Experience
Skills
- Business Analysis consulting. A key element for successful and reliable app is quality requirements. If youāre starting the app from scratch, with only business need or an idea, I can help you with requirement elicitation as well as creating specification and adjusting it for changing conditions.
- Technical solutions investigations. Mobile developers nowadays can rely on a huge toolkit of solutions that can be easily integrated into an app. Machine learning, AR, IoT, GPU computation provide great power that previously was only available for desktops and servers.
- Architecture development. Every business needs to react to the changing conditions fast and efficiently, so needs its app. Well-thought out architecture depends on technical nuances of specific app as well as on requirements it meets. That helps to make incremental changes efficiently and prevent losses in codebase quality.
- Native-oriented app development. Built-in iOS frameworks can solve a wide range of technical tasks while keeping code optimized and easy to maintain in future. Years of freelance development helped me to collect a number of tested solutions for features the typical apps may need.
