Telegram
The fastest way. Go straight to the point — no formalities needed.
Contact
A couple of sentences about your infrastructure and what worries you is enough for me to tell whether I can help. I usually reply the same day.
If Telegram is inconvenient or you need to send a document.
There is no contact form on purpose: a form would collect your data, and this site has no use for it. The links go straight to Telegram and to email, with no intermediate pages counting the clicks. More in data and privacy.
To make the review useful
What to write straight away
What you run
A site, a shop, an app, a bot. One server or several.
What worries you
“It goes down”, “it is slow”, “nobody knows how it works”, “the admin left” — in your own words.
How urgent
Burning right now, or something we can work through calmly. It changes the order of the work.
