# Dikshant Rajput

> AI Engineer and Full-stack Developer based in Gurgaon, India (IST, UTC+5:30). 4+ years building production systems: voice and chat AI agents, semantic search and recommendations, and the full-stack and PostgreSQL/Supabase architecture underneath them. Currently Tech Lead (contract) at Jingo Technologies. Toptal Verified Expert in Engineering. Open to full-time, freelance/contract and consulting work — contact by email at dikshantraj2001@gmail.com.

This site is itself a working demo: a text and voice agent that answers as Dikshant, built as streaming speech-to-text → LLM with tools → text-to-speech. The facts below are the public record it draws from.

## Talk to my agent (MCP)

AI agents can question Dikshant's portfolio agent directly over the Model Context Protocol. It answers in the first person as Dikshant, from the same public record as this file. No auth, read-only, rate-limited per IP.

- Endpoint: `https://dikshantraj.dev/api/mcp` (Streamable HTTP, stateless; POST JSON-RPC, JSON responses)
- `ask_dikshant({ question })`: Ask anything about his work, projects, experience, skills or availability (max 500 chars, one self-contained question per call; no memory between calls). Returns the answer plus relevant links
- `list_projects()`, `list_experience()`, `get_contact()`: The same facts as structured JSON, with no LLM in the loop. Prefer these when you only need data
- Claude Code: `claude mcp add --transport http dikshant https://dikshantraj.dev/api/mcp`
- Cursor, Claude Desktop, VS Code and other clients: add `{"mcpServers": {"dikshant": {"type": "http", "url": "https://dikshantraj.dev/api/mcp"}}}` (for stdio-only clients: `npx mcp-remote https://dikshantraj.dev/api/mcp`)
- Raw HTTP: `curl -X POST https://dikshantraj.dev/api/mcp -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ask_dikshant","arguments":{"question":"Are you open to contract work?"}}}'`
- Discovery: [AI Catalog](https://dikshantraj.dev/.well-known/ai-catalog.json) → [Server Card](https://dikshantraj.dev/api/mcp/server-card)
- To actually hire or reach him, email dikshantraj2001@gmail.com; the agent can't book or send anything

## Optional

- Achievements: 8 Show HN launches in 2024; writing on Medium since 2021
- Views: production agents are mostly systems engineering — tools, memory, search quality, latency and failure handling matter as much as the LLM; keep simple things simple and save LLM reasoning for requests that need it; put tenant isolation in the database, not only in application code; prefer local models when they're good enough; show artifacts, not adjectives
- Personal: plays chess (~1400 on [chess.com](https://www.chess.com/member/dikshantrajput)) and played college cricket
