Sandeep Kumar Penchala — I build platforms, teams, and AI-native tools that help developers ship faster — from idea to production. Engineering Manager & Staff Software Engineer based in McKinney, TX, with 16+ years shipping mobile and backend systems at Okta, DocuSign, Samsung SmartThings, and Visa.
I've scaled teams from 2 to 10+ engineers with 95%+ retention, coached engineers through growth and promotion, and driven platform strategy across iOS, Android, and backend-integrated systems. Creator of the largest open-source AI skill collection (202 skills, 29 domains) and Lantern — an AI-native community platform. I ship open-source tools, build full-stack products, and create agent-agnostic skills that work across Claude Code, Copilot CLI, Cursor, OpenClaw, and Gemini CLI.
