01
What we do
Seven areas, one method: read the requirements, design the data and the integrations, build with tests, ship from a pipeline.
-
WordPress development
Custom themes, plugins and editorial tooling built on WordPress core APIs, not page builders.
-
WooCommerce
Stores that stay fast at catalogue scale, with checkout, payments and fulfilment tailored to the business.
-
Enterprise websites
Multi-team, multi-region WordPress platforms with the governance and reliability a large organisation expects.
-
Education platforms
Portals for schools, universities and course providers, with the accessibility and reliability those audiences need.
-
Headless WordPress
WordPress as the content backend for React, Next.js or native front ends, through REST or GraphQL.
-
Performance & security
Measured, not guessed. Profiling, caching strategy, query work and hardening with numbers before and after.
-
Maintenance & support
Ongoing engineering for sites that must stay healthy: updates, monitoring, fixes and small improvements.
-
All services
Deliverables, engagement models and how a project runs from discovery to launch.
02
What we build
Client work is delivered in private repositories, so this is a list of what we build rather than a wall of logos. Ask for relevant examples on a call.
-
01
Enterprise content platforms
Multi-site, multi-language WordPress installations with editorial workflows, role design, deployment pipelines and monitoring for organisations where the website is infrastructure.
-
02
WooCommerce stores
Catalogues, custom checkouts, B2B pricing, subscriptions and fulfilment integrations, engineered to stay fast as products, orders and customers grow.
-
03
Education portals
Course and programme directories, admissions flows, events and student-system integrations for schools and universities, built accessible by default.
-
04
Headless front ends
WordPress as the editorial backend for Next.js or React applications, with clean content APIs, working previews and a caching strategy that survives launch day.
-
05
Custom plugins
Business logic packaged as proper plugins: settings, REST endpoints, background jobs, admin screens and tests, using only public WordPress APIs so updates never break them.
-
06
Integrations
Two-way connections between WordPress and CRMs, ERPs, payment providers and internal systems, with retries, logging and an audit trail.
03
How we engineer
The same standards on every project. The first three are published on our GitHub profile; the rest follow from them.
-
01
One project structure
Every project starts from the same repository layout, tooling and conventions. Onboarding an engineer takes hours, not weeks, and nothing depends on one person's memory.
-
02
Tested, automatically
Unit and integration tests for the code we write, end-to-end tests for the flows that matter, all running in CI. Regressions are caught by a pipeline, not by a client.
-
03
Coding standards enforced
WordPress Coding Standards, static analysis and code review on every change. It is slower on day one and much faster by month six.
-
04
Performance by measurement
We profile before we optimise and we ship with numbers. Caching, query design and asset strategy are decided from data, not from a plugin's marketing page.
-
05
Secure by default
Least privilege, hardened configuration, dependency updates and a plan for incidents. Security is part of the definition of done, not a separate quote.
-
06
Built to be maintained
Public WordPress APIs only, documented decisions, reproducible environments. The next team (or the next version of us) can pick it up without archaeology.
04
What clients say
Public reviews of our founder's work on Codeable, where he is a Certified Expert. 4.96 average across 273 reviews.
-
We are in very different time zones which meant we were often communicating at different times of the day, but Valerii replied to enquiries very promptly and always gave clear detail in his explanations. I would definitely recommend him to other users.
-
The work was carried out exactly as requested. Valeriy was clear about the task in hand and provided a detailed explanation of the what changes were made and where they were made for future reference.
-
Valerii was great at responding back on the problem and had found initial problems even before being hired. Understood the task and executed with great confidence.
06
Writing
Notes on WordPress and WooCommerce engineering, written from project work.
-
One project structure for every WordPress build
How we lay out a WordPress repository so that coding standards, unit tests and end-to-end tests run on every change, and why the same structure on every project is the real productivity win.
-
Where the time goes in a slow WooCommerce store
A profiling-first tour of the usual suspects in WooCommerce performance: the post meta model, cart fragments, uncached sessions, the checkout, and the plugins that touch every request. With the fixes that work and the ones that only look like they do.
