Web developer with 7+ years of hands-on experience. I write code myself — hand-coding layouts
from Figma and PSD mockups, porting ready templates onto WordPress and Joomla, and building
custom PHP back ends, including in-house admin panels and employee databases for companies.
Comfortable across WordPress, OpenCart, Joomla, custom PHP and React. Delivered projects for
clients in the UK, Saudi Arabia and Ukraine, from single corporate sites to portfolios of 300+ pages
under active maintenance. Background as a materials-science engineer and published researcher —
which shows up as analytical rigour, methodical debugging and a habit of measuring results rather
than guessing. Fluent English and currently looking for a developer role in the EU.

AI- A S S I S T ED D EV E LO P M E NT & PR O M PT E NGI NE ER ING

I write and own my code — layouts, PHP back ends and admin panels are built by me. Claude, ChatGPT and Google Gemini sit on
top of that workflow as a review and acceleration layer, not a substitute for it:
– Code editing and refactoring: implementing site changes, cleaning up legacy templates and reviewing pull-request-level diffs with AI
assistance.
– Debugging: reproducing, isolating and fixing front-end and PHP errors far faster than by manual tracing alone.
– Security hardening: reviewing code and configuration for common vulnerabilities, tightening permissions and closing attack vectors
on client sites.
– Prompt engineering: writing structured, reusable prompts for recurring tasks — code review, content generation, technical
documentation and QA checklists.
– Comfortable evaluating AI output critically: verifying suggestions against documentation before anything ships to production.
