Departments

What I take on

Three kinds of job. Each one says who it is for and what it includes.

01

Who this is for

Founders and small businesses.

Marketing sites and landing pages

A small site on your own domain, built to load fast on a phone.

What you get

  • Design, or a build from your designer’s files
  • Content you can edit yourself, without breaking the layout
  • A contact form that arrives in your inbox
  • Romanian and English, with the diacritics right

Typical shape

We agree the scope in writing and I quote one fixed price for it. Most sites land between €3,500 and €6,000, depending on page count, languages, and whether the design starts from a blank page.

From€3,500

02

Who this is for

Startups and scale-ups with something already in market.

Product interfaces and web apps

Dashboards, settings, billing screens, invite flows, audit logs, and the API behind all of them. I build the empty account on day one, the row that is still uploading, and the button a viewer can see but cannot press.

What you get

  • A typed client against your API, so the compiler catches shape mistakes
  • Fetching, caching and invalidation you can follow in the code
  • Real time views where the data changes fast, and polling everywhere else
  • Loading, empty, error and permission states designed up front
  • Search and filters that survive a reload
  • CSV export, because somebody always asks for it
  • A record of who changed what
  • A component library your team can extend
  • Tests on the paths that would otherwise cost you a weekend

Typical shape

Work starts with a paid scoping week. €2,500 buys a written scope, a plan and an estimate you could hand to any other developer, and it comes off the build if you go ahead with me. After that the work runs in phases, each ending in something merged and usable.

03

Who this is for

Teams with a codebase and a backlog.

Frontend support for existing teams

This is the work that never reaches a sprint board. The component library has been forked more than once because somebody needed one more prop. The bundle is heavier than it was last quarter and nobody can name the commit that did it.

What you get

  • A frontend audit ranked by what each problem costs to leave alone
  • Design tokens and components your designers recognise
  • Performance work measured on real devices, with before and after numbers
  • Accessibility to WCAG 2.2 AA: focus order, contrast, labels, screen reader passes
  • Migrations off a framework version nobody wants to touch
  • Code review while your own people ship features
  • Time on whatever is blocking the release

Typical shape

Start with the audit: a fixed €2,500, delivered in about two weeks, and yours to act on whether or not we work together after it. Anything longer is booked in two-week blocks, quoted once I have seen the codebase.

Before you ask

  • Do you work with agencies, or only direct clients?

    Both. With an agency I work inside your process and you keep the client relationship. With a direct client there is nobody in between.

  • Can you work with our designer, or do you design too?

    Either way. If you have a designer I build what they drew, exactly. If not, I do the design as well.

  • What happens after launch?

    The repository and the accounts are already yours, so nothing is owed. Most sites need someone for the changes that come after, and that is a monthly arrangement, separate and much smaller.

  • Do you use AI to write the code?

    Yes, daily. It writes faster than me and is wrong more often, so I read every line.

  • Will it work in Romanian?

    Yes, with the comma-below ș and ț rather than the Turkish cedilla most sites ship instead.

  • How do you charge?

    Fixed price for fixed scope, milestones for phased product work, blocks of days for team support.

Email works best. A few sentences are enough.
