Nurhak Altın

I build AI agents that do real work in production.

Lead Application Developer & Applied AI Engineer at APS Group

I lead development on Cohero, APS Group's AI-powered omnichannel content platform, and design agentic workflows where orchestrated agents code, review and test with human approval gates and clear cost visibility. Before AI agents, I worked on computer vision, embedded systems and large frontend platforms. That range is still how I work: from the model to the interface to the hardware.

Selected work

RPad

rpad.app

Turns an iPhone, iPad or Apple Watch into a trackpad, keyboard and presentation remote for a Mac, paired once with a code and end-to-end encrypted. Built end-to-end with an agentic workflow: a PM agent plans each milestone, a dev agent implements it, and a QA agent checks it against written expectations before the next one starts.

Hodierna

hodierna.app

An offline-first logbook for a newborn's first months. Every entry is written to the device first and synced in the background, so it works at 3am on one bar of signal. Parents share one book, each with their own access level. Includes an AI assistant on Cloudflare Workers AI with retrieval (RAG) over a Vectorize index.

Agents

Agent orchestration platform

Runs software work end-to-end: Mastra and Inngest durable workflows orchestrate Claude Agent SDK workers on self-hosted nodes, traced in Langfuse. Multi-tenant auth with SSO step-up and SCIM.

Multi-model

Hybrid local + cloud AI stack

Local models (32B coding models via Ollama on Apple Silicon) working alongside Claude. A Telegram bot hands natural-language tasks to Claude Code behind human approval gates; a Python agent automates a media pipeline.

HomeHub

React Native / Expo property-search app built with a multi-agent Claude Code workflow: product-owner, developer and reviewer agents work from structured task files, with designs synced from Figma.

iOS

KMklopt In development

Native iOS and CarPlay mileage log for Dutch lease drivers, built to be audit-ready for the Belastingdienst. It reconstructs past trips from a driver's known routine, and every reconstructed trip stays a draft until the driver confirms it.
