Portfolio
I design and develop Web GIS applications that transform spatial data into interactive, web-based solutions. Using technologies like Python, Django, Leaflet, and PostgreSQL, I’ve built systems for real-time monitoring, location-based recommendations, and geospatial data visualization tailored to both practical applications and research-driven goals.
My background in classical GIS — including spatial analysis, remote sensing, and fuzzy logic — gives me the insight to develop Web GIS applications that solve real-world spatial challenges. My goal is to develop tools that are scalable, easy to use, and genuinely valuable for real users.
