"It's just a simple query". Why the distance between a logical requirement and its infrastructure cost is the most expensive gap in engineering.

Two years of coding with AI every day: what actually saves time, what creates hidden debt, and why your fundamentals are your only real defense against hallucinated correctness.

CouchLens is a browser-based tool for analyzing Couchbase N1QL query performance. It parses system tables, extracts execution plans, and generates insights to help database administrators find performance bottlenecks without sending data to external servers. This post explains what it does, how to use it, and what features are coming.

Working with Couchbase for the past year and a half has been more than just learning a database. It has been an exercise in system thinking: seeing how indexes, queries, consistency, and durability interact, and how small design choices ripple through performance and reliability. This essay is my personal notebook from that journey. It is technically dense because Couchbase demands precision, but it is also reflective because the lessons extend beyond one database. Understanding how array indexes multiply entries, why compound index order matters, or how query consistency flags change latency is not just about Couchbase, it is about learning to think in terms of systems, trade‑offs, and consequences.

Understanding different types of software testing is crucial for delivering a reliable application. Smoke Testing checks basic stability after a new build, while Sanity Testing verifies specific bug fixes or minor updates. Functional Testing ensures that features work as expected based on business requirements. Regression Testing prevents new changes from breaking existing functionality. End-to-End (E2E) Testing simulates real-world user workflows, and Performance Testing checks system speed, load handling capacity, and responsiveness. Implementing these (some or all) test types helps maintain software quality and prevent critical failures.

In engineering, progress is key. However, sometimes teams get stuck in endless discussions, over-planning, and constant changes, delaying actual work. This situation is called "Analysis Paralysis." It happens when people focus too much on making perfect decisions instead of moving forward with practical solutions.
