Senior WordPress / PHP Engineer

Yavor Zagorski / 10+ years in web development

I build it. I keep it running.

I’m Yavor. I build custom WordPress systems, connect the moving parts, and take responsibility for what happens in production.

What I engineer behind it.

Custom blocks.
Structured data.
PHP → published interface.

Approximately five years.Engineering and long-term ownership of one WordPress platform.

The OSB engineering story Contact me
01OSB / Media Hype · Production ownership

Five years inside
one production system.

Not just the visible website. The tools people publish with, the data it depends on, and the responsibility of keeping it running.

Approximately five yearsMultiple theme generations30+ custom Gutenberg blocks
01 / Give editors controlStructure before styling.

Real editor · custom blocks

Custom blocks and editorial workflows turn structured bookmaker and casino content into something editors can actually manage.

02 / Make the system usefulOne model. A usable product.

03 / Keep it working

The page is the surface.
Ownership goes deeper.

Connected data
REST integrations, odds and statistics, structured bookmaker and casino systems.
Commercial & editorial logic
Custom plugins, affiliate / CTA management and publishing workflows.
Production responsibility
Performance, caching / Redis, infrastructure, security, deployment and troubleshooting.

WordPress engineering and long-term ownership

Inside the OSB engineering ↗
02WordPress software / VTX plugins

The solution should
outlive the task.

Reusable PHP software, native WordPress integration, and controls that make the behavior explicit.

VTX Redirect

A changed URL shouldn’t become
an unpredictable production problem.

Inside the plugin ↗
VTX Redirect real WordPress rule-administration interface
The actual plugin workspace · rule administration
Predictable by design.
  1. Normalize the path
  2. Match an enabled rule
  3. Resolve a safe destination

Exact-path matching. Relative-path cycle checks. Explicit query-string handling. A bulk editor for changes that need review.

VTX AI Chat

The engineering problem is the boundary:
what content reaches the provider?

Inside the plugin ↗
VTX AI Chat real WordPress knowledge-base screen with native content index and imported knowledge controls
The actual plugin workspace · knowledge and context
WordPress first. Provider second.
  1. Index selected public content
  2. Retrieve relevant context
  3. Apply scope and request limits

WordPress content synchronization, controlled context, local out-of-scope replies and a separate provider integration. The built-in Free index excludes recognized WooCommerce content; imported knowledge is a separate input.

03Arvelis / Product & systems engineering
arvelis

A business requirement
isn’t a data model.
That’s the work.

People, records, rules and workflows. Arvelis turns an operational requirement into a proposed system, with validation and a human decision before creation.

This is custom software work: making the boundaries explicit, not just generating another interface.

04Interactive engineering / A different register

The same rigor.
Another dimension.

Production engineering is the core.
These projects show how far the interface can go.

Light / space / transitions

Mediterranean light, an architectural frame and a quieter kind of interaction. A private-residence visual concept.

The depth is

Supporting the engineering

Creative frontend makes the system legible. AI accelerates implementation; requirements, architecture, code review, validation and production responsibility stay with me.

Serious remote engineering work.

can own the hard part?

WordPress / PHP. From the first requirement
to the problem that only appears in production.
