Employment
Experience
- Search Engine for Croatian Legal Documents
A Django and Apache Solr web application.
I was the lead developer on this project and proposed the system's architecture as a set of microservices. The documents were stored and indexed in Solr, whereas the Django front end served requests and communicated with Solr. - Retail Sale Forecasting
The project was to design a model to predict sale amounts based on historical data of orders, previous sales, and regions. The forecasting was done on a regional and global level and acted as a time series prediction matter. I experimented with several time-series prediction techniques such as ARIMA and SARIMA models.
