Building Digital Excellence
I design, build and audit web and mobile products myself — from the first idea to secure, high-performing software your business can rely on.
About Me
One developer, accountable for every detail
I'm Anna Sard, the freelance developer and consultant behind Thumbkind. I design, build and audit web platforms, mobile apps and the systems around them, working directly with founders and product teams across Europe and North America. No account managers and no handovers: the person you brief is the person who writes the code and ships your product.
My Mission
To help companies build software that is secure, fast and maintainable — and to make every technology decision transparent, so you always know what you are paying for and why.

- Mobile apps

01
Direct communication
You talk to me, not an account manager. One inbox, one decision-maker, an answer within one business day.
02
Personal accountability
I scope, build, test and ship every engagement myself — and I stay responsible for it long after launch.
03
Craft & detail
Honest estimates plus rigorous code review, testing and documentation on every deliverable.
