    In my 10 years of professional experience as a software developer at a software company, I have worked on several medium-sized and small-sized web solutions and mobile applications. In my projects, I use modern technologies that make the development process easier and faster. I extensively use version control systems (GitHub) and issue trackers (JIRA, TRELLO) to ensure that no details are missed and to achieve well-coordinated teamwork. For team communications, I prefer to use Slack. My usual workflow for software development includes: . Understanding the job and documentation/estimation . Initial setups (TRELLO board, repository, code setup) . Development . Delivery using ad hoc builds/server . Upon request, I can deploy the application to the App Store (for mobile apps) . Upon request, I can deploy the web solution to a server (AWS, Digital Ocean, etc.) (for web solutions) . As a professional programmer, I always aim to make my projects bug-free, and I almost always use tools to track crashes, such as Crashlytics. I offer free support if the project cost exceeds the agreed-upon amount. I am happy to help discuss ideas, make feasibility/future plans, and provide architecture. My core performance specialties are: . Research and development . Web API/REST API . Photo/video manipulation (iOS) . Client/server application (iOS, Android) The following are the technologies I have worked with in the past: HTML5, CSS, ReactJS, React Native, MySQL, iOS, Android, Admob, PHP, JAVA, JavaScript, AngularJS, NodeJS, Yii/Yii2, Bubble.IO, Amazon Web Services (S3, EC2, Lambda, Cognito, DynamoDB, Elastic Beanstalk, CloudFront, IAM), Google Analytics
