Montassar A.

I'm Montassar, friends call me Monta. I help startups and growing businesses turn complex operational problems into full-stack applications that are reliable, scalable, and easy for their teams to actually run day-to-day. Full-stack developer based in Monastir, Tunisia, specializing in Angular, NestJS/Node.js, React and PostgreSQL. 5+ years building production systems for clients ranging from a national pharmaceutical distributor to enterprise teams at Lagardère, alongside independent SaaS products I design and ship end-to-end. My Core Services: ✔ Full-Stack Web App Development (Angular, React, NestJS/Node.js) ✔ REST API Design & JWT/Role-Based Access Control ✔ PostgreSQL & Multi-Tenant Database Architecture ✔ Payment Integration (Stripe, Flouci) ✔ SaaS Product Architecture & Data Modeling (Prisma) ✔ Dashboard & Data Visualization (ChartJS, TanStack Query) ✔ Legacy System Migration (e.g. Laravel → Angular) ✔ Third-Party Integrations (Twilio, Yousign, Resend) ✔ Agile Delivery (Scrum, Kanban) I specialize in owning a project from data model to shipped UI, so clients get a system that's actually maintainable instead of a pile of half-integrated tools. Every build is done with an eye toward what the team will need to run and extend it a year from now, not just what looks good in a demo. If you're looking for a developer who can take a business process and turn it into a real working system, I'd be glad to hop on a call.
