http://thelostexplorertravel.com/ A fancy one-page static website with lots of different parallax animations, a video background, and a video popup. The goal was to convert PSD files into HTML with pixel perfection and launch the website on the live server. A Less-based preprocessor was used for writing clean CSS code. The effects were coded in plain JavaScript ES6 (with no jQuery present). A Grunt task runner performed repetitive jobs and all the source code was pushed into a GitHub repository. It was important to follow best practices for the onsite search engine optimization. The entire website is responsive and ready to use on tablets or mobile devices.

Being the CTO, I was responsible for all sorts of things at Stagelink. In the day-to-day work, I was coding and managing a team, occasionally jumping into server and AWS administration, developing product roadmaps and writing specifications, performing code reviews and one-on-ones with developers, negotiating with designers, and so on. The things that I'm most proud of: • We went through two major redesigns of the website while improving usability, performance, the looks, and user satisfaction. • I successfully moved away from the monolithic Rails app towards an API—cleanly separating the front-end from back-end with some background services performing the heavy lifting (like emails, and so on). • I made the right technical decisions by separating different parts of the product codebase and making them communicate via an API. This saved us from many headaches when scaling-up. • I helped new developers quickly get proficient with Stagelink's code and systems—to decrease the bus factor.
