I’m Kseniia.

I make complicated WordPress work clearer.

I’m a senior WordPress developer with 8+ years of experience across custom themes and plugins, WooCommerce, frontend development, performance, security, integrations, and large-scale maintenance. My React and UI/UX background helps me consider the whole system: code, interface, content workflow, and the business relying on it.

I’m based in Novi Sad, Serbia, working remotely with clients worldwide.

High level of communication

Clear updates, direct answers, and shared context throughout the project.

A clear process, even when the work is complicated.

The details change from project to project. The important part is that you always know what happens next.

Start a project brief
  1. Share the context

    Send the website, goals, current problem, desired timeline, and anything else that will help me understand the situation. A perfect technical brief is not required.

  2. I assess the work

    I review the requirements, existing setup, dependencies, and risks. If something needs investigation before it can be estimated responsibly, I’ll say so.

  3. We agree on scope

    You receive a clear proposal covering priorities, deliverables, timing, responsibilities, and the recommended engagement structure.

  4. I build, test, and keep you updated

    Work happens in the appropriate environment with testing and review points that fit the project—not meetings for the sake of meetings.

  5. You get a clean handover

    I deploy or hand over the completed work with the documentation and context your team needs. Ongoing support can be agreed separately.

Custom development, careful improvements, and support that makes sense.

I can build from scratch, join an existing project, or step in when a WordPress site has become slow, fragile, or unnecessarily difficult to use.

Senior expertise without the extra layers.

You speak directly with the developer doing the work. That means less lost context, faster decisions, and clear responsibility from the first review to the final handover.

I look beyond the ticket.

I’ll solve the issue you bring me, but I’ll also check what caused it, what it affects, and whether there is a more sensible route.

Communication stays clear.

You’ll know what I need, what I’m doing, and where the work stands. Technical detail is available when it helps—not used as decorative fog.

The result has to survive real life.

Clean code matters. So do content editors, mobile users, integrations, future updates, deadlines, and the next developer opening the project.

Your workflow does not need replacing.

I can work with your existing team, repository, staging setup, project tools, and delivery process.
