Plugins, platforms and small apps. Some are for sale, some are case studies of work I've done — every one of them runs in production.
A WordPress plugin that turns a fragile form-to-external-API integration into a fault-tolerant queue: WP-Cron retries, per-file uploads, full admin logging.
A WordPress plugin exposing a token-secured REST API and a real-time webhook so a companion mobile app stays in sync with the CMS, with full delivery debugging.
A donation-funded e-learning platform for a large non-profit: rebuilt LearnPress templates, custom course access, online & offline courses, bilingual UI.
A custom WordPress plugin that registered 1000+ guests for a large offline event: tickets, phone login, email OTP, per-city transfer seat limits, CSV export.
A 150 KB Mac menu bar app that plays a sound when your battery reaches the charge level you pick. Plain Swift, no Electron, no network code.
Ongoing development of a major charity's WordPress platform: story-driven content types, donation flows, campaign subsites and bilingual templates.

A WordPress plugin that turns spreadsheets into hundreds of SEO landing pages: CPTs, custom fields, AIOSEO meta, schema and images — with a preview step.
A small WordPress plugin that exports WPML translations from staging as a ready-to-import SQL file — no more redoing translations on production.
A custom WordPress plugin that lets shoppers pay in installments via a Ukrainian bank's merchant API — phone validation, signed requests, and full order lifecycle.

Building a multilingual marketing agency site on Elementor with a full modular SEO stack — structured data, E-E-A-T, IndexNow, and precise hreflang.
