What I do

Fix and extend existing sites

Bugs, broken layouts, slow pages, hacked installs, plugin conflicts, migrations between hosts and CMSs. WordPress and WooCommerce, custom PHP, Laravel. Most tasks are fixed-price from $100.

Build from a design

Pixel-accurate, responsive front end from Figma, with a WordPress or custom PHP admin behind it. For full projects I work with a designer and deliver the whole site.

Backends and integrations

REST APIs, CRM and ERP sync, Stripe and local payment gateways, Telegram bots, CSV and API imports, parsers, cron jobs, MySQL performance.

Servers and technical SEO

Linux, Apache and Nginx, Docker, SSL automation, email deliverability (SPF, DKIM, DMARC), bot filtering, Core Web Vitals, schema.org, crawl and index audits, AI-search (GEO) readiness.

Selected work

Some sites are in Russian or Spanish. Each case describes what was built; the language of the client's site does not change the engineering.

How I work

  1. You send the task. A link, a description, screenshots or a Figma file. I reply within a few hours with questions, a scope and a fixed price or an hour estimate.
  2. We agree in writing. Chat, email or the platform's messages. I work asynchronously and keep everything documented; no calls needed.
  3. I deliver in steps. Daily progress notes, staging link where it makes sense, clean commented code, no page builders unless you already use one.
  4. Handover and support. Short written notes on what changed and how to maintain it. I stay available for follow-ups.

About

I started building websites in 2006 and ran my own web studio from 2007, delivering corporate sites, online stores, internal tools and integrations for companies from small clinics to Audi Russia and an association of international medical manufacturers. Since 2025 I work independently with clients worldwide and live in Vietnam.

I write code myself, at the PHP and SQL level, not only in admin panels, and I also handle the server side: deployment, SSL, email, backups and performance. That means one person can take a task from "the site is slow" or "we need an integration" to a finished, documented result.

Communication is written: English for tasks and documentation, fast replies in your working hours overlap. Russian is my native language.
