I'm a passionate software engineer with over 8 years of experience working as a full-stack developer with a track record of taking large-scale web applications from the drawing board to production.

I have extensive knowledge of front-end JavaScript and browser APIs as well as significant experience with popular frameworks and libraries like React, Vue, and Redux as well as Typescript.

I quickly realized after a few years that the companies I worked with were looking for much more than just an engineer. I figured out that most of my clients wanted someone whom they could trust as a technical partner for their products. Someone, who can give suggestions right from what tech should be picked up, how to get the roadmap right, how should we plan the product launch, and a lot more.

I love to speak with people and help them find the perfect solutions for their problems and help bring their ideas to life. As of today, I always strive to keep the quality high and every request is considered with extraordinary care.
