ABOUT ME
Software Developer
Software Developer

I used to be Ruby on Rails developer, but having been in hiatus for almost three years, I am now working as a Full-Stack JavaScript Developer. My fields of expertise include Meteor, Node.js and RabbitMQ. I also have a solid understanding of React and its lifecycle methods, but I still need improvement in design/CSS implementation work.

During my free time, I tinker with IoT, electronics and recently, with iOS development (Swift and Objective C) and Go programming to expand my horizons.

My present employer used to be a Meteor-shop and we have been received extensive Meteor.js training. Most of our in-house tools were developed with Meteor, and I have a solid understanding of Meteor publications (which I think is the most important part, both security and optimization-wise). I also have a solid understanding of the Mantra architecture for Meteor, including the underlying concepts of container composition and actions.

I have a fair understanding of using RabbitMQ as a messaging queue for distributed systems and microservices. Although my experience with it is limited with the amqp-node, I can design and implement topologies well.

This is more of a hobby of mine than a profession. I am continuously learning and studying electronics and embedded programming on my free time, so I cannot consider myself an expert on this field. If I have already solved or encountered some of the issues you are having, I might be able to help.
