## Solutions (common problems)
- [Why is my website so slow — and what is it costing me?](https://sedenko.net/solutions/slow-website): A slow site quietly leaks money: visitors bounce before it loads, Google ranks you lower, and every ad click buys fewer conversions. The good news is that speed is fixable, and the fix is measurable.
- [My WordPress site is old and outdated — what should I do?](https://sedenko.net/solutions/old-wordpress-site): An old site doesn't just look dated — it's slow, awkward to update and quietly undermines trust with every visitor. The fear is always the same: "if I rebuild it, will I lose my Google rankings?" You don't have to.
- [My team wastes hours on manual work — how do I fix it?](https://sedenko.net/solutions/manual-business-processes): As a business grows, the busywork grows with it: chasing leads, copying data between tools, sending the same emails, building the same reports. It feels normal, but you're paying salaries for work software should do.
- [My website gets visitors but no leads — what's wrong?](https://sedenko.net/solutions/low-conversion-website): Getting traffic and getting customers are two different problems. A site can look fine and still convert almost nobody, because visitors don't immediately understand what you offer, why it's for them, or what to do next.
- [I built an app with AI, but it's not ready for real users](https://sedenko.net/solutions/ai-prototype-not-production-ready): AI coding tools get you to a working demo fast — then stall at exactly the parts that make a real product: secure payments, correct data, access control, and code you can keep building on. That's normal, and it's fixable without starting over.
- [The EAA accessibility deadline is here — is my website at risk?](https://sedenko.net/solutions/eaa-compliance-deadline): The European Accessibility Act is now enforceable. If your site sells products or digital services to EU consumers, accessibility is no longer only a UX improvement — it is a compliance and business risk. The fix is not an overlay widget. It is accessible code, forms, navigation and content.

## Audiences

## Case studies

- [wMenu: a multi-language QR menu restaurants can run themselves](https://sedenko.net/case-studies/wmenu): wMenu lets restaurants and bars publish a digital QR menu in several languages — no app, always up to date.

- [GetInData: making deep Big Data expertise legible from the outside](https://sedenko.net/case-studies/getindata): GetInData works at the hard end of data engineering.

- [Marquez: making data lineage something you can follow with your eyes](https://sedenko.net/case-studies/marquez): Marquez is an open-source metadata and data lineage service.
