Sebi is a miracle! I found this site while tire kicking. I’ve been scared to death of this project for almost a decade and have been procrastinating the whole time. I posted an ad asking if anyone could help me (basically let me pay them to do it for me) and Sebi came to the rescue. His knowledge is unsurpassed, his ethic is impeccable, and his drive and motivation to be here is unbelievable. Sebi saw my ad and found me. He DM’d me with a river of ideas and I could just tell he’s the guy for my project. He’s just completed the main body of the work and I could not be happier. Sebi has made my dream into a reality. I promise I’d have kept tire kicking another decade without him. He’s truly the reason my project became reality. If you need help, you’re doing yourself a disservice to skip over Sebi. This guy is unparalleled at what he does. Do yourself a solid and just hire him for your needs.

Sebastian was prompt, very very knowledgeable, and fantastic person to help me deal with a particularly weird cors error that had plagued three full stack developers for 15 hours. Thank you so much Sebastian, you're a life saver.
