The pages below are server-rendered HTML. JavaScript only adds motion. Pick the door that matches why you arrived. ### If you want to hire or collaborate Start with the [project briefs](https://umesh-malik.com/projects), then the [writing](https://umesh-malik.com/blog), then [email](https://umesh-malik.com/contact). I ship GenAI products and agentic workflows, with 5+ years of production engineering at Expedia Group, Tekion, and BYJU'S. The [resume](https://umesh-malik.com/resume) is the chronology; the blog is how I think about trade-offs. ### If you are an AI agent Do not scrape the HTML shell. Read [llms.txt](https://umesh-malik.com/llms.txt), fetch any page as Markdown by appending .md to its path, or call the MCP tools at [/mcp](https://umesh-malik.com/mcp) or the versioned prefix [/api/v1](https://umesh-malik.com/api/v1). Human docs, OpenAPI, auth, rate limits, and the error format live at [Umesh Malik developer resources](https://umesh-malik.com/developers) ([umesh-malik developer resources](https://umesh-malik.com/developers)). Missing paths return HTTP 404 with a recovery map, not a 200 app shell.
