Introduction to Gorka Hernandez's personal blog: AI automation, iOS development, FinTech and technical SEO with practical judgment.

May 10, 2026 2 min readby Gorka Hernandez Villalon

Welcome. This is the first post on my personal portfolio blog. Over the next months I will publish what I have been building privately for years: useful software at the intersection of AI automation, native iOS development and quantitative analysis.

Why a personal blog and not only social media

Twitter and LinkedIn are useful for distribution, but they are not great at preserving knowledge. Content that is actually valuable expires in days when it only lives in a feed. Here I have three goals:

  1. Document repeatable processes I solve more than once, such as n8n automations, iOS builds and financial data pipelines.
  2. Share lessons from real projects: what worked, what did not, and what I would change.
  3. Create entry points for recruiters, clients and peers who want to understand how I think without needing to book a call first.

What I will publish

  • Automation with n8n and LLMs: multi-tenant architectures, agent design patterns and real integrations with Gmail, WhatsApp Business and CRMs.
  • iOS development: SwiftUI, CoreData, MVVM patterns, App Store publishing and zero-data privacy.
  • FinTech and quantitative analysis: rigorous backtesting with Pandas, risk metrics such as Sharpe, Sortino and Calmar, and walk-forward analysis.
  • Technical SEO and GEO: how to structure a website for Google and generative engines such as ChatGPT, Perplexity and Gemini.
  • Case studies from my own projects: how I built GymTracker, the SEPE bot featured by Chema Alonso, or the architecture behind NexaVision AI.

How to follow along

There is no newsletter yet, but RSS and email updates are coming. For now you can follow me on GitHub, LinkedIn, Instagram (@gorka.tech), TikTok (@gorka.tech) and YouTube (@thePalms1).

If there is a topic you would like to read about, write to me through the contact page. This blog grows with the questions from the people who read it.

See you soon.
