The company needed to quickly develop new paperless warehouse solutions for selecting and packaging shipments. I initially created a simulator that highlighted the best processes by comparing different selection procedures.

For the rest of the project, I was focused on developing and delivering the entire system in three cycles using Shape Up product development. It meant starting from the MVP that was used alongside the old solution.

This process enabled a quick launch of the new operational warehouse. In addition, I created helpful tools, including a dashboard and the connection to our partner's path optimization API.

The system was designed to improve the clients' order efficiency and record and organize items before shipping.

It combines different data sources such as client orders, expected deliveries, and stock-or-sale predictions. The final product needs fewer manual interventions because of its semi-automatic features.

I created a simple ebook store that contains a payment gateway connection and an option to deliver books using a web service.

Ordering ebooks is enabled by using an API Gem created in Ruby. This was the first project I developed in Ruby as part of a self-learning initiative.

A Slovak how-to video portal with tens of thousands of page views. I supported the whole network, configured LAMP on virtual servers, and customized the ClipShare tool to meet the client's requirements.

The most challenging part was staying within the budget, and I had to create strong cache to save server resources. Helped by a flexible purge system and strong cache, the homepage and landing pages' response time was under ten milliseconds on a single low-cost Apache server.

In addition, hundreds of videos were connected to the YouTube API, and the new unlisted videos were being regularly uploaded to reduce video hosting costs.
