Where to verify what we say about ourselves.

Public, checkable sources for the facts on this page.

01The company

Kalenux is a software company based in Istanbul, building its own web and mobile products alongside client work since 2021 [1].

Our founder’s engineering work is public on GitHub [2] and his professional history on LinkedIn [3].

KEY FACTEvery product we list links to a live site, a Google Play listing or a public repository.

02How we write about what we know

We publish technical articles on SEO and engineering, mirrored on DEV Community [4] and announced on Bluesky [5], so our claims about methods can be read and challenged in public.
