Ioana Vasiliu

I help companies build reliable backend systems, APIs, integrations, and AI-powered automations using TypeScript, Node.js, NestJS, AWS, Azure, and OpenAI/LLM technologies.

I have 7+ years of experience as a Backend Engineer and Technical Lead, with strong expertise in scalable backend architecture, microservices, serverless systems, REST APIs, databases, and cloud-native applications.

I can help with:

• Node.js / NestJS backend development

• API design and third-party integrations

• AI agents and LLM-powered workflows

• OpenAI / Azure OpenAI integrations

• Backend refactoring and performance improvements

• Cloud-based systems using AWS and Azure

• Technical leadership, code reviews, and architecture guidance

I’m especially interested in projects where backend engineering meets automation: customer support agents, internal tools, SaaS backends, data workflows, and intelligent business processes.
