Alejandro prompting in Claude Code — shipping production software with agentic AI

Alejandro Hernández Lara

Founder @ Ale Hernández SpA & KaiNext Solutions Limitada · Senior Consultant @ Thoughtworks

Platform engineering · applied AI · agentic workflows — I diagnose before I build, then I ship.

alehernandez.cl kainext.cl LinkedIn Email Built with Claude Code Based in Santiago, Chile


I work in the space between code and capital — designing scalable architecture, applied AI, and platform modernization for production systems at enterprise scale. I diagnose before I build: years at the intersection of engineering and business operations taught me to read a system as a single piece, from the database to the P&L.

  • 🏛️ Thoughtworks — Senior Consultant (P4), embedded in platform engineering for a major airline: cloud-native foundations, developer self-service tooling, and AI-assisted engineering in regulated, high-stakes environments.
  • 🏢 Ale Hernández SpA — my own company, where I build and ship my own products end-to-end and run an agent-orchestration practice with uncompromising engineering rigor.
  • 🚀 KaiNext Solutions Limitada — my software consultancy, delivering production systems and audits for clients.

🔭 Now: turning NutriCoach from dogfooding into a launched product, under Ale Hernández SpA.

⚡ How I build

Claude Code is my primary environment — I run an agent-orchestration practice across a multi-domain command center, so software gets built, modernized, and audited with agents under tight engineering rigor. Most of what I ship runs on Railway.

Deploy on Railway with referral code KJa0VN
