PROFILE
José Nogueira
Over eight months, contributed to the ocaml/opam-repository by building and evolving core developer tooling and AI infrastructure in OCaml. Delivered multiple Passage CLI and library releases, focusing on type safety, dependency management, and streamlined package structure to improve usability and maintainability for downstream users. Led architectural refactors to modernize build systems and CI/CD workflows, while expanding cross-platform support and enhancing error handling. Developed a provider-agnostic OCaml AI SDK with streaming, telemetry, and prompt caching, integrating Anthropic and OpenAI. Also released ppx_deriving_jsonschema updates, adding runtime primitives and improved serialization. Work emphasized functional programming, robust release management, and scalable system design.

Jun 1, 2026June 2026: Delivered OCaml AI SDK 2026 Release with cross-provider prompt caching (Anthropic and OpenRouter), enhanced metadata handling, and breaking changes to improve type-safety. Implemented per-block cache_control (5m default, with ttl) and integrated caching into high-level APIs and streaming paths. Updated Anthropic and OpenRouter providers to support explicit provider options and cache-control placements; system messages now serialized as array-of-blocks; decoder resilience improved by ignoring unknown fields. Extended provider metadata flow through Stream_part.Finish for better observability without breaking downstream code. Result: lower latency through caching, improved token-usage visibility, and stronger cross-provider consistency for AI prompts.

Apr 1, 2026April 2026 — Delivered OCaml AI SDK v6 across two releases (0.1, 0.2) in ocaml/opam-repository, introducing a type-safe, provider-agnostic AI model abstraction with streaming, retry (exponential backoff), and telemetry. Implemented core SDK features (generate_text, stream_text, Output API, UI message streaming) and a server-side chat handler with tool-approval workflow and stop conditions. Expanded provider ecosystem with Anthropic/OpenAI integrations, including streaming, model catalogs, tool calling, and provider factories. Added Melange bindings for React, examples, and end-to-end demos. Strengthened infra with Dune build, automated opam file generation, new dependencies (re2, uuseg, trace), and tests. This work accelerates AI capabilities for OCaml apps, improves reliability and observability, and provides a scalable, multi-provider integration path for business initiatives.

Jan 1, 2026January 2026: Delivered Release 0.3.2 for ocaml/opam-repository, focusing on dependency cleanup and a package-structure refactor to improve usability and maintainability for developers and downstream users. The update removes deprecated dependencies (devkit, re2) in favor of re, marks ppx-expect as with-test, and ships a cleaner opam packaging layout. This work reduces the dependency footprint, simplifies CI, and establishes a more stable foundation for future library-first usage and downstream adoption. Release details are captured in the commit fc464c2a0efc928b9aa793eed3b45709d8fba45c and accompanying CHANGES.
