About Esteban

I'm a seasoned technical writer with over 10 years of experience crafting clear, precise documentation for advanced manufacturing, automation, AI, and media industries. I also create AI solutions for modern business, helping teams reduce repetitive work, streamline manual processes, organize scattered data, and build practical internal AI systems using tools like Ollama or similar local and controlled-environment solutions. I combine expertise in technical documentation, PLC programming, electrical schematics, prompt-driven tools, and software platforms like Arbortext and CMS with multilingual fluency in English, Spanish, and Swedish. estecas.com
