The Challenge
LibLab needed to build a platform that could generate SDKs from API specifications while protecting their proprietary code generation technology. The architecture had to be secure enough to protect intellectual property while performant enough to stream generated code to clients in real-time.
The challenge: design an infrastructure that kept generators server-side while delivering a seamless developer experience.
Our Approach
- Backend Architecture: Built AWS infrastructure using CDK with Docker-based Lambdas and DynamoDB
- Security Model: Architected server-side code generation to protect proprietary generators while streaming output to clients
- CLI Tooling: Built Dart CLI for backend interfacing, simplifying deployment and version management
- Serverless Design: Leveraged Lambda for on-demand code generation without idle costs

Results
The platform delivered secure, scalable SDK generation:
- Protected proprietary code generation technology through server-side architecture
- Enabled real-time streaming of generated code to clients
- Simplified developer workflow through intuitive CLI tooling
- Established infrastructure patterns using modern AWS CDK practices
