What is MVC? M → Model It is a design pattern used to organize your code by separating concerns. => In Spring Boot, MVC helps structure web applications cleanly. MVC in Spring Boot is a design pattern that separates an application into Model, View, and Controller. The Model handles data and business logic, while the View is responsible for displaying the user interface. The Controller acts as a b
Skip the theory rabbit holes. This is the caching knowledge that shows up in system design interviews, code reviews, and the 2 AM production incidents nobody warned you about. Why Caching — The 30-Second Version Where Do You Actually Cache?

Building a Translation Pipeline for International Contract Bidding If your company bids on international contracts, you've probably dealt with the translation bottleneck. Technical proposals need precise translation, certified documents have strict formatting requirements, and procurement deadlines don't wait for anyone. After seeing how UK public procurement translation requirements can make or
Inside the five-stage pipeline from 1.1.1, there is another fork right after the parser. PostgreSQL classifies every SQL command into one of two camps. One side holds the optimizable queries, the other holds the utility commands. The classification is decided by a single field on the Query node, commandType, and from that point on the two camps travel completely different paths. One goes through t
Go is a compiled language — the code is converted into machine‑readable form before execution. From a beginner’s perspective, this means Go catches many errors during compilation, giving you cleaner, faster, and more predictable performance at runtime. Go is widely used for: API development CLI tools Microservices architecture Backend server. DEVOPS activity So it fits perfectly with the kind of
Why I built it I needed a PostgreSQL parser that could run inside Go tooling without CGO, external binaries, or runtime dependencies. SQL is not one grammar PostgreSQL has a lot of dialect-specific edge cases AST shape matters more than “can it parse” Error handling becomes a product feature Real-world SQL is uglier than examples No CGO, easy installation, works in CI, easy to embed in linters a
If you've tried building an AI agent in the last six months, you've hit the same wall: there are half a dozen frameworks, each with a different philosophy, a different API surface, and a different definition of what an "agent" even is. I spent a weekend writing the same simple agent — "read a GitHub issue, classify it as bug/feature/question, and post a comment" — in six different frameworks. This
