Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I’m a Software Engineering graduate with experience building full-stack and AI-driven systems. I’ve worked extensively in the Rust ecosystem (Leptos, Axum, Diesel, Tokio), designing scalable backend architectures, real-time synchronization systems, and production-ready APIs. My background includes building RAG pipelines with hybrid search (dense + sparse retrieval), working with PostgreSQL, Neo4j, Qdrant, Redis, and deploying infrastructure using Docker, CI/CD pipelines, and observability tools. I’m comfortable across the stack (Rust, Go, TypeScript/JavaScript, SQL) and focus on writing clean, maintainable, and scalable systems.…I’m a Software Engineering graduate with experience building full-stack and AI-driven systems.
