FAQ
Do you work with existing codebases or only greenfield projects?
Both. I can audit and refactor an existing monolith into microservices, or build a new architecture from scratch. Share your repo in the message and I'll assess it before we start.
What if I need more than 6 microservices?
Send me a message with your requirements. I handle larger scopes through a custom offer — priced based on service count and complexity.
Will I own the full source code?
Yes, 100%. You receive the complete codebase, environment configs, deployment scripts, and documentation. No lock-in.
Can you also build the frontend for my project?
Yes! While this gig focuses on backend architecture, I'm a full-stack engineer and can absolutely handle the frontend too.
