Stack SwiftUI, SwiftData, WidgetKit, Firebase, iOS, watchOS

Weather and mood intelligence for iOS. Log how you feel using six weather-themed moods and surface the correlations between your inner climate and the conditions outside. It features Live Activities for lock screen logging, home screen widgets, an Apple Watch companion, severe weather alerts via push, and shareable monthly and yearly Climate Reports. Mood data stays on device by default with no account required.

About Me


Rooted in computer science, mathematics, and product thinking, my work spans distributed systems, privacy-preserving AI, quantitative finance, and native iOS development. From secure messaging apps and federated learning frameworks to algorithmic trading engines and real-time data pipelines, I specialize in designing end-to-end systems that are both performant and principled.


My engineering is deeply influenced by product thinking, shaped by hands-on experience and formal training in product management, design thinking, and data-driven iteration. I don’t just build systems; I build with context, clarity, and the user in mind.


What drives me isn’t just technology; it’s turning complex problems into simple, elegant tools that empower people.


I’m always excited to hear about bold ideas, ventures in motion, and real-world problems worth solving.


I love open source and believe deeply in the power of shared knowledge. I also write to explore the ideas that move me. You can find my thoughts on Substack and Medium
