I train custom models
& harness AI agents.

Hi, I'm Aviraj Khare — a decade of shipping software: platform engineering at Gojek, then AI infra and developer tools. Now I train custom models on Apple Silicon and build the harnesses that make AI agents actually work.

Spotlight: troy

Troy fine-tunes LLMs on your Mac. One YAML file becomes a LoRA training run on Apple Silicon — no notebooks, no boilerplate, no GPU rental.

  • SFT, DPO, ORPO and vision fine-tuning, built on MLX
  • Auto-detects your dataset format — alpaca, sharegpt, chat, completions, preference pairs
  • Chat with, evaluate, and serve the tuned model locally via an OpenAI-compatible API
  • Export to GGUF / Ollama, or push straight to Hugging Face

Things I've built

troy

Python · MLX

Fine-tune LLMs on Apple Silicon from a single YAML file. No notebooks, no boilerplate — describe the run, hit enter.

superdupermemory

Rust

A local-first memory layer for AI agents. Your agent remembers; your data never leaves the machine.

wasm_terminal

WASM · JS

A working WebAssembly terminal embedded inside a Notion page. Because why not.

yoyo

Rust · MCP

A local MCP server for code intelligence. Keeps coding agents grounded in the real codebase instead of hallucinating one.
