@arkanantaradithya
Data analyst at JokiProyek who builds Python and SQL pipelines and validated analyses of 844,392 store-days and 366,508 race laps.
What I'm looking for
At JokiProyek, I take on client data and analysis work by scoping each request and estimating delivery before I start. I clean and analyse datasets in Python, then deliver the analysis or small model the brief calls for.
For my F1 Race Strategy project, I built a tested Python and SQL pipeline with independent SQL cross-checks, then analysed 366,508 laps to measure pit loss across circuits. My retail forecasting project quantified a 38.8% average sales lift across 844,392 store open-days.
At PT. Badak NGL, I built and tested an RSA login-flow prototype for three internal systems, then handed the source code to the IT team and demoed it. I also presented my first-author CelestX research at ICAICTA 2026, evaluating a text model on Indonesian social media data.
