FastStack · web systems architecture and engineering

We solve complex web systems as a whole, not as a collection of technologies

From existing WordPress business logic to standalone web services, APIs, infrastructure and safe deployment. We define system boundaries, risks and the simplest durable path first — then choose the tools.

Discuss a project What we work with

When we are useful

An existing project has become too complex

Years of integrations, custom logic and new interfaces create hidden dependencies. We map the real system and evolve it without an unnecessary full rewrite.

WordPress no longer solves the whole problem

WordPress can remain the CMS and administrative core while we separate APIs, search, interfaces or file services into components with explicit responsibilities.

You need an operational tool, not another website

We design internal applications, catalogs, file services, search and specialized interfaces around the actual workflow instead of a ready-made template.

The problem crosses application and infrastructure boundaries

Performance, caching, deployment, Nginx, PHP, Node and database failures require work across the production stack. We look for the root cause instead of adding another local workaround.

What we work on

Architecture and modernization

We analyze systems, define clear component boundaries, reduce unnecessary dependencies and modernize gradually without rewriting working software for its own sake.

Backend and integrations

PHP, WordPress, WooCommerce, APIs, databases, external services and business logic.

Modern web interfaces

React, Next.js, TypeScript and server rendering where they provide a measurable architectural benefit.

Production and infrastructure

Linux, Nginx, PHP and Node runtimes, databases, caching, permissions, services, deployment and diagnostics.

Search, automation and AI

Search and context services, local and external models, data processing and AI features with controlled sources and explicit boundaries.

Technology is not the starting point

We do not start with the question of which framework to use. We start with the problem, constraints, data, load, failure modes, operating cost and future change.

If the reliable solution belongs inside the existing WordPress system, we keep it there.
If a component blocks the evolution of the core system, we give it a clear boundary and interface.
If a new service creates more complexity than it removes, we do not create it.
Our goal is the least complex system that can remain understandable and operable for years.

Typical problems

Safely evolve a large existing WordPress or WooCommerce project.
Extract functionality from a CMS without breaking the existing system.
Build an internal web application or specialized interface.
Design APIs and interaction between several applications.
Remove architectural causes of performance problems.
Make deployment, caching and production behavior predictable.
Integrate search or AI with real project data.
Understand legacy or third-party code before a significant change.
Reduce technical debt, fallback paths and hidden dependencies.

How we work

Minimal reconnaissance

We collect verifiable facts about the existing system and establish the real scope of the problem.

Cause and risk

We separate root cause from symptoms and evaluate dependencies, reversibility and operational risk.

Smallest durable solution

We choose the change that solves the problem without creating unnecessary architecture or support burden.

Operational verification

We validate not only current behavior, but also updates, failure, recovery, security, load and future evolution.

What the client gets

Not just code or completed tickets. The result is an operable system with understandable boundaries and predictable behavior.

Clear component responsibilities.
Known data ownership and data flow.
Explicit interfaces and system boundaries.
Deployment, updates and recovery without hidden manual rituals.
Known constraints, risks and a system that can be changed later without rediscovery.

Tools follow the problem

The stack is not the product. We use it as a set of tools inside the chosen architecture.

Have a complex existing system or an unusual problem?

If the problem crosses the boundary of one page, plugin or framework, describe the current system and what needs to change. We will establish the real scope first and only then propose a technical solution.
