Evidence-Based Engineering: How Research Shapes My Full Stack Development Process

Many developers focus on shipping features fast, but speed without structure often leads to technical debt.

I’ve been exploring an approach I call Evidence-Based Engineering
It’s about:

Measuring performance instead of guessing
Designing modular, testable systems
Documenting everything like a research process
Learning continuously from academic findings

This mindset helps me build software that’s not just fast, but sustainable and data-backed.

Do you use research or data-driven approaches in your dev workflow?

Understanding Caching in Web Development

Caching plays a crucial role in improving performance and reducing latency in modern applications.
From CPUs to CDNs, caching is everywhere, and understanding how to use it effectively can make a huge difference in your system’s scalability.

In this post, I explore:
Cache-Aside (Lazy Loading): Fetch from DB on a miss, then store in cache.
Write-Through: Update DB and cache simultaneously for strong consistency.
Write-Behind: Write to cache first, update DB asynchronously for speed.

Each pattern comes with its own trade-offs between performance, consistency, and complexity, and choosing the right one depends on your use case.

Always remember: your database is the source of truth, and your cache is the performance booster.
