[ 01 // ABOUT ]4 MODULES

Building intelligent systems.

Senior Software Engineer with 4+ years at Technosec.io — JupyterLab-based analytics platform and notebook-native LLM tooling. Open-source contributor to JupyterLab and the Jupyter-AI ecosystem.

01

LLM Agents & Tooling

Built Datanout, a notebook-native LLM assistant — a LangChain/LangGraph tool-calling agent with human-in-the-loop approval and a full Model Context Protocol client.

02

Retrieval & Safety

OpenAI vector-store file search, cross-session memory, and an AST-based safety gate that blocks unsafe imports and calls in model-generated code.

03

Full-Stack Development

Python/FastAPI/Tornado backends and React/TypeScript frontends — custom JupyterLab extensions, a React Flow pipeline editor, and real-time WebSocket streaming.

04

Testing & Security

Real-fixture test suites and CI/CD, plus security hardening — HMAC-authenticated boundaries, SSRF/CSRF defense, and per-tenant isolation.

  • ▸Primary author of the platform's JupyterLab frontend extension — custom file browser, a dozen-component React/TypeScript design system, and the core plugin entry point
  • ▸Built Datanout, a notebook-native LLM assistant — LangChain/LangGraph tool-calling agent, human-in-the-loop approval with resumable persisted interrupts, a full Model Context Protocol client, OpenAI vector-store file search, and AST-based code safety
  • ▸Architected a cross-origin notebook ↔ analytics integration across 3 hosting modes, secured by an HMAC-SHA256 authenticated RPC bridge
  • ▸Built a custom React Flow pipeline-graph editor with a two-way ipywidgets/React state-sync layer that prevents echo loops
  • ▸Hardened filesystem, persistence, and lifecycle layers against path-traversal, SSRF, and environment-variable injection; enforced per-tenant session isolation
  • ▸Rebuilt the test suite on real fixtures (~1,000 tests) and decomposed a large coordinator class with zero behavior change
  • ▸Merged contributions to JupyterLab core (shipped in 4.2.0) and the Jupyter-AI agent stack

Datanout — Notebook-Native LLM Assistant

A JupyterLab extension that drops an AI assistant into the notebook and lets it call tools — run cells, edit notebooks, read files, reach external servers — to do real work. Shipped as a Python server extension plus an NPM frontend, auto-discovered via the jupyter_ai.personas entry point.

  • LangChain/LangGraph tool-calling agent with token streaming
  • Human-in-the-loop approval (allow / deny / ask) with SQLite-persisted, resumable interrupts
  • Full Model Context Protocol client — pooling, per-server circuit breaker, SSRF/DNS-rebinding protection
  • OpenAI vector-store file search, cross-session memory, token-budgeted context trimming
  • AST-based safety gate and prompt-injection screening for model-generated code
