A curated collection of small utilities and engineering patterns extracted from web projects I worked on between 2011 and 2021.
The repository contains solutions to practical problems I encountered while building production websites, e-commerce platforms, CRM systems and other web applications.
Each directory is self-contained and includes its own documentation and examples.
A lightweight PHP/MySQL abstraction with typed query placeholders, result helpers, transactions and data transformation utilities.
Client-side date formatting that displays server-side event timestamps in the visitor's local timezone.
Small PHP and JavaScript implementations for selecting the correct Russian word form based on a number.
PHP utility for validating and normalizing Russian and Kazakhstan phone numbers entered in different user-facing formats.
A lightweight heuristic for associating website attribution data with incoming phone calls using click timestamps.
These utilities were originally developed for real production systems rather than as standalone libraries.
The repository preserves a small selection of reusable solutions that are still interesting as examples of practical web engineering from that period.
