Here are some personal projects I am working on. You can find all of them on my GitHub.
whereisivan - I built this bike tracking app to stream my rides from Android to a Kotlin backend and make them visually trackable on a live map via browser. The project includes an Android app, a backend service, infrastructure automation with Terraform, and a web dashboard written in React. I have also written serveral related posts (part 1, part 2 and part 3) Tech stack: Kotlin, Android, Ktor, Koin, React, Terraform
PersonalPageGen - I created this small Go static site generator to turn Markdown content into a clean personal website, including this one. Currently, popular static site generators are way more complicated than they claim because they are made to support different use cases and not only simple personal websites. This web site uses only HTML and CSS. No cookies, no JavaScript. Tech stack: Go
Vluent - A Java library for writing validation rules as small, named objects you can combine, reuse and test on their own. It has zero dependencies, works standalone, and plugs into Spring Boot and Bean Validation when you want it. It provides a fluent API inspired by Java Streams and is already published on Maven Central. Tech stack: Java
