About this gig
Struggling with slow, buggy backends holding back your app?
I'm a Senior Full-Stack JavaScript engineer specializing in Node.js backend development, API architecture, and headless CMS integrations for startups, agencies, and SaaS products. I build secure, scalable, and well-documented backends that perform reliably in real-world environments.
What I can do for you:
- ️ Custom REST & GraphQL API development (Express, Next.js, NestJS, Hapi, Koa, Sails, Hono)
- Database setup (MongoDB, PostgreSQL, MySQL, MariaDB, Redis, Prisma ORM)
- ️ Headless CMS integrations (Strapi, Sanity, Contentful, Directus, custom CMS)
- ️ Integrations (Stripe, OpenAI AI, AWS/GCP cloud)
- ️ Microservices, MVC & legacy SOAP integrations
- ️ Real-time APIs (WebSockets / Socket.io)
What you get:
- Clean, scalable architecture
- Secure authentication (JWT, OAuth 2.0, RBAC, rate-limiting)
- Optimized performance & database design
- Clear API documentation (Swagger / Postman)
- Fast communication & post-delivery support
Whether you're launching an MVP, scaling a SaaS product, or improving an existing API, I deliver production-grade solutions built for growth.
