Sanjay Kumar — Co-Founder

I build 0→1 MVPs for early-stage founders who need speed + quality. I collaborate with startups and contribute as a Full stack or a Founding Engineer - helping them ship fast, make smart technical decisions, and scale their engineering. Built production-grade systems as part of YC startup evaluation processes, including real-time AI pipelines and OAuth integrations - Freya Voice (YC S25) - Voice AI system, 133ms latency, delivered in 3 days - Vector Shift (YC S23) - OAuth 2.0 + API integration, delivered in 1 day Both assessments involved building production-ready features under tight deadlines. I handle: - Full-stack development (React, Python, Node.js) - AI/ML integration (OpenAI, LangChain, custom models) - Product thinking (built and launched products from 0→1) - DevOps & scaling (Docker, CI/CD, cloud infrastructure) If you're a founder who needs technical execution without hand-holding, let's talk.
