I.R.
    Lead Fullstack Developer
Expert Full Stack Developer (Dart, Flutter, Angular)

Hi! Thank you for reviewing my profile.

I am a lead java developer with 14 years of experience and Master’s Degree in Computer Science. Worked with top companies like Gameloft, Ferrari, UBC, CSX.

Now I'm specializing in Dart, Flutter, Angular and I see great potential in these technologies: with Dart you can have 3 clients to your product (iOS, Android and website) much quicker and easier than following a regular approach (building separate native clients). If compared with React Native - Flutter is much faster and Dart is much superior to JavaScript. Dart gives developers a great opportunity to write code once and then share it across clients easily. This approach saves a significant amount of my customer’s time and money.

My passion is to provide my customers with a product that will help them grow their business successfully and improve revenue stream. I care about all the details of my projects and invest my experiences, creativity, and knowledge to achieve the best results. In-depth study of customer's and user's needs allows me to develop sustainable solutions for you to meet your business goals.

I am primarily looking for an opportunity to build a long-term relationship with great clients on ongoing projects.

I am honest and do my best to provide you with a completely transparent and qualified service, as you are expecting. Be sure that with me your project will be in safe hands.

I look forward to hearing from you!
