Andrii L.
Senior Full-Stack & WordPress/JS Engineer | High-Traffic Platforms
I help businesses stabilize, modernize, and scale complex WordPress and WooCommerce platforms — especially when standard plugins, fragile integrations, or temporary fixes are no longer enough. I’m a Senior WordPress Architect and Full-Stack Engineer with 10+ years of experience building production systems. For nearly five years, I led engineering at a global media company, supporting more than 20 international WordPress and Next.js websites serving millions of monthly users. My work sits between hands-on development and technical architecture. I can investigate an existing system, identify the real constraint, design a maintainable solution, and implement it without unnecessarily rebuilding everything. How I can help • Build custom WordPress and WooCommerce plugins • Develop complex API, CRM, SaaS, and data integrations • Diagnose performance, stability, and scaling problems • Modernize legacy themes, plugins, and backend architecture • Design headless WordPress and Next.js systems • Automate imports, migrations, editorial processes, and data workflows • Improve deployment, testing, monitoring, and development processes Relevant project experience • Led engineering across a multilingual network of 20+ high-traffic websites • Migrated approximately 300 GB of WordPress media to a scalable image-processing and storage architecture without service interruption • Built an automated WooCommerce import and AI translation workflow for more than 3,000 products • Delivered performance improvements of up to 70% on content-heavy platforms • Developed custom systems for webhooks, CRM synchronization, editorial automation, access control, reporting, and media management • Modernized WordPress platforms using Next.js, Cloudflare, CDN caching, CI/CD, and structured deployment processes I focus on solutions that remain understandable after launch. That means clear boundaries, documented decisions, appropriate use of WordPress APIs, limited plugin dependency, reliable failure handling, and architecture that another developer can maintain. My core stack includes WordPress, WooCommerce, PHP, JavaScript, TypeScript, React, Next.js, Node.js, MySQL, PostgreSQL, Redis, Cloudflare, AWS, Google Cloud, Docker, and automated testing and deployment tooling. I’m best suited to technically demanding projects such as custom plugin development, platform modernization, performance engineering, complex migrations, difficult integrations, and long-term product development. Send me a description of your current system, the problem you are experiencing, and the outcome you need. I will help determine whether the right solution is a focused fix, a custom plugin, a migration, or a broader architecture improvement.
