the story

Why aidware.

aidware is Aida's Romanian freelance business — a one-engineer studio through which she works remotely with clients, mainly in the legal and real estate space.

Before founding aidware, she spent years in enterprise backend development: Java services at scale, event-driven pipelines with Apache Kafka, and AWS cloud applications built from scratch. More recently her work has centered on AI products — multi-agent applications, LLM integrations and document processing pipelines.

What she enjoys most is owning a product end to end: from the first conversation about the problem, through development, to deployment and everything that keeps it running reliably afterwards.
