You will get a serverless REST API on AWS with Lambda endpoints, built using IaC.


Project details
I design and build scalable, secure, serverless REST APIs on AWS using cloud-native architecture and Infrastructure as Code (IaC).
My solutions are based on Amazon API Gateway, AWS Lambda, and DynamoDB (or other AWS data services as needed). APIs are designed from OpenAPI specifications, which I can also create from scratch.
Services include:
• OpenAPI/Swagger design and documentation
• REST endpoint modeling and validation
• Authentication and authorization design
• API versioning strategy
• AWS API Gateway, Lambda, and DynamoDB integration
• CloudWatch monitoring, logging, and observability
• Rate limiting, throttling, CORS, and performance optimization
Supported authentication:
• API Keys
• Amazon Cognito
• JWT-based Lambda authorizers
• IAM authorization
Supported runtimes:
• Node.js (JavaScript/TypeScript)
• Python
Infrastructure as Code:
• AWS CloudFormation
• Terraform
• Pulumi
Serverless architecture provides automatic scaling, high availability, lower operational overhead, and pay-per-use pricing. I focus on clean architecture, maintainable code, security best practices, and production-ready AWS solutions that scale with your business.

About Stefan
Senior Software Engineer | Bluetooth LE, IoT, Java & Cloud
Berlin, Germany - 4:32 am local time
I am a Senior Software Engineer specializing in Bluetooth Low Energy, IoT platforms, Java/Spring Boot, and modern web applications. My experience spans the entire technology stack, from native iOS and Android applications to backend services, cloud infrastructure, and web frontends.
I have developed commercial BLE solutions, cloud-connected IoT platforms, REST APIs, and enterprise applications using Java, Kotlin, Spring Boot, TypeScript, Node.js, AWS, Docker, and Kubernetes. Whether joining an existing project or building something new, I focus on clean architecture, maintainable code, and practical solutions that scale.
I am also the creator of the Udemy course *Bluetooth Low Energy Development for iOS*, where I teach developers how to build reliable BLE applications using CoreBluetooth.
Core expertise:
- Bluetooth Low Energy (BLE)
- Native iOS & Android development
- Java, Kotlin & Spring Boot
- Node.js & TypeScript
- REST APIs & OpenAPI
- AWS cloud development
- Docker & Kubernetes
- PostgreSQL, MySQL, MongoDB & Elasticsearch
- RabbitMQ & Kafka
- OAuth2, JWT & Spring Security
Why clients hire me:
- End-to-end expertise from Bluetooth devices to cloud backends
- Strong backend, cloud, and mobile development skills
- Author of a Udemy Bluetooth Low Energy course
- Fast onboarding and productive from day one
- Clean, maintainable, production-ready code
- Clear communication and reliable delivery
I enjoy working on technically challenging projects, whether that means developing a BLE-enabled mobile application, designing scalable backend services, or building complete IoT solutions.
