Go Developer specialized in Cloud-Native technologies
Hi, I'm Andrea — a backend-focused software engineer with a passion for building distributed systems, enabling multi-cloud infrastructure, and exploring how AI can be made accessible and scalable through thoughtful engineering.
I specialize in GoLang, but I've always believed that versatility across the stack is a superpower. My early days with JavaScript gave me the foundation to architect full-stack solutions, and today I use that breadth to deliver robust backend systems with clean architecture, observability, and developer-first design.
At VMware, I've contributed heavily to the Cloud Service Broker (CSB) and its Terraform-based extensions, powering multi-cloud service provisioning across AWS, Azure, and GCP. I'm also a core developer on the GenAI initiative, helping integrate model-serving frameworks like Ollama and vLLM into secure, air-gapped environments for LLM deployment — even in cost-sensitive, GPU-free infrastructures.
You'll find me actively contributing to open source:
- •cloud-service-broker(main contributor)
- •terraform-provider-csbsqlserver(main contributor)
- •csb-brokerpak-aws(main contributor)
- •My own clean architecture and distributed systems experiments
This site is my digital notebook — where I share what I'm learning, building, and breaking.
Let's connect if you're building distributed platforms, tinkering with LLM infra, or just obsessed with elegant code.
Experience
Golang Developer | Cloud Service Broker & AI Infrastructure
Cloud-native platforms | Multi-cloud service provisioning | AI/ML model infrastructure | Tanzu | Cloud Foundry
🔹 Cloud Service Broker & Multi-Cloud Enablement
- Contributed to the Cloud Service Broker (CSB) core powering VMware Tanzu Application Service, enabling cloud-agnostic provisioning of AWS, Azure, and GCP services via the OSB API.
- Developed Terraform-based provisioning flows for RDS, Redis, Object Storage, Aurora, S3, SQS, and Google Cloud SQL.
- Core developer transitioning CSB from Cloud Foundry app-based deployment to a virtual-machine-based architecture supporting zero-downtime rollouts, horizontal scaling, and isolated VM lifecycles for improved reliability and operational flexibility.
🔹 AI Infrastructure & Large Language Models (LLMs)
- Core developer in the GenAI initiative, focused on integrating AI/ML model infrastructure into Cloud Foundry-based environments, enabling easy deployment of LLMs such as Ollama and vLLM within secure, cloud-native platforms.
- Delivered support for air-gapped AI model deployment, optimizing runtime environments for offline model loading, virtual machine-based inference, and custom Modelfile orchestration to control LLM behavior securely and reproducibly in isolated cloud-native environments.
- Built GPU-aware infrastructure provisioning, enhancing support for NVIDIA-powered workloads, FlashAttention, and quantized model formats (GGUF) within cloud-native environments.
- Enabled low-cost CPU-based infrastructure for running large language models (LLMs) in Cloud Foundry environments, helping teams experiment with AI without requiring expensive GPU resources. This approach reduced barriers to entry and supported cost-effective research and adoption of AI technologies within budget-constrained organizations.
