• Business Analysis consulting. A key element for successful and reliable app is quality requirements. If you’re 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.

Being a self-employed developer helped me to increase working efficiency and attentiveness. My top priority is achieving predictable result in terms of time and quality.

I had been working as a full-time developer from 2015 to 2018. Being a part of large distributed teams helped me to gain both communication skills and ability to write easy to read and mantain code with industrial degree of quality.

Four years of business analysis experience allowed me to participate in all major BA activities: requirement elicitation and management, domain analysis in both complex corporate systems and agile-managed startups.
