Skills
Web & mobile
I build interfaces with Vue and Nuxt, and work with Angular professionally. I am also developing my React Native and Expo skills through the Manga Hive mobile app.
Back-end & data
I build APIs with NestJS and PostgreSQL, covering authentication, business rules and data management. In Manga Hive, I use Prisma, Redis and BullMQ to connect the catalogue, caching and background processing.
Production & maintenance
I deploy and maintain Manga Hive on a VPS with Coolify, keeping preview and production environments separate. I also handle image optimisation and storage on Cloudflare R2, as well as fixes and product improvements.
