Testimonials

I first worked with Harry at VoicePing, where he demonstrated exceptional coding skills as a full-stack engineer and excellent collaboration abilities with other team members. He is a very sincere person, always putting in considerable effort and showing a strong willingness to learn new coding techniques and implementations. Harry consistently strives to deliver what is required, contributing significantly to the team's spontaneous workflow. Convinced of his abilities, I recommended him for a position at my current company, Antaa where he worked well at new projects as well.
