selyne

selyne is a full-stack crm for freelancers and small creative agencies. it brings client management, projects, tasks, deadlines, and sales opportunities into one place.

i designed and developed the application across the frontend and backend.

• designed the main workflows for managing clients, projects, tasks, deadlines, and sales opportunities
• implemented authentication and protected application workflows
• created relational data models with prisma and postgresql
• connected the database to the application’s client and project management features
• built responsive interfaces with react, tailwind css, and shadcn/ui
• deployed the application through vercel

selyne helped me understand how separate business workflows connect together inside one application. it also gave me practical experience working with authentication, relational data, and product structure beyond individual pages.

• next.js
• react
• typescript
• tailwind css
