High-volume production across branding, packaging, large-format print, merch, and video/photo post-production. Often AI-tool-driven workflow (generative image/audio/video tools).

Continuing to maintain Magento/Adobe Commerce expertise and actively looking to return to eCommerce development full-time.

Worked on a few Adobe Commerce projects using Hyvä, covering the full front-end development cycle - from gathering requirements to implementation, optimization, and production release.

Led front-end development across multiple projects, including third-party API integration, Magento version upgrades, and legacy codebase refactoring for improved performance. Also designed a full production server & CI/CD migration architecture (Nginx, MariaDB, Valkey, OpenSearch, RabbitMQ, Varnish, GitHub Actions zero-downtime deploys) for a client migration — paused before implementation.

Provided expert Magento support, including performance audits, optimization, and complex development solutions.

Designed and built a SCSS-based system supporting 20+ stores, and led a major refactor of the project's custom frontend architecture that cut technical debt by 1000+ files. Created specialized modules extending Magento 2 functionality and improving overall site performance.

Led a team of up to 5 frontend developers — consulting on complex client requirements, running internal knowledge-sharing sessions, and breaking down user stories into actionable tasks. Drove technical direction: built reusable modules and UI kits, refactored outdated solutions for better performance, and challenged team practices to keep pace with Magento standards. Partnered with project manager

Owned full-cycle frontend development and support across multiple projects — from planning through production release — while maintaining documentation and sharing best practices with the team.

Built a custom Magento 2 theme from the Blank theme foundation, plus freelance Magento 2 projects with targeted enhancements and fixes.

Built semantic HTML layouts, added JS/PHP interactivity, and supported SEO strategy (keyword research, competitor analysis) for client campaigns.
