• Strong familiarity with third-party tools (chat, messaging, storage, content moderation, analytics, notifications, etc.) to speed up MVP development.
• Ability to design both MVP-friendly and long-term scalable architecture.
• Solid background in estimating projects, where you were responsible for both the estimation and the delivery.
