Contact me

Here are some of the things I am able to do for your company.

Build modern web applications

I was part of a team developing a web application for presales processes enhancing the data gathering and customer procurement processes. I lead the development of a web application for call center agents to handle customer information, quotes and orders throughout Europe improving the application performance and agent workflow. I created a single page registration process for an e-commerce site boosting the number of registered customers.

Build one-off campaigns and enterprise sites

I created numerous sites and style guides for long living projects. I was part of the core team developing an e-commerce site with 2.7M$ in Black Friday orders.

Analyse frontend performance

I am able to find bottlenecks and suggest improvements. From caching, critical rendering path to thread blocking event handlers and smooth animations. I have created reports and implemented changes in preparation for campaigns to better the loading speed and improve the customer experience.

Resolve bugs

Debugging issues is a big part of development. I have experience debugging production errors and implementing fixes. I was able to solve a seemingly random infinite loop in checkout process quickly using my knowledge of tools available in the browsers.

Share knowledge

I regularly follow web development news, technologies and best practices. I have contributed to the onboarding and mentoring processes, done presentations on web performance to clients and colleagues. and led monthly frontend oriented meetings for developers. I was part of a team preparing and conducting a workshop on building applications with React for Estonian Defence Forces.

This is not an exclusive list, I am always interested in web technologies and enjoy picking them up and can probably do that in your company as well.

As a frontend oriented web developer I mostly work with JavaScript, CSS and HTML, but I have experience with other frontend and backend languages.

Here is my resume.
