Software Development Principles: A Pragmatic Guide

A practical approach to software development based on years of experience

Introduction

This collection represents practical lessons learned from many years of software development. While not claiming exceptional intelligence, these insights come from extensive experience building and maintaining software systems, along with the mistakes that inevitably accompany that journey.

These principles are intended for developers at all levels, but particularly those who value pragmatic solutions over theoretical perfection. Some may find this approach overly simplistic, but experience suggests that simple, maintainable solutions often outperform complex, "elegant" ones.
