Currently

Focus Details
Building macOS apps & LLM triage pipelines at Apple
Shipping upstream 50+ merged PRs in 2026 — ragflow · dify · dify-sandbox · dify-official-plugins · ndnd · on pace for 100+ by EOY
Exploring RAGFlow · LangGraph · LangChain · Dify · SigNoz · Helicone · LiteLLM · Ragas · Qdrant · Infinity · Namma Yatri
Research CustomNerd framework (NYU, manuscript in progress) · Job-Matching-Agentic (WSU) · Odyssey / DataFusion cost modelling (Edinburgh)

Where I'm Heading

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

Merged PRs Upstream Projects Repositories

Track Direction
RAG infra Going deeper into infiniflow/ragflow — agent inputs, deepdoc parsing, GMM clustering, retrieval quality edge cases. Likely moving toward plugin/plugin-API surface next.
Agent frameworks Active 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 observability Contributions and forks in langfuse, helicone, neatlogs, signoz. Watching where OTel-native LLM tracing goes next — likely landing eval/feedback primitives.
Vector & AI-native DBs Forking and reading qdrant-client, infinity, ragas. Ragas-style evaluation harnesses for CustomNerd's research outputs.
Protocols & mobility Shipping into named-data/ndnd (security/CRL) and nammayatri (Haskell, open mobility). 5G protocol testing at Apple keeps me close to ASN.1/UICC pain.
Research CustomNerd 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.
