Hi, I'm Sajadur Rahman, a dedicated Software Developer with international remote experience, skilled in designing cloud-based solutions with Docker and developing robust backend services using Node.js, Express.js, and NestJS.

I write clean, efficient TypeScript and Go code, build RAG-powered AI solutions using semantic embeddings and vector search (pgvector), and develop scalable ERP, e-commerce, and SaaS platforms equipped with secure payment gateways.

My focus is always on engineering scalable, maintainable architectures that deliver seamless user experiences. Whether optimizing distributed database queries, orchestrating microservices with RabbitMQ, or automating CI/CD pipelines on AWS and VPS environments, I bring engineering rigor and passion to every project.
