Oracle & APEX developer | Oracle ACE
Building useful software,
one clear solution at a time.
I'm Alexander Kluev. I write about Oracle APEX, SQL, PL/SQL, SQLcl, Git, CI/CD, generative AI, and whatever useful technology comes next.
Good technical notes begin with a real problem. They explain what mattered, what did not, and why the final solution worked.
That is the aim of this blog: concise articles, useful examples, and practical lessons that can be applied to real work.
