Hi, Im a Backend / Full-Stack Developer with strong experience in Node.js and AWS, and Im very interested in this long-term cooperation opportunity. In my current role, I work daily with server-side application development, designing and maintaining RESTful APIs or Graphql, handling authentication, business logic, and database integration. Im comfortable taking ownership of backend systems from architecture to debugging and optimization. This is how I match your requirements: -> Node.js & Express.js Ive built and maintained backend services using Node.js with Express, focusing on clean architecture, reusable modules, and maintainable code. -> Database Architecture Experience working with MySQL and PostgreSQL, including schema design, query optimization, and data integrity. Im also familiar with MongoDB for non-relational use cases. (I also able to use Elasticsearch or DynamoDB for NoSQL) -> Cloud & Scalability (AWS) Hands-on experience deploying and managing applications on AWS (EC2, RDS, S3, IAM). I understand how to design backend systems with scalability, security, and performance in mind. -> Debugging & Performance Optimization I independently troubleshoot backend issues, analyze root causes, and improve performance through better queries, caching strategies, and efficient logic. -> Code Quality & Collaboration I write clean, well-documented code, participate in code reviews, and communicate clearly with team members. Im comfortable working independently and meeting deadlines in remote environments. What you can expect from me: 1. Reliable long-term availability 2. Clear communication and proactive updates 3. Production-ready backend solutions 4. A developer who thinks beyond just making it work Id be happy to discuss your current backend architecture and how I can contribute to improving and scaling it long-term. Looking forward to your response. Best regards, Rafly
