Data Structures Developer in Belgrade, Serbia

I developed a back-end API that supported Drag'n'Drop Form Builder for my client customers. The API consisted of various actions and "widgets" that were loaded into React builder.

I integrated MongoDB to serve as cache and failover of external API Data in case that data is not available due to external error/change.

I redesigned the MySQL database from MyISAM to InnoDB to avoid "zombie" data rows by using foreign keys and reduce locks on tables.

I extended SphinxSE in Yii2 to support eagerLoading of MySQL rows related to SphinxSE results.

I actively managed various services on Linux (UbuntuOS), like listener service that is running ImageMagick to automatically convert TIF images to JPG, once the file becomes available and send both to Google Storage.

Also, mailing system that uses external sendgrid API and standard SMTP over TLS that actively composes and send emails to the customers, once emails are gone in the queue.

I managed the document file conversion service that is supposed to send document files to an external service and listen for a response. Once the document conversion is done to a different filetype, the database is updated with new information and files are sent to Google storage.

I introduced templating support to ease programming in Appzio Framework by using XML as a template which reduced code complexity to a minimum and extended reusability.
