Nocturn

Studio

A small studio, on purpose.

Nocturn is led by Yiğit Ertürk, a product engineer who designs, builds and operates every project end to end. No account managers, no hand-offs — the person you talk to is the person writing the code.

Why small

Most software projects fail in the gaps: between designer and developer, between developer and whoever runs the servers, between the agency and the client’s own team. We close those gaps by owning the whole path.

It is also why most of the work on this site is our own products. Running them is where we test the patterns we later bring to client projects — database-enforced rules, checks on every release, and pages that earn search traffic without a content team. It keeps us honest about what software costs to run for years, not weeks.

Principles

Five habits that show up in every project.

  1. 01

    Rules belong in the database

    If a constraint matters — money balancing, history not changing, one customer never seeing another’s data — it is enforced where the data lives, not only in application code that a later change can reopen.

  2. 02

    Every deploy gets checked

    Health, API contract and SEO checks run around each release. When a check fails after a deploy, the previous build comes back automatically.

  3. 03

    Say what is not done

    Roadmap items are labelled as roadmap. A demo never pretends an integration exists, and a sales page never lists a feature that only works in a slide.

  4. 04

    Boring tools, used carefully

    Widely known technology that is easy to hire for and easy to hand over. The interesting part should be your product, not our stack.

  5. 05

    Leave it maintainable

    Tests, a short runbook and readable code come with every project, so another team can take over whenever you want them to.

Working together

Terms you can plan around.

Start a project

Fixed-price milestones

Work is split into milestones with a price and a definition of done. No open-ended hourly billing unless you ask for it.

You own the code

Repository, cloud accounts and domains are yours from day one. Nothing is held back as leverage.

Maintenance is optional

After launch you can keep us on a monthly plan, take it in-house, or hand it to another team. No subscription lock-in.

Time zone

Istanbul time (UTC+3): a full overlap with European working hours and the morning of the US East Coast.

Communication

In English or Turkish, written first. Weekly demo, shared tracker, and a direct line to the engineer.

Confidentiality

NDA on request before any detail is shared. Client work is only shown publicly with permission.
