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.
Architecture review, code review and problem-solving consulting.
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).
Short call or screen share to scope the problem, then I dig in and give you a concrete answer. Hourly rate €100.
Hourly. Most consultations are 1-3 hours.
For focused problems — architecture decisions, hard-to-debug issues, or a review before launch — consulting is cheaper and faster than a hire.
