About this gig

Looking for a high performance, secure, and scalable backend for your web or mobile app? I will design and deploy a production ready AWS serverless backend using Node.js, Lambda, API Gateway, and modern databases.

What I can build:

  • RESTful and GraphQL APIs with high uptime, logging, and monitoring
  • Serverless microservices with AWS Lambda, API Gateway, and DynamoDB
  • Realtime backends using WebSockets and eventdriven architecture
  • Database design and optimization (DynamoDB, MongoDB, PostgreSQL)
  • CI/CD pipelines and cloud infrastructure on AWS

My expertise:

  • Architected an investing platform backend for 1,000+ users with reliable trading and withdrawals APIs
  • Optimized DynamoDB queries, reducing load times by 20%+ for SaaS platforms
  • Built HIPAAready medical backends with secure data flows and auditability

Tech stack: AWS Lambda, API Gateway, DynamoDB, SNS/SQS, S3, RDS/PostgreSQL, MongoDB, CloudFormation/CDK, Node.js, TypeScript.

Send your requirements and Ill propose a clear backend architecture, delivery plan, and timeline.
