Berlin-based software engineer. I build things, sometimes because someone's paying me to, sometimes because I got annoyed by something at 11pm and decided to fix it.

By day, I lead engineering at TechMiners, a tech due diligence platform for VCs and private equity firms. Lots of data systems, AI workflows, and honest conversations with founders our amazing team of CTOs.

By night, I ship products under Nestor Code Crafters, my own company. Mostly small B2C apps, usually built to solve something I (or a friend) kept running into.

I care about the whole product. How it looks, how it feels, how it works, and the systems underneath that keep it honest. Velocity is nice. Taste is better.

• TechMiners: Data-driven tech and product due diligence for VCs and PE teams. I lead engineering across the platform, data systems, and AI agents.
• Smoketest: AI-powered browser testing. Write test flows in plain English, without selectors or Playwright maintenance.
• Nestornotes: AI-powered newsletter digest and knowledge hub. Turns your inbox firehose into something you can actually search and learn from. iOS app too.
• Vinoh: iOS wine journal. Log tastings, learn the language of wine, build a real taste profile.
• Kapier (coming soon): Privacy-first document intelligence. Ask questions across your documents without sending them anywhere you wouldn't want them to go.
• Vera (coming soon): AI voice journaling companion. Talk through your day, get something back worth keeping.
• arminayat.com: My site and writing archive. Essays on engineering, AI tools, and building products in public.
• GitNation talk: React Day Berlin 2024. How frontend engineers can prepare their teams for tech due diligence. Yes, there's a jousting knight analogy.

Most of my engineering work is private, client-facing, or product-side, so this isn't a complete archive of what I do. Think of it more as a public workbench than a portfolio.

If you're building around AI products, engineering teams, developer tools, or early-stage software, I'm almost always up for the conversation.
