5 out of 5 stars
Stelios is a great person, willing to be very generous with his time and wisdom. His quality of character has attracted a welcoming and helpful community of like-minded people to engage with and learn from. His insight and support was incredibly helpful at a time when I was really struggling. He fostered a renewed passion in me for cybersecurity and volunteering. He strikes me as someone to leave a lasting positive impact in the lives of everyone with whom he crosses paths. I am grateful to be one of those people and hope to continue to pay it forward. Thank you Stelios for the work you put into helping others. I would recommend anyone with an interest in cybersecurity/tech and/or animal welfare and music to reach out.
