You will get a serverless REST API on GCP with Cloud Function endpoints, built using IaC
Project details
I design and build scalable, secure, serverless REST APIs on Google Cloud Platform (GCP) using cloud-native architecture and Infrastructure as Code (IaC).
My solutions leverage Google Cloud API Gateway and Cloud Functions to deliver highly scalable, cost-effective APIs. 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 and governance
• Google Cloud API Gateway and Cloud Functions integration
• Cloud Firestore integration
• Cloud Logging, Monitoring, and observability
Supported authentication:
• API Keys
• JWT Authentication
• OAuth 2.0 / OpenID Connect
• IAM-based authorization
Supported runtimes:
• Node.js (JavaScript/TypeScript)
• Python
Infrastructure as Code:
• 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 Google Cloud solutions that scale with your business.

About Stefan
Senior Software Engineer | Bluetooth LE, IoT, Java & Cloud
Berlin, Germany - 11:11 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.
