How to test your MVP in 2 hours
A practical, prioritized 2-hour testing playbook for solo founders and small teams shipping their first version.
What clients say
Founders and engineering teams I've worked with recently.
“Emre's attention to detail is unmatched. He found a critical bug in our payment flow that our team had missed for weeks. Highly recommended for any startup shipping fast.”
“We hired Emre for a one-time QA audit before our seed round demo. He delivered a clear report in 3 days and even flagged issues in our onboarding UX. Worth every dollar.”
“Working with Testopius was refreshing — async, professional, and the automation setup he built for us cut our regression time from a full day to 20 minutes.”
Client names anonymized under NDA. Verified LinkedIn references shared privately on request — usually within 24 hours.
