AI-native tools · MCP servers · AI training

Tools your team actually uses.
Built really fast.

I build AI-native systems and internal tools around how your business already works, and connect them to Claude and ChatGPT so your team can work with real data in plain language.

What I build

01

AI-native systems & MCP servers

Your data and processes, available inside Claude or ChatGPT. I build MCP servers that let your team ask, update and act on real business data in plain language, with the permissions and audit trail a real system needs.

02

AI training for teams

Hands-on workshops that move a team from “we tried ChatGPT once” to daily habits: prompting on real work, connecting tools, and knowing what to trust. Built around your workflows, not generic demos.

03

Custom internal tools

When spreadsheets and off-the-shelf SaaS feel like a straitjacket, I build the app your process actually needs: dashboards, pipelines, finance and operations tools, and the automations between them.

Case study · my own product

Upstring: a coaching platform that lives inside Claude

Business coaches run their whole practice from Claude or ChatGPT: preparing sessions, logging them, tracking actions and goals, and sending DISC and VAK assessments. Their coachees follow their own progress from their own AI assistant.

  • Remote MCP server with 20+ tools, in production with coaching firms in Latin America
  • Every request runs as the signed-in user; the database decides what each person can see
  • Separate portal so clients see only what their coach shares
  • Built on Next.js, Supabase and Vercel

How I work

Fits how you work

No forcing your team into someone else’s process. The tool adapts to what you do and how you do it.

Automates the repetitive

Hand over the copy-paste, the reminders and the reports, and get back the hours your business needs.

Grows with you

No “enterprise tier” wall. Your tools evolve at the pace of your business.

Hey, I’m Miguel

Miguel Ortiz

I’m a generalist and a problem-solver. I’ve grown teams and departments in corporate environments and led operations for small boutique companies. I grasp strategy quickly, then build the tools that help teams and entrepreneurs execute and reach their goals fast.

Today most of that work is AI-native: connecting the systems a business already has to the AI assistants its people already use, and teaching them to get real value from it.

What clients say

Oil & Gas
“Miguel is a reTool expert who bring deep technical knowledge, a creative practical approach to problem solving, and brings a collaborative spirit to projects. He knows the reTool platform inside and out & has built very complex applications for us involving genAI, knowledge graphs (neo4j), and custom UI components and a load of third party API integrations. Give Miguel a problem and he will come up with a creative solution. I’ve managed programmers for over 25 years, he is easily in the top 1%”
Jeff DalglieshData² · via Contra
Private Equity
“I worked with Miguel to build an early-stage pilot of a specialized operating system for the private equity space, and he was outstanding. He’s highly proficient in Retool and executes quickly, but what really sets him apart is his strategic thinking. He approached the work as a partner, not just a developer. … The pilot we developed is now a strong foundation for production, and I would work with him again without hesitation.”
Peter LyonsFounder, Valience · via LinkedIn
Manufacturing
“Miguel is one of the most professional and effective consultants I’ve ever worked with. … What really sets Miguel apart is his approach to collaboration—he genuinely cares about empowering his clients. Rather than treating every interaction as a billable moment, he focuses on teaching and knowledge-sharing so your team can become self-sufficient and successful long after the engagement ends. … He’s the kind of partner you want involved early, because he elevates both the solution and the team building it.”
Lucas FerreiraInnovation & workflow lead, MBA · via LinkedIn
