Full-stack SaaS developer · Next.js, Supabase & AI

SaaS products.
Built for production.

I'm Younes Meskafe. Whether you're starting fresh, scaling an existing codebase, or taking an AI-built app to production, I work like an engineer on your team.

I build and harden SaaS products on Next.js, Supabase and Stripe: multi-tenant data, row-level security, billing, integrations and the AI features inside. Experience at Oracle Cloud Infrastructure and Société Générale.

01 / What I can help with

From prototype
to production.

I work with founders and small teams who need someone to understand the product, make the technical calls, and ship working software.

Take an existing app to production

Built with Lovable, Blink or another AI tool? I review the code, fix what's broken, secure the database access rules, finish missing features, and deploy it properly with a staging environment.

SaaS foundations

Authentication, roles and permissions, multi-tenant data, Stripe subscriptions and webhooks, and third-party integrations.

AI features

Assistants and agents that take real actions through your APIs, answers grounded in your own documents with sources, and document workflows with human review.

How I work

  • For an existing app, I start with a code review and a written list of what to fix, ranked by risk.
  • We agree on the first milestone together.
  • Work arrives in small pull requests, with progress demos and plain-language explanations.
  • Testing, deployment and handover notes are part of the plan.

02 / Selected work

Real products.
Real users.

Apps I've built, rescued, reviewed and taken to production for clients, plus products I run myself.

Pre-launch review

Reviewed an app built in Blink before launch: architecture, pending changes, data access and launch risks.

  • A well-built product: helps executive assistants track delegated tasks and follow up on everything they're waiting on

03 / Engineering background

Big-company rigor.
Startup speed.

Cloud security at Oracle and distributed computing at Société Générale taught me how production systems fail. I bring that discipline to your product.
