Miguel Minotti · AI Product Engineer

I listen.I build.I measure.Until it's routine.

I lead the first technology team at an industrial company with over 20 years of operation: an in-house CRM, AI agents on WhatsApp and integration with the legacy ERP. In the first week of the quarter, 6 of 6 salespeople used the CRM on 3 or more days.

Software and AI for real business workflows. I understand the workflow, build the solution and follow how people use it, with C#/.NET, React/Next.js, Python and PostgreSQL.

03 / How I work

From problem
to product.End to end.

Code is part of the solution.
So is understanding people.

  1. [ 01 ]

    Understand before building.

    I talk to users, observe their workflow and turn concrete problems into priorities.

    1. 01Sales team interviews brought CRM task management forward to the week after launch.
    2. 02A discovery interview with the manager gave rise to the AI SDR.
    Discovery
  2. [ 02 ]

    Give it shape. Make it work.

    I connect interfaces, business rules and data, with AI where it solves the problem.

    1. 01I migrated pricing from Excel/VBA to C#, comparing results against the workbook.
    2. 02I connected IARA to WhatsApp and the CRM APIs, with access scopes, validation and human confirmation.
    3. 03I ship through staging, Docker, Nginx and GitHub Actions, and test with xUnit, pytest and Testcontainers.
    Design × Engineering × AI
  3. [ 03 ]

    Ship it. Learn from it.

    I follow usage, inspect execution traces and adjust the next delivery.

    1. 01I measure adoption through work, not logins: 6 of 6 eligible salespeople in the week of Oct 5 to 9.
    2. 02When a model change made IARA worse, I rolled back while investigating.
    3. 03In the AI SDR, I measure the cost of each agent step alongside the conversation outcome.
    Ship → Learn → Iterate
04 / Layered background

My story
is part of
my method.

I learned programming by making games, explored physics concepts through simulations and worked with design clients. On Sophie, that background came together in art direction, development tools and product communication. Today, I bring that practice to operational software and AI.

  • Investigate

    Self-directed learning, science and observing real workflows.

  • Communicate

    Writing, awarded in a regional essay competition in 2019, presentations and negotiations with partners in English.

  • Create

    Code, art direction, illustration and music.

Physics studies, University of São Paulo, São Carlos campus. Studies paused. Building products became the focus of my work.

Outside work, I study philosophy, play piano and guitar, and keep a regular training routine.

06 / Writing

Small essays.

Short pieces about what I think and what I learn along the way. Written by me, may contain mistakes. When a piece had help from AI, its note says so.
