@arpankumarkoley

Data analyst at SOS Engineering Limited who automated powerplant document review, cutting the workflow time by 6 times.

At SOS Engineering Limited, I turned a 326-page powerplant construction document into a one-page interactive spreadsheet using Python, VBA, and Excel Macros, accelerating review by 6 times. I also built Python reliability simulation tools that replaced licensed software and eliminated $50k in annual licensing costs.

At Hydro International Limited, I designed and built a conductivity-based stormwater monitoring system and analyzed sensor data to inform calibration and design. My work also includes numerical analysis and statistical verification for a tuned mass damper design that reduced vibrational response by 8 times.
