Hi, I'm Ranjan Singh 👋

Gen AI & Product Engineer | Open-Source Maker

⤷ I'm Lead Engineer at Telos, with nearly a decade of experience shipping production AI and user-facing systems, hopelessly in love with TypeScript, React Native, and pushing the boundaries of system architecture. I specialize in building high-performance applications and crafting clean, modern user experiences.

Whether I'm designing complex LangGraph workflows, focusing on agent adherence in multi-agent orchestration, or setting up detailed growth analytics, my goal is always to build scalable, high-impact software. The part I care most about is what happens to your data on the way to the model, which is what led me to build Omit. Plus, I love making terrible jokes and puns, so working with AI models is a match made in heaven.

🛠️ What I'm Building

  • Omit: A suite of Windows apps that detect and redact PII entirely on-device. No cloud, no accounts, no telemetry. It grew out of the privacy-by-design pipeline I built at Telos with Microsoft Presidio, and it's releasing soon.
  • Shelly: A minimalist, cross-platform terminal utility that optimizes AI coding workflows with a floating "notch" UI and live Claude Code status tracking.
  • Telos: An AI life coach and journaling platform. Multi-agent LLM system on LangChain and LangGraph, with long-term memory via Zep and retrieval grounded in pgvector.

📦 Open Source

  • sharp-multer: Multer storage engine that uses Sharp to auto-optimize and resize uploads (JPG / PNG / WebP) on the fly.
  • rn-tour-copilot: React Native walkthrough library with a fully customizable tooltip UI, pre- and post-step hooks, and better multi-step navigation.
  • rn-country-code-picker: Lightweight, easy-to-use country code picker for React Native.
  • markdown-preview-skill: Offline live-reload Markdown preview for Claude Code, with GitHub dark theme and Mermaid support.
