##about

Software Engineer · Back End Engineer · Scrum · Learning Enthusiast

Hi, my name's Yaya. I live in Klaten, Central Java. Currently I work as a fulltime senior backend engineer (remote), using Golang, SQL, MongoDB, Redis, Elasticsearch, some microservice architecture, and message brokers (pub/sub). I'm also familiar with Node.js, and have a little experience with Laravel, CodeIgniter, and Java Spring Boot.

Familiar with microservice architecture, non-structural databases like MongoDB, and queue messaging with NSQ, RabbitMQ, and Kafka. I also keep learning front-end stacks (Vue.js and others).

Very interested in learning everything I can, especially about software engineering.
