In an interview with The Punch, John Oseni replied to online reports that claimed he was offered employment by a firm in Italy. He said most of the jobs he gets are based on referrals and he actually worked for two companies in Italy; Flywallet and Cryptonite.

At age 14, John Oseni had his first exposure to Tech. This was when Green Garage, an Akure based Tech Organisation visited his school, Command Day Secondary School, to teach Students about basic computer hardware. For John, this was the spark. He became so much interested and then engaged in the Competition Green Garage organized for Students where he emerged co-winner with another female student amongst other 80 Students who competed.

Few weeks after this experience, John reached out to Green Garage for his prize as co-winner but they offered to teach him lessons for a week in exchange.
