How should I split my monolith into services?

Den

Start with a strangler-fig pattern: identify bounded contexts, extract one service at a time starting with the least coupled domain. Focus on data ownership first.

About Me

I am a Senior CTO and technology strategist with 15+ years of experience building software products across AI, FinTech, Web3, MedTech, Cybersecurity, and Renewable Energy. Based in Dubai, I work with founders and executive teams worldwide to turn ambitious ideas into scalable, investor-ready systems.

My approach is hands-on and pragmatic. I do not believe in over-engineering or technology for its own sake. Every decision - from architecture to team structure - is driven by one question: does this help the business win? I have delivered 60+ projects to production and led engineering teams of 50+ people by combining strategic thinking with deep technical execution.
