Why Your Content Security Policy Might Be Useless - And How to Fix It
Learn how traditional CSP configurations can be bypassed and how to implement more effective security measures using CSP Level 3's strict-dynamic directive.
We're Tinkr Creative, a digital development studio based in Wales. We design and build apps and websites for organisations that want more than a good-looking site — from bespoke app development to full digital products, including bilingual English/Welsh projects. Performance is still at the heart of everything we build, but these days we're just as often brought in for bigger digital projects from the ground up. We're proud to be an award-winning studio.
It's always best to bring us in from the beginning, whether that's a new app or a new website. Early involvement means performance budgets, clear goals and key metrics are baked in from day one, so every design and feature decision is informed by how the product actually needs to perform for its users.
Already live? We can just as easily step into an existing app or website, optimise its performance, and help set goals and budgets to keep it on track. With an existing product you also have real user data to work with, which makes building a meaningful performance budget even easier.
Fine-tuning a digital project's performance can have a huge effect on conversions, and often makes the difference in achieving its goals. For this reason we're always keen to work with charities, not-for-profits and NGOs doing good in the world. We usually offer a discounted rate for organisations like this, and can occasionally offer pro bono work. So please do get in touch.

Many websites struggle with performance, so our tailored website performance optimisation is one of our most valued services.
If you have a live project that isn't quite performing as expected, I offer remote code review and audit, and can then advise on performance optimisations.
Digital consultancy can play a key part in the development cycle, especially in the early planning stages.
I have worked with many amazing people and organisations
