Senior Backend Consulting
A second opinion on an architecture, a code review before a launch, or help unblocking a specific technical problem. I consult on PHP, Go, MySQL, Elasticsearch, Docker and Linux — hands-on, with concrete advice.
What I Can Help With
Architecture review, code review and problem-solving consulting.
Typical Problems
Relevant Experience
10+ years across PHP, Go, MySQL and Elasticsearch. Recent work: Cenoskop (30M+ products, crawling, Elasticsearch), Niftycent (US price intelligence), facha.sk (Go marketplace), AnalyticsForWebsite (traffic metrics).
What Is Included
How It Works
You describe the problem in writing — code, config or metrics if you have them. I dig in and give you a concrete written answer. Hourly rate €100.
From €100/h
For second opinions and focused questions. Most consultations are 1-3 hours — larger problems start with a fixed-fee diagnosis instead.
Frequently Asked Questions
When does consulting beat hiring?
For focused problems — architecture decisions, hard-to-debug issues, or a review before launch — consulting is cheaper and faster than a hire.
