🚀 Software Engineer | 📱 Android & Cloud Developer | 🌍 Tech for Impact Builder

I design and engineer scalable, intelligent software systems that blend mobile-first architectures, cloud-native services, and AI-driven insights to solve real-world problems.

My expertise lies in taking ideas from concept → architecture → production, building solutions that are reliable, performant, and human-centric. I focus on creating experiences where technology anticipates user needs, augments decision-making, and drives measurable impact.

I’m passionate about applying technology to:

🌱 Climate & Agriculture – AI-powered tools for sustainable farming and environmental management 📊 Data-driven systems – leveraging machine learning and analytics to transform data into actionable insights 🏛️ Civic & community technology – empowering people with intelligent, accessible, and transparent platforms

I don’t just code — I build systems that think, learn, and serve people effectivel systems that people depend on.
