Database I/O Optimization: 100 Seconds to 3ms
Read ArticleProblem Statement
An application was experiencing severe performance degradation with database queries taking over 100 seconds to complete. This directly impacted user experience and system reliability in production environments.
Target Audience
Backend engineers, database administrators, and technical leads looking to understand query optimization techniques and indexing strategies at scale.
Technical Approach
Analyzed query execution plans, identified missing indexes, implemented multi-level indexing strategies, and documented the entire optimization process. The article walks through the diagnostic methodology, explains the indexing approach, and demonstrates the measurable performance improvements.
Technologies
Outcome & Impact
Reduced query execution time from 100+ seconds to 3ms—a 33x performance improvement. The article serves as a reference guide for engineers facing similar bottlenecks, demonstrating the critical importance of proper database schema design and query planning.
Self-Hosted OAuth2 with Authentik on Vultr
Read ArticleProblem Statement
Organizations needed a self-hosted identity provider alternative to third-party OAuth2 services. Traditional SaaS solutions presented vendor lock-in risks and privacy concerns for enterprises with strict data residency requirements.
Target Audience
DevOps engineers, infrastructure teams, and platform engineers implementing self-hosted authentication systems. Also valuable for security-conscious organizations and those requiring on-premise identity management.
Technical Approach
Created a comprehensive, step-by-step deployment guide using Docker Compose for container orchestration and Authentik as the OAuth2 provider. The guide covers infrastructure setup, configuration, security best practices, and troubleshooting common deployment issues.
Technologies
Outcome & Impact
Published on Vultr's official documentation—demonstrating platform credibility and technical depth. The guide enables organizations to deploy secure, self-hosted authentication with clear, actionable instructions. Serves as a reference for DevOps teams implementing enterprise identity solutions.
Graceful Shutdown Patterns in Node.js
Read ArticleProblem Statement
Node.js applications in production often crash or lose in-flight requests during deployments or server shutdowns. Without proper graceful shutdown handling, data loss and poor user experience occur in critical systems.
Target Audience
Backend engineers, DevOps professionals, and production-focused Node.js developers managing long-running services, microservices, and API servers.
Technical Approach
Provided hands-on implementation patterns for graceful shutdown, including signal handling, connection draining, request completion, and database cleanup. The article explains the theory, demonstrates practical code examples, and covers real-world deployment scenarios.
Technologies
Outcome & Impact
Developers and teams implementing graceful shutdown have a production-ready reference guide. The article reduces deployment-related incidents, improves system stability, and ensures no data loss during restarts. Now a standard reference for Node.js best practices in modern deployment environments.
