FAQ
Do you work in both Go and Java?
Yes — Go is my default (faster, smaller footprint, great for microservices). Java Spring Boot is available on request at no extra charge. Just mention your preference when placing the order.
Will I receive the full source code?
Yes. Every package includes full source code, a README with setup instructions, and docker-compose for local development. Standard and Premium packages also include tests.
Can you integrate with my existing infrastructure?
Yes. I work with PostgreSQL, MySQL, Redis, and MongoDB. If you have existing services, share the details in your requirements and I'll integrate with them.
