I build developer tools for the AI era. I wrote zac, a coding agent from scratch in Zig, and cdesign, a marketplace that turns real websites into specs AI agents can build from.

Profile

Builder at heart

Yukti Kholiwal @yuktikholiwal

I'm a software engineer who ships fast, mostly building developer tools around large language models. I wrote zac, a coding agent built from scratch in Zig with zero dependencies, and cdesign, which scrapes real websites into installable design specs so AI agents build on-brand UI (shipped as an npm CLI). Before that I founded 9thgen.ai, a voice-agent platform now taking calls for paying clients. At Y Lift I inherited an undocumented production app, taught myself .NET and Blazor from scratch, and shipped a full platform migration in one month for 10,000+ monthly users at 99.8% uptime. Hand me an unfamiliar codebase and I'll get something working. (I also hold multiple years of US work authorization, so sponsorship isn't a near-term concern.)

Technical focus

Skills

I work across the whole stack of AI product development. On the model side I've built real-time voice pipelines, agentic tool-loops, and RAG-style workflows against the Anthropic, OpenAI, and OpenRouter APIs, and I wrote a coding agent from scratch in Zig. On the frontend I ship React, Next.js, and TypeScript interfaces. On the backend I've worked in FastAPI, .NET, and Postgres, and provisioned real cloud infrastructure with CloudFormation and the AWS SDK. The part I like most is the messy middle: taking a raw LLM capability and making it reliable enough for people to actually use.
