Things I learned from working remotely as a software developer

Unexpectedly, during the past weeks, remote work became a thing.

If you didn’t notice this remote work trend recently, take a look at that Google Trends data:

Probably this is not how remote revolution was supposed to look like.

REST API with Spring Boot and MongoDB using Kotlin

If you think about Kotlin you could probably think about Android and mobile development.
It’s true. When Google announced Kotlin as the preferred language for the Android platform, its overall popularity increased sharply.

According to The State of Developer Ecosystem 2019, the survey made by JetBrains (Kotlin language creators), 62% of Kotlin-based apps were mobile. But 41% of Kotlin projects were related to web back-end development.

Indeed, Kotlin may be a good choice for server-side development. Among other frameworks, Kotlin is one of the officially supported languages of the Spring Framework.

In this text, I’d like to show you how easy it is to create a Spring application using Kotlin. I’m going to implement a simple CRUD REST API with Spring Boot and MongoDB as a database using Kotlin as a language.

So, get started with implementation and try it yourself.

Angular 8 with Leaflet map – geocoding using Nominatim API

Geocoding is the term used to describe the proccess of exchanging address into corresponding geographical data (coordinates).

If you’re looking for out-of-the-box geocoding services there are plenty of them. For example, you can consider the most popular one – Google Maps Geocoding API which is pretty good but it’s not really free to use.

There’s a different solution, especially if you’re using OpenStreetMaps-related maps engine. It’s called Nominatim and basically it’s the OSM searching engine with open web API.
