About Me

I’m a software engineer with 5+ years of experience building and maintaining large-scale, production systems. My work centers on backend architecture, distributed systems, and improving system performance, and I’m expanding into machine learning, LLMs, and agentic AI.

I also have hands-on exposure to frontend development and IoT systems at a foundational level.

Beyond engineering work, I enjoy reading books, playing guitar, listening to music, writing technical blogs.

Why consistency doesn't belong in ACID

This post challenges the traditional ACID definition by arguing that consistency is not a database guarantee but an application responsibility. It explains ACID properties, real failure scenarios, and shows why only atomicity, isolation, and durability are enforced by databases, while consistency depends on how transactions are designed.
