During my career, I have worked with many clients but can't share links, names and any info in the contract. I am sure you know what is NDA if you come here.
But here are a few letters of recommendation:
Companies above are working with world web agencies as subcontractors. That's why I can't reveal the secret. Off-course I worked for companies without NDA but It was far ago and that work doesn't demonstrate my current skills.
You can contact me and I will describe you all my works without names.
