Experience

Funimate

https://apps.apple.com/us/app/id844570015
Funimate is an advanced video creativity/editing application with a huge number of users. It enables users to make smooth transitions between images and videos and also to add background music and special effects, and more.

I worked on the core features such as setting the video speed, adding/trimming audio files to edits, and bordering. I also implemented the Elements feature, which basically lets users store view components (layers) and reuse them or share them with others. In addition, I built an internal analytics tool to collect user data to improve the experience.

World Mobil

https://apps.apple.com/tr/app/id634054863
I built a Swift-based, native banking application for YapiKredi Bank. It allows users to perform banking operations that fulfilled the bank's needs.

App Features:
• Manage installments
• Postpone payments
• Set credit card limits
• Apply for credit cards
• Close credit cards
• Activate accounts
• Track campaigns and more

IsCep

I implemented various features (bill payment, currency converter) and Firebase integrations for IsCep (an app aimed at to allow bank customers to perform any operations with their accounts and credits in Turkey). I also added tests for each development phase, fixed bugs, and improved existing flows.

Ottolock

I developed a native iOS application for smart-home lock kits, which communicates with an electronic lock via Bluetooth. The application enables users to lock/unlock their homes at any time, allow others to unlock their home, and track lock activities.
