Give two reasons why the Danube Delta is sparsely populated.
Most of the delta is water and marsh, so there is very little solid ground to build on. Villages can only be reached by boat, which keeps them far from jobs and services. That is why so few people live there.

Ingredient lists are hard to read at the shelf, and barcode databases miss many products. The app had to go from a photo or a scan to a clear explanation, without posing as medical advice.

Ștefan managed to be not just a mentor, but a true team member. His advanced technical knowledge helped us develop a functional application in a short time that was appreciated by the jury.
The team quickly understood what I wanted and managed to turn my ideas into a clear, fast, and easy-to-use platform. Communication was efficient, and the final result perfectly reflects the style and needs of my editorial project.
I was looking for transparency and clarity, and that's exactly what I found in my collaboration with Ștefan. I prefer to have the peace of mind that things happen exactly as we agreed, exactly at the time we set together.
The team understood the direction I wanted to go and managed to turn my ideas into a modern and intuitive website. Communication was constant, and the site turned out exactly as I wanted.
The collaboration with CodingShadows, consisting of consulting for our mobile application management, was sensational. The team's experience and professionalism are at the highest level.
