Projects
- Architected a Kotlin/Spring Boot REST API using Clean Architecture, serving as a high-availability data hub for Native Android and iOS ecosystems.
- Deployed a Dockerized stack with Nginx and PostgreSQL, leveraging Cloudflare Tunnels to establish a Zero-Trust network without exposing public inbound ports.
- Optimized delivery via Hybrid Cloudflare Architecture, implementing Edge Caching and WAF filtering to minimize origin latency and secure stateless JWT sessions.
- Engineered a Jetpack Compose interface with seamless Spring Boot integration via Retrofit.
- Implemented Offline-first sync using Room DB, ensuring data persistence when disconnected from the server.
- Utilized Hilt (DI) to manage network dependencies and lifecycle-aware state propagation.
- Constructed a SwiftUI client achieving full feature parity with the Android ecosystem.
- Integrated SwiftData and Async/Await for high-performance reactive updates from the Spring backend.
- Leveraged Combine for efficient resource fetching and synchronized data modeling.
Grade A*
- Stochastic Modeling: Applied HMMs and PCA for pattern extraction in complex datasets.
- Optimization: Refined transition matrices to enhance predictive accuracy in behavioral modeling.
