TypeScript is not just JavaScript with types. It is a design tool that encodes business rules, prevents impossible states, and documents intent — if you use it right.
Every schema change is a risk. Here is the battle-tested playbook for migrating production databases without taking your application offline.
The industry overcorrected. Microservices solve real problems at scale, but most teams are not at that scale — and the complexity tax is killing their velocity.
Most code reviews catch typos and style issues. They miss the bugs that matter. Here is how to restructure reviews around what actually improves code quality.
You cannot improve what you cannot measure. Here is how to build automated evaluation pipelines that catch regressions before your users do.
Retrieval-augmented generation promised to fix hallucinations. It helps, but the harder problems — reasoning, multi-step logic, conflicting sources — need something more.
When should you fine-tune a model versus engineering better prompts? A practical framework based on cost, latency, accuracy, and maintenance burden.
A deep dive into how large language models work under the hood — transformer architecture, attention mechanisms, and the emerging shift toward agentic systems.
