At SEYTÚ / OMNILIFE, I developed and maintained e-commerce catalog features with Laravel, PHP, JavaScript, and MySQL, connecting interface interactions to controllers and queries.
I implemented filters and cart behavior, improved product-page performance and loading, and investigated production issues through assigned tickets while maintaining existing functionality. I collaborated with a team of 3–4 developers using Git workflows and code reviews.
I built Frostiq, a web app for personal libraries, reviews, and progress tracking, with authentication and role-protected administration. I integrated the TMDB, IGDB, and Open Library APIs, using normalization, deduplication, and fault-tolerant concurrent requests to unify searches.
For PenguSpeak, I implemented progressive audio with a thread-safe buffer and session queues for preloading, cancellation, and voice reconnection. I also added automatic fallback from Edge TTS to Azure Speech when Azure is configured, with recovery checks for the primary provider.
