through to the end.

I'm Seb, a computer engineering graduate of Sakarya University. I've been writing software since 2010: eleven years building GIS and web systems for Sakarya Metropolitan Municipality, and since 2022 running the data layer of a US land and real estate platform.

Over those years I learned that what wears a business down isn't technology. It's half-finished work and broken promises. That's why Sebat Dijital exists.

You talk to the person doing the work. We say up front what won't work, we measure before we promise, and we finish what we start.

What we stand for

Honesty
We say “we don't know” when we don't, and never give a number we haven't measured.
Sincerity
We work for your results, not for show, and we don't sell what you don't need.
Loyalty
Long-term work with the same person, year after year.
Perseverance
Sebat, in Turkish. We finish what we start.
Solidarity
When a job needs another specialist, we bring in the right partner; your point of contact stays the same.

Let's talk about your project.

In a 30-minute call we'll tell you plainly what's possible and what won't work.
