Yassine Remmani Senior Full-Stack Developer

Let’s talk

About Me

I build reliable, revenue-focused platforms — end to end.

I'm Yassine Remmani, a Senior Full-Stack Developer specialized in Spring Boot (Java), Next.js / React, Docker, and PostgreSQL. Since December 23, 2019 I’ve been building and maintaining production software for Auto Dealers Digital.

I design backend architectures, expose secure REST APIs, build modern dashboards, ship SEO-ready sites, and automate deployments with CI/CD and Docker. I deliver platforms that sales can sell and clients actually use.

What I deliver

Multi-tenant platforms at scale

Clients manage content without engineering help while I keep infra, security, and delivery rock-solid.

PostgreSQL designed for reporting. Backups, migrations, and predictable performance.

Fast time to market

Vertical slices: DB → API → UI → deploy. CI/CD + Docker for safe, repeatable releases.

Sales can launch new clients quickly — the system scales with business needs.
