EXPERIENCE

Engineered backend architectures for **4 production-grade projects** — Ratela, Dagit, Incheon Heroes, and Voice Korea — using **Axum (Rust)** with clean REST and WebSocket interfaces integrated into Dioxus frontends.

• Implemented complex relational data models with **PostgreSQL libraries** to handle **multi-tenant workflows** and **property hierarchies**.
• Integrated **AWS (S3, RDS, Lambda, CloudFront)** ensuring **scalable deployments with minimal latency**.
• Integrated **Kaia Wallet** into Incheon Heroes for **secure blockchain identity verification**.
• Designed **graph-based backend algorithms** for dynamic content models in Ratela’s pipelines.
• Developed modular **APIs in Axum**, maintaining data integrity and reusable business logic.
• Built **backend test suites** (Playwright + custom benchmarking) ensuring responsiveness under high concurrency.
• Orchestrated **CI/CD pipelines (GitHub Actions)** with **85%+ success rate** across environments.
