Stanislav Denysenko
Front-End & WordPress Developer
I've been building things for the web for almost 7 years — from small business sites on WordPress to
complex React/Next.js products. What drives me is writing code that lasts: clean architecture, reusable
components, stable behaviour across environments. I'm comfortable working the full stack of a frontend
project: layout from Figma, custom WordPress themes, React apps with Redux, performance tuning. I tend
to think about the next developer who'll read my code — and try to make their life easier.

Experience
Front-end Developer
Validev, remote (05.2024 - 11.2025)
Led front-end development on Specter — a large-scale Next.js project with complex UI and many
interconnected components; handled architecture decisions and component design.
Built and maintained web applications in React and Next.js for clients across several industries.
Developed custom WordPress sites and Shopify storefronts, including theme customisation and plugin
integration.
Contributed to Vue.js projects where needed, adapting to the existing codebase quickly.

Front-end Developer / Wordpress Developer
Owlab Inc., Poltava (08.2021 - 07.2023)

Stanislav Denysenko 1
 Contributed significantly to Prorab, an e-commerce platform on Next.js: extended product functionality,
fixed long-standing issues, and improved maintainability.
Participated in the redevelopment of owlab.group — built new sections, added interactive components,
and helped modernise the codebase.
Worked with Redux and Redux Saga for state management; wrote reusable UI components used across
multiple projects.
Built custom WordPress themes from Figma designs with ACF, Gravity Forms, WooCommerce and
Elementor.

Front-end Developer
Big Drop Inc., remote (01.2022 - 04.2022)
Developed responsive WordPress front-ends with pixel-precise layout from design specs.
Wrote clean, reusable JS modules using Gulp, Sass, Swiper, and Slick — without frameworks.

Wordpress Developer / HTML Coder
Owlab Inc., Poltava (05.2020 - 08.2021)
Built WordPress websites and implemented page layouts in React as the team moved toward component-
based development.
This is where I transitioned from site-building to writing structured, maintainable front-end code.

Wordpress Developer
White Label Agency, Poltava (10.2019 - 04.2020)
Delivered client websites on WordPress: theme customisation, plugin setup, responsive layout.

Site Admin / Content Manager → Manual QA Engineer
Ekobiz / Owlab Inc., Poltava (02.2018 - 09.2019)
My entry into tech: started by managing and maintaining websites on WordPress and CS Cart — content,
analytics, Google Ads, security. Later moved into QA, writing test scripts and working with dev teams on bug
triage. That background gives me a practical eye for how users actually interact with a product.

bundling — Vite, Webpack, Gulp. Code quality — ESLint, Prettier, Husky. Package managers — npm, yarn,
pnpm. Containerisation — Docker (basics). Browser tooling — Chrome DevTools, Lighthouse (performance

Selected Projects
Flexible WordPress Theme — my own custom WordPress theme built on ACF Pro, which I've been refining
over time and use as a foundation for most client projects. It reflects my approach to WordPress development:
clean structure, reusable components, no unnecessary dependencies.
React Redux Template — a reusable project scaffold I built to avoid reinventing setup boilerplate across React
projects. Includes routing, state management, folder conventions, and common utilities.
Escape City (WordPress + Vue 3) — a team-building event platform where I implemented a complex multi-
step event creation form built in Vue 3, integrated into a WordPress site. The form logic involved multiple
stages, conditional flows, and required careful state management on the frontend.
Specter (Next.js) — a large product with complex component architecture and rich functionality. Required
careful planning of data flow and component boundaries.
Prorab (Next.js e-commerce) — took over mid-development, refactored key sections, added new features,
and significantly improved code quality.
Owlab.group redesign — contributed new components and interactive sections; one of the more visible
pieces of work from my time at Owlab.
