Where I'm Heading

Open-source contributions and research directions I'm pushing into over the next 6–12 months.

Merged PRsUpstream ProjectsRepositories

TrackDirection
RAG infraGoing deeper into infiniflow/ragflow — agent inputs, deepdoc parsing, GMM clustering, retrieval quality edge cases. Likely moving toward plugin/plugin-API surface next.
Agent frameworksActive across langgenius/dify, dify-sandbox, dify-official-plugins — seccomp hardening, plugin auth flows, model-provider plumbing. Next: cost-tracing hooks and tenant-isolation edges.
LLM observabilityContributions and forks in langfuse, neatlogs. Watching where OTel-native LLM tracing goes next — likely landing eval/feedback primitives.
Vector & AI-native DBsForking and reading qdrant-client, infinity, ragas. Ragas-style evaluation harnesses for CustomNerd's research outputs.
Protocols & mobilityShipping into named-data/ndnd (security/CRL) and other protocol work. 5G protocol testing at Apple keeps me close to ASN.1/UICC pain.
ResearchCustomNerd paper in progress (NYU, Prof. Dennis Shasha) · Job-Matching-Agentic platform maturing toward WSU submission · Odyssey cost-model work with Edinburgh continuing

On pace for 100+ merged PRs by end of 2026 and 2,500+ annual contributions. Always open to upstream issues, RFCs, and design reviews.
