## About

I'm a senior programmer with 25 years of experience, so I work fast and deliver high-quality, end-to-end tested code. I only use TDD (test-driven development), which eliminates the possibility of leaving bugs in the app. You can see samples of my work at www.e-stonia.co.uk/en, and you can also see a link from there to my GitHub repo to see my coding experience and style.

With the help of AI agents today, I work at a speed of 2-3 developers, so the bid would have been about 2.5x higher years ago. Now I can even compete with younger and less experienced programmers, so you will be getting a top senior developer for the cost of a junior.
