⭐⭐⭐⭐⭐ Experienced Web developer ⭐⭐⭐⭐⭐ Hi, there. I'm Alexander from Russia. I have checked your description carefully. I have 9+ years of experience in Web Development. if you offer me the project, I'll provide you High quality, fast delivery, clean code. Yes, fist I'll reply to your questions. 1. No agencies, I'm an individual developer. 2. I have 6+ years of experience in NodeJS, ExpressJS. Users of Node.js are free from worries of dead-locking the process, since there are no locks. Almost no function in Node.js directly performs I/O, so the process never blocks. I think Because nothing blocks, scalable systems are very reasonable to develop in Node.js. 3. Yes, of course, I have experience in AWS Lambda and AWS Amplify. Well... I'm not sure about the correct definition. My opinion is follows: I think Lambda is an ideal compute service for many application scenarios, as long as we can run our application code using the Lambda standard runtime environment and within the resources that Lambda provides. 4. I have 6+ years of experience in MongoDB, I have been built a web app with DynamoDB in AWS Lambda. 5. Yes, I have been implemented Serverless architecure. I can't explain you anymore because I can't write over 1500 letters. Thanks for your attention. let me know if there is any issue in my description. As for my experience, I am sure 100% high delivery and quality. Looking forward to work on your project. I am ready to start right away. Kind Regards.
