Tech Lead & Full Stack Software Engineer

I am a Full-Stack Engineer with over seven years of experience in IT. I started out as a freelancer developing small web projects and building my expertise. Moving on to more complex tasks, such as online marketplaces and cloud-based tools, I collaborated with a team of analysts, designers, and developers to implement UI and business logic and create efficient applications using JavaScript, React.js, Vue.js, Node.js, PostgreSQL, MongoDB, and AWS.

Platform for marketing team collaboration project

USA company

We created an app that collects all relevant information some businesses may need. For example, you are a real estate business and you need to find people who live in a multi-apartment building in some city, who has more than 2 children and are considering moving to a new bigger house. We can provide that business with such a piece of information with the help of our filters and it can send an offer to potential clients. We created an app where you can buy relevant and refined information that is up to date.
