Saad S.

I help startups and businesses build reliable backend systems that are designed to scale from day one. My focus is on Node.js API development, AWS cloud infrastructure, and AI/LLM integrations that turn product ideas into production-ready systems. I build REST and GraphQL APIs, microservices, authentication flows, automation tools, and third-party integrations for SaaS products and internal platforms. I also work with OpenAI, Claude, and Gemini APIs to add AI features such as chatbots, workflow automation, content generation, and intelligent assistants. On the infrastructure side, I use AWS services like EC2, Lambda, S3, VPC, CloudFront, and Elastic Beanstalk to create secure, maintainable, and high-performance deployments. I also work with MongoDB, PostgreSQL, MySQL, Stripe, Twilio, WebSockets, and Socket IO when a project needs real-time or payment-driven functionality. If you need a backend engineer who can build clean APIs, integrate AI features, and deploy scalable cloud solutions, I’d be happy to help. Send me a message and let’s talk about your project.
