I'm a seasoned DevOps Engineer and Software Architect with a deep passion for automation, system performance, and building robust, scalable infrastructure. My journey has taken me from hands-on programming to designing and maintaining complex cloud environments. I thrive on solving challenging problems, from optimizing CI/CD pipelines to architecting high-availability systems.
- 🔭 Architect & Lead Developer of SpinelDB, a high-performance in-memory database with an intelligent caching engine, built from the ground up in Rust.
- ⚙️ Automation is my mantra: I love architecting and implementing seamless CI/CD pipelines using GitLab CI, GitHub Actions, and etc.
- ☁️ Cloud & Infrastructure: Proficient in managing cloud infrastructure on platforms like GCP and AWS, including Kubernetes, networking (VPC, Firewall), and database administration.
- 🤝 Open to Collaboration: I'm actively looking for exciting opportunities as a DevOps Engineer, SRE, or Backend/Systems Engineer, especially in roles involving Rust, Go, or high-performance systems.
- 💬 Feel free to ask me about DevOps best practices, system architecture, Rust, and automation!
SpinelDB is my flagship project—a testament to my passion for building high-performance, resilient systems. It's a modern in-memory database inspired by Redis, but with a unique Intelligent Caching Engine.
Key Features & Concepts Demonstrated:
- Asynchronous & Multi-threaded Architecture: Built with Tokio for highly concurrent network I/O.
- Advanced Caching Strategies: Implements cache stampede protection (request coalescing), stale-while-revalidate, and on-disk streaming for large objects.
- High Availability: Features a Warden process (inspired by Redis Sentinel) for automated failover, leader election, and split-brain prevention.
- Robust Persistence: Supports both AOF (Append-Only File) and snapshotting (SPLDB) persistence mechanisms.
- Security: Includes a detailed Access Control List (ACL) system and SSRF protection.
