Hi I'm Petr.
I help business owners feel in control of their website again.
I started Appvalanche because I saw too many business owners feeling stuck with their websites.
Either they’d overpaid an agency and didn’t feel heard. Or they’d tried to do everything themselves and ended up overwhelmed.
I’ve been in web development and digital strategy for years, working with local businesses, growing companies, and public sector projects. What matters most to me is helping business owners FEEL IN CONTROL AGAIN.
I’m based in South Wales and work closely with businesses across Newport, Cardiff and further afield. I care about local growth and building long-term partnerships, not one-off transactions.
Appvalanche isn’t about flashy promises.
It’s about building digital foundations that actually SUPPORT YOUR BUSINESS GOALS.
