Cover image for Reserved Land & Reserved Forest
Reserved Land & Reserved Forest Map – Pandalur & Nadugani Ranges This project focuses on mapping reserved lands and reserved forests in the Pandalur and Nadugani ranges under the Gudalur Forest Division. Using QGIS, I created a detailed administrative map including division, range, beat, and survey boundaries. I integrated forest classification data with terrain (slope) analysis to provide a clear understanding of land distribution and landscape characteristics. The map also highlights human settlements within and around forest areas, helping in planning, management, and decision-making. This project demonstrates my expertise in administrative mapping, boundary digitization, and geospatial data visualization for government and environmental applications. 👉 Available for administrative mapping and GIS projects. Feel free to message me.

Cover image for Professional GIS Mapping & Asset Digitization Services
Utility Mapping & Asset Digitization using GIS Description Accurate utility mapping is essential for infrastructure planning and asset management. In this project, I developed a comprehensive GIS-based utility map by integrating field-collected GPS data with spatial datasets. I digitized utility assets such as pipelines, electrical lines, and infrastructure features, ensuring proper alignment and georeferencing. Using ArcGIS and QGIS, I organized the data into structured layers, making it easy to analyze, update, and use for decision-making. The final output included clean, high-precision maps and GIS datasets (Shapefile/GeoJSON) that can be used for planning, maintenance, and future expansion of utility networks. This project highlights my ability to handle large datasets, ensure spatial accuracy, and deliver professional GIS solutions for real-world applications. 👉 Available for utility mapping, asset digitization, and GIS data management projects.

Cover image for Human–Wildlife Conflict Map Human–wildlife conflict is
Human–Wildlife Conflict Map Human–wildlife conflict is a major challenge in forest fringe areas. In this project, I analyzed conflict incidents across the Nilgiris landscape to identify high-risk zones and support better decision-making. Using ArcGIS and QGIS, I mapped human death incidents, wildlife presence (leopard, tiger, gaur, wild dog), and hotspot villages. I integrated terrain (slope), forest boundaries, rivers, and reservoirs to understand patterns of wildlife movement and interaction with human settlements. The analysis revealed that most conflict incidents occur near forest edges and buffer zones, especially in villages close to protected areas. Leopard activity was widely distributed, indicating higher interaction risk with human populations.This project demonstrates my ability to transform complex geospatial data into clear, actionable insights for forest management and conservation planning. 👉 Available for similar GIS mapping and spatial analysis projects.

We use satellite imagery to monitor different types of environmental data. The map below shows the NDVI (Normalized Difference Vegetation Index) calculated using Landsat 8 imagery, which indicates vegetation health. You can find more details on this topic in my papers and reports.

Technologies for the carbon market In the map below, hydrograph drainage was generated using satellite imagery (Copernicus Global DSM 30m). The satellite imagery reveals that, in many cases where rivers and springs occur, the required vegetation cover is not properly maintained. With climate change, issues like this are becoming increasingly relevant. The carbon market has great potential for growth and improvement with the use of these technologies.

Market intelligence & AI workflows for CRE and EDC teams
Cover image for Over 3.5 years as Director
Over 3.5 years as Director of Hospitality Analytics at CoStar Group, I authored 140+ market analyses covering hotel performance across 60+ U.S. markets — with a focus on Texas, the U.S. South, and major metros including Dallas, Austin, San Antonio, New Orleans, Nashville, and Atlanta. Work was published at CoStar.com (http://CoStar.com) and syndicated through regional Business Journals and national outlets including the Wall Street Journal. Topics included supply pipeline analysis, demand segmentation, RevPAR forecasting, and emerging market trends — including early calls on extended stay demand driven by infrastructure spending and border city occupancy surges. These analyses were consumed by hotel brand executives, private equity firms, REIT investors, and developers making high-stakes investment and development decisions. Content is owned by CoStar Group. Link directs to my author profile on their platform.

Cover image for Geomorphological Mapping Project | GIS
Geomorphological Mapping Project | GIS Analysis Just wrapped up a geomorphological mapping project for a site located in Pasir Gadung Village, Pandeglang, Banten. This work focuses on identifying landform characteristics and terrain variation to support better spatial understanding and decision-making. In this map, I combined elevation data, contour analysis, and spatial interpretation to classify geomorphological units—highlighting areas dominated by undulating hill formations. The red polygons represent the project activity zones, supported by coordinate points collected from the field. I also included a cross-section (A–B) to visualize terrain changes more clearly, giving a better perspective of slope variation and landform structure across the site. Tools & Approach: - GIS processing and spatial analysis - Contour and elevation modeling - Geomorphological interpretation - Map layout and visualization This kind of analysis is essential for projects related to land development, environmental assessment, and infrastructure planning. Always open to feedback and collaboration—let’s connect 🚀

Cover image for This project aims to design
This project aims to design and develop a modern mobile-based construction and home renovation platform tailored for the Indonesian market. The platform will serve as an integrated ecosystem that connects homeowners with building material suppliers, renovation service providers, contractors, and project monitoring tools within a single digital experience. The product is designed to address common challenges faced by Indonesian homeowners during renovation processes, including difficulty finding trusted contractors, lack of transparency in project progress, fragmented purchasing workflows for construction materials, and limited digital tools for renovation management. The platform combines four core service pillars: Building material marketplace Home renovation and repair services Contractor and worker booking system Renovation project monitoring and documentation The application is intended primarily for non-technical homeowners who require a simple, guided, and trustworthy renovation experience. Therefore, the product strategy emphasizes beginner-friendly navigation, transparent workflows, intuitive mobile interactions, and a modern premium user experience that remains approachable for mass-market users. From a product and UX perspective, this project focuses on creating a startup-grade mobile application blueprint that includes: Product architecture and information hierarchy Mobile UX strategy and interaction design End-to-end user journey planning Marketplace and service booking workflows Renovation project management experience Scalable design system planning Component and navigation structure Screen-by-screen UX documentation Trust-building and accessibility considerations The final output of this project will function as a comprehensive product design foundation for: UI design development in Figma Design system implementation Frontend and mobile application development UX documentation and stakeholder alignment MVP planning and startup execution strategy The visual and interaction direction will adopt a modern startup aesthetic inspired by leading digital platforms such as Tokopedia, Gojek, Stripe, Linear, and Airbnb, combining marketplace usability with clean and elegant mobile-first design principles. This initiative is expected to produce a scalable, production-ready mobile product framework capable of supporting future business growth, service expansion, and digital transformation within Indonesia’s home renovation and construction industry.

Cover image for Fast doesn’t mean good. Most teams
Fast doesn’t mean good. Most teams move fast. Ship fast. Break things faster. But speed isn’t what makes a product last. What matters is: – how accurately it solves the problem – how honest the scope is – how maintainable it stays months after launch That’s the idea behind this identity. A visual tension between speed and precision. Between moving fast — and moving right. Because “fast” is easy to promise. But “right” is something you have to stand by.
