“ Hisma is one of the best iOS engineer that i've ever met. He has a lot of experience with iOS things and always update to the latest iOS technology. He has very deep understanding in Objective C. If you need a problem in Objective C or iOS things, go ask Hisma for a solution. Within the project, he could finish the task with high complexity in time. No wonder he is the iOS Senior Engineer of IceHouse! Keep up the good work bro! ”
Elsen Novraditya (Senior Android Engineer at Coral)
“ Hisma is a very passionate mobile engineer with vast knowledge on iOS platform. He's always eager to learn and will go the extra mile to get the job done. As a teammate, he's dependable and will back any member of the team that require his help. ”
Fauzan Emmerling (Engineering Manager at Coral)
“ Hisma gave me this advice when I was a junior: "Software engineering is a role playing game, where all of us compete to raise our skills". That sentence shows his enthusiasm for software engineering, and I've seen his actions reinforces this. As one of my early mentors, Hisma gave tremendous help during my baby steps in iOS development. He showed me the basics and helped me to navigate during my learning process - especially on how to keep up with the pace of iOS development. I still use some of his sources to train other iOS engineers until now. When it comes to work, Hisma is just as other Ice House engineers - he delivers high quality code on every project he worked on. He also walked the extra mile to deliver what's needed, which tells how he cared about quality. It's no-brainer to say that Hisma was one of Ice House's best iOS engineers. All in all, I am thankful to have him as one of my teammates and mentors during my early days in Ice House. I would gladly recommend Hisma to anyone who needs high quality code in their product - and want to have someone to show how to deliver it in their team ”
