Krishna Singh

Full-Stack AI Engineer building AI-native products, backend systems, and developer infrastructure.

I enjoy turning ideas into products, from architecture and APIs to AI workflows, deployment, and everything in between.

Currently obsessed with making software simpler, faster, and more autonomous.

Currently Building

FlientSec -> A developer security platform that continuously evaluates engineering workstations against organizational security policies and generates audit-ready evidence without relying on traditional MDM solutions.

Checkout -> https://github.com/Rarebuffalo/Flientsec

Things I Like Building

AI Agents • Backend Systems • Developer Tools • Security Products • Automation • APIs • Full-Stack SaaS • Infrastructure

Toolbox

AI: OpenAI • Gemini • LangGraph • RAG • FAISS • Prompt Engineering (currently exploring MCP)

Engineering Philosophy

Build something useful. Ship it. Learn from users. Repeat.

I care more about solving real problems than chasing shiny technologies. My favorite work sits where AI, backend engineering, and product design meet.
