Services

From a simple website to an advanced application

Start with what you need today. As your business grows, your website can grow with it.

Simple

Presentation website

A modern, fast website for a business, guesthouse, tradesperson or personal project. You can easily edit the content yourself.

The benefit: customers find you and get in touch on their own.

  • WordPress, easy content editing
  • Looks great on mobile, too
  • Basic SEO and fast loading

Advanced

Online store

A WooCommerce or custom-built store. Payments, shipping and orders connected so they run on their own.

The benefit: orders without manual retyping.

  • Payment gateways and carriers
  • Clear order management
  • Integration with other systems

Custom

Web application

Booking systems, client portals, internal tools. Software built around exactly how you work.

The benefit: the system takes over routine work.

  • Bookings and calendars
  • Client accounts and overviews
  • Automation of repetitive work

The foundation of every project

Testing, maintenance and security

  • Automated and manual testing
  • Regular updates
  • Backups
  • Monitoring and security

How I work

Four steps. No technical worries.

You don’t need to understand technology. I’ll guide you through the whole process, and you’ll know what’s happening at every step.

  1. No-obligation consultation

    Result: a clear plan and price up front

    We discuss what you need and what the new website or app should make easier. You get a proposed solution before any work begins.

  2. Design and development

    Result: regular previews

    I design and build a tailor-made solution. I show you progress along the way and work your feedback in right away.

  3. Thorough testing

    Result: a launch without surprises

    Before launch, I check everything on desktop and mobile – forms, orders, speed and security.

  4. Launch and long-term care

    Result: peace of mind

    I launch the site and keep looking after it: updates, backups and security. When you need a change, just drop me a line.

Quality

A bug on your website costs you customers. That’s why I test.

As a QA engineer, I know where bugs hide. Every project is tested before your customers see it – and regular checks continue after launch.

  • I test like your customers

    I go through ordering, booking and forms step by step, on desktop and mobile.

  • Automated tests keep watch

    They catch a bug after an update before a customer notices it.

  • Care after launch, too

    Updates, backups and security checks happen regularly, without you having to think about them.

About me

One person. The whole project.

I’m Tomasz Dziwoki, a developer and QA engineer. You don’t need an agency or a team of specialists: I design, build, test and maintain everything myself. You have one point of contact, and nothing gets lost between people.

I have been working as a developer and tester of web applications for the last 14 years. Before that**,** I ran an e-shop and managed an e-commerce company. All this experience helps me understand the needs and expectations of my clients.

Agency work

Contract work for digital agencies

As an external developer and tester, I contribute to many agency projects – delivering WordPress plugins, animations or testing. These projects belong to the agencies’ clients, so I don’t publish them here.

  • WordPress plugins
  • Animations
  • Testing (QA)
