What I am building towards

• Backend systems with clear service boundaries, reliable APIs, and practical data models.
• Developer tools that reduce repetitive work and improve engineering workflows.
• Search, crawling, indexing, and automation systems.
• Cloud-ready applications using Docker, CI/CD, Linux, and managed databases.
