Summary
I am a Geospatial Technologist with 20+ years of experience delivering high-impact solutions across multinational mapping firms, startups, and UAV ventures. My expertise spans end-to-end spatial data workflows—from field acquisition (LiDAR, UAV, photogrammetry) to geospatial analytics, 3D modeling, and software automation.
I have led teams, built flying-wing drones from scratch, and published peer-reviewed research in machine learning, terrain modeling, and remote sensing. I spent my first 20 years growing up in Yogyakarta, my home town, then in 2003 I moved to Jakarta for work. I lived for almost 20 years there, and then I decided to move to Australia for new opportunities and started working in Sydney in 2022.

Education
Master in Geography Universitas Indonesia, Jakarta — June 2019 – August 2022
I took this master’s program while working at PT Tritara Orbit Surya, focusing on remote sensing and modeling of phenomena resulting from interactions between nature and people. I applied various machine learning models, ranging from classical approaches such as Random Forest and Support Vector Machine to deep learning models like Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) to model and predict landuse changes.
Thesis: Spatiotemporal Study of Rice Fields Changes in Indramayu Regency Based on the Application of Deep Learning Algorithms on Sentinel-1 Time Series Data
Bachelor in Geodesy-Geomatics Engineering Universitas Gadjah Mada, Yogyakarta — June 2001 – November 2003
Initially, I applied for Electrical Engineering but was not accepted. Instead, I was admitted to Geodetic Engineering, which I initially found uninteresting. However, as I trained in various surveying methods using optical equipment such as the theodolite and spirit level—and most memorably, those humongous Wild stereoplotters—I got hooked and decided to stay. The advent of digital photogrammetry and remote sensing, and the introduction of civilian applications of GPS sparked my interest even further.
