You will get Full Authentication: Email, Google, Facebook and GitHub for Your App


Project details
I design authentication & authorization systems using Node.js, TypeScript & NestJS, ensuring JWT (HTTP-only cookies), OAuth2 & Redis for scalable session management.
To enhance security and usability, I integrate a modern front-end with Next.js, React, and Tailwind CSS, providing a seamless UI/UX for login flows, multi-provider authentication (Google, GitHub, Facebook), and RBAC (role-based access control).
Quality is ensured with Jest & SuperTest, while CI/CD, Docker & Kubernetes optimize deployment and scalability.
With this approach, I deliver a fully functional authentication solution, from backend security to frontend user experience, ready for enterprise-grade applications.

About Nerlin
Full-stack Authentication Specialist & Microservices
Chivasso, Italy - 6:20 pm local time
Ciao!
Sono un Backend Developer specializzato in architetture a microservizi e in sistemi di autenticazione sicura.
Il mio stack principale include Node.js NestJS/NextJS/Tailwind css/React, con PostgreSQL/MongoDB e Redis per la gestione dei dati e delle sessioni. Implemento sistemi robusti di autenticazione e autorizzazione usando JWT e OAuth2.0, MFA (2FA), Passport,seguendo sempre le best practices in termini di sicurezza.
Mi concentro molto sulla qualità del codice: uso ESLint, Husky, Joi e Jest per validazioni, linting e test Unitari, automatizzati e test e2e. Questo mi permette di scrivere codice pulito, scalabile e facile da manutenere.
Sono disponibile per collaborazioni sia su progetti già avviati che per sviluppi da zero. Se cerchi affidabilità, chiarezza e orientamento al risultato, sarò felice di contribuire al successo del tuo progetto!
A presto,
Nerlin Makaya Nsimba
