Nino Risteski
I’m a Founding ML Engineer at AIRecruitPro, an open-source contributor, and a self-taught builder who likes learning by making things from scratch.
Most of my work sits somewhere between AI systems, product engineering, and startups. I care about building useful software, understanding the lower-level pieces behind modern ML, and moving quickly from rough idea to something real.
I spend a lot of time around multimodal models, GPU-accelerated training, ML infrastructure, and small tools that remove friction from everyday work.
Lately I’ve been digging into GPU kernels, memory bandwidth, and matrix multiplication performance.
Projects
METAL_SGEMM_M4
Metal compute shader experiments for SGEMM (4x4 tiles) that explore Apple GPU optimization and benchmarking.
TinyPilot
AI agent that helps you learn TinyGrad and keeps you updated on bounties, featuring RAG with ChromaDB and GPT integration.

Tinygrad
- delete extra cast in decompositions #14517 (Feb 2026) — the extra cast is redundant, bitcast(d.dtype) already returns a float.
- optim empty shard #13513 (Dec 2025) — optimized empty shards so the distributed optimizer skips useless work.
- rope cache optim for jit prune in llm.py (Aug 2025) — cached ROPE calculations so the JIT prune path reuses angles instead of recomputing them.
- adding enable_gqa in SDPA (Jul 2025) — added PyTorch-style grouped query attention plus coverage.
- clean up unused imports in examples and update CI linting (Jun 2025) — cleaned unused imports and wired Ruff so examples stay linted.
- fix test logcumsumexp broken devectorize=0 (Jun 2025) — masked before `exp` and used dtype-aware sentinels to stop NaNs.
- small fix replacing download_file with fetch (Jun 2025) — swapped ad-hoc download glue with the canonical `fetch` helper.
