{WebHotelier | primalRES -- Athens, Greece -- Software Engineering Intern}
{
With 9000+ customers in 38 countries, WebHotelier | primalRES stands as the leading travel tech group in Greece and one of the giants in Europe.
\begin{itemize}
\item Spearheaded a complete overhaul of the company's \textbf{Grafana} dashboards, slashing the time-to-load by approximately 80\% while also increasing the number of metrics shown.
\item Collaborated directly with the CTO to secure a year-long contract with \textbf{ClickHouse Cloud} and \textbf{AWS}.
\item Migrated the entire metrics stack from \textbf{InfluxDB} to \textbf{ClickHouse}. This shift amped up performance by over 50\% without inflating operational costs.
\item Engineered an open-source \textbf{Telegraf} ClickHouse plugin optimized for Terabyte-scale data outputs, outperforming the in-built plugin in terms of efficiency.
\item Deployed Telegraf across 12 \textbf{Amazon EC2} instances, a move which unveiled and subsequently led to rectifying several performance bottlenecks.
\item Modernized the logging approach by transitioning to \textbf{ClickHouse}, thereby ending the thread-related challenges of the erstwhile file-based system.
\item Teamed up with fellow developers to incorporate \textbf{DataDog} APM into \textbf{Java} applications, shedding light on intricate application operations and pinpointing areas of enhancement.
