KafkaIQ
A live subscription app for learning Apache Kafka – quizzes, a 175-module course, a visual architecture designer and AI-powered architecture reviews.
The challenge
Engineers preparing for Kafka interviews or designing real systems had to piece together docs, courses and diagrams from different places, with no way to check whether their architecture would actually work.
What we built
A full-stack SaaS platform: 146 quizzes across 11 topics with timers and explanations, a 175-module structured course, an analytics dashboard, a drag-and-drop Kafka topology designer and GPT-4o analysis that reviews your architecture and answers questions about it. Built with React and Spring Boot, with sign-in and paid plans.
The result
A live product with free and paid tiers at kafkaiq.com – designed, built and run end to end, from the database and API to payments, AI features and the marketing site.

Μπαίνεις ξένος.Βγαίνεις ντόπιος.
Την πρώτη φορά σε ρωτάμε τι πίνεις. Τη δεύτερη, το ξέρουμε.
Ξεκινάμεαπό τα βασικά.
Φρέσκος κόκκος, αλεσμένος τη στιγμή που παραγγέλνεις. Ούτε από πριν, ούτε «περίπου».
Λίγη υπομονήκάνει τη διαφορά.
Ζεσταμένο όσο ακριβώς χρειάζεται, για να μείνει γλυκό και βελούδινο. Το σχέδιο από πάνω είναι κέρασμα.
Κάτσε.Δεν βιαζόμαστε.
Ο καφές σου είναι έτοιμος, η καρέκλα επίσης. Την επόμενη φορά θα ξέρουμε και το όνομά σου.
