Hi,
I work as a backend developer. I have built the backend code and database from scratch for more than 4 applications.
I Have solid experience in software development and architecture.
I have hands-on experience in java8, Spring Boot, microservices,OAuth Mogo DB and MySQL.
The last project I worked in was involving mostly writing complex queries (doing all the functionalities in the query itself), which makes me confident that I can provide you with queries according to your requirements.
We can have a discussion on the requirements, and also if you want to test my skills we can have a call.
