PROFILE
Adriano Moreira La Selva
Worked on the langchain4j/langchain4j repository, delivering two core features over two months focused on API development and integration testing in Java. Built URL-based PDF input support for the Anthropic API, extending the existing base64 workflow to enable direct PDF ingestion from URLs while maintaining backward compatibility. Implemented new content factories, mapper logic, and comprehensive integration tests, updating documentation and examples to reflect the changes. Also introduced progressive streaming for AI Service tool calls via TokenStream, allowing partial tool call arguments to be consumed as they stream from the LLM, with robust unit testing and provider compatibility across Anthropic and OpenAI.

Jan 1, 2026January 2026: Implemented progressive streaming for AI Service tool calls via TokenStream onPartialToolCall callbacks, enabling consumption of partial tool call arguments as they stream from the LLM. This work exposes onPartialToolCall through the TokenStream API used by AI Services, aligning with existing StreamingChatResponseHandler support and enabling progressive UI updates and streaming-based control. The change includes API changes, tests, and integration work across the AI service stack, with provider compatibility considerations.
