State Machines With XState: Modeling State Logic Cleanly

Maxim Mironjuk - October 24, 2025

State machines model allowed states and transitions explicitly, instead of leaving them to be inferred implicitly from scattered boolean flags. XState brings this concept to JavaScript as a framework-independent library, with states, events, guards and hierarchical statecharts that work equally well in React, Vue or plain JavaScript.

Persistent Data Structures in PHP: Functional Lists with Structural Sharing

Maxim Mironjuk - October 17, 2025

A persistent data structure keeps its old version fully intact after every change and produces a new version instead, without copying the entire content. In PHP 8.4 this principle can be implemented directly with immutable linked lists and structural sharing, with no external library required.

Using Claude for System Design Reviews

Maxim Mironjuk - October 13, 2025

A system design review with Claude does not replace an experienced architect, but it uncovers blind spots before a decision gets cast into code. Teams that systematically walk architecture documents, scalability questions and tradeoffs through Claude find weaknesses earlier and document decisions more clearly than in an informal meeting.

Implementing the Repository Pattern in PHP Without a Framework

Maxim Mironjuk - October 11, 2025

The repository pattern separates domain logic from the concrete data access technology by hiding a collection of domain objects behind a simple interface. Understanding the repository pattern in plain PHP lets you test business logic without touching a real database, and swap the underlying storage technology later without touching the rest of the code.

Hybrid Approaches: Combining SQL Plus a Document Store

Maxim Mironjuk - October 06, 2025

A hybrid architecture keeps transactional core processes in a relational database, while a document store takes over for variable, heavily read use cases. Whoever deliberately plans data splitting, synchronization, and consistency boundaries gets the advantages of both worlds without settling for an unclean compromise.

Seasonal Campaign Theme Overrides with Tailwind CSS

Maxim Mironjuk - October 05, 2025

Christmas colors still lingering in the code in January, or a Black Friday banner somebody has to manually remove: copy pasted adjustments for seasonal campaigns leave behind permanent cleanup work. A dedicated CSS layer with time driven activation solves the problem structurally and tears itself down automatically once the campaign ends.

Custom Properties as an API Contract for Components

Maxim Mironjuk - October 02, 2025

A component that exports custom properties by accident rather than by design creates an invisible coupling between consumers and internal implementation details. Anyone who instead treats custom properties like a real API, with a clear namespace, documented fallbacks and version stability, makes design systems safely extensible across team boundaries.

Building a Notification and Toast Styling System

Maxim Mironjuk - September 19, 2025

A clean toast system shows success, error and warning consistently, disappears on its own after the right amount of time, and stays understandable for screen reader users too. With Tailwind CSS for the variants and Alpine.js for stacking and timers, this becomes a single component reusable across the whole project.
