Looking for someone to write a python script to auto complete icon captcha or bypass it.. He’s one of the most co-operative freelancers I’ve worked with. The quality of his work is top-notch. I really enjoyed working with him. Look forward to working with him again.

Urgent Smart Contract Code Review Hakan was extremely thorough in his code review of our smart contract, which we then published to the community. Not only did he run the code review and analysed it, but also held the devs accountable for fixing it, making himself an essential piece to our security. Would be happy to work with him again!
