AUTOMATION · APPLIED AI · INTEGRATIONS · 2026

Maycon Ferreira / Rio de Janeiro, Brazil

Systemsthat solvedaily work.

I turn manual processes and operational routines into automations and AI-powered solutions that work in daily operations.

I work from discovery through production support, combining self-hosted n8n and Power Automate, Python/APIs, data/BI and applied AI. I choose the tool according to the process and keep human review and traceability where risk requires them.

EXPERIENCE AND COLLABORATION

I work close to the people and processes.

I learn how teams work, build solutions for real needs and stay involved after delivery.

Grupo Vesper — Vesper Equipamentos EX e Vent Rio Equipamentos

Junior Process Automation Technician official title

In my day-to-day work, I talk with teams, build automations and internal systems, and take part in IT operations by supporting users and following solutions in an industrial environment.

Independent collaborative project

B2B SaaS platform

Collaborative development from the beginning

I have collaborated with another developer on a B2B SaaS platform from its early design. I contribute to product workflows, permissions and tenant data isolation. Businesses use the platform; this work is independent of my current role.

Freelance IT Instructor

Paid weekly classes

I teach office tools, Excel, Power BI, Power Query, VBA, Windows and Linux fundamentals to learners with different levels of experience.

Oct. 2024 — Mar. 2025

Compass UOL

Data Engineering Scholarship Program

I took part in practical sprints using Python, SQL, Docker and AWS, building data flows from ingestion through analytical queries.

HOW I WORK

From a loosely defined request to a supported system.

I talk with the people who use the process, map exceptions and turn the need into a solution that can be deployed, explained and monitored.
  1. 01

    Context

    I understand the need, users, environment and expected outcome.

  2. 02

    Process and risks

    I map the current flow, exceptions, sensitive data, dependencies and failure points.

  3. 03

    Architecture and rules

    I define the source of truth, permissions, approvals, integrations and recovery.

  4. 04

    Build

    I develop the system, automation, interface, persistence and contracts.

  5. 05

    Deployment

    I install, configure, document and train the people who will use it.

  6. 06

    Evolution

    I monitor logs, fix failures and improve the solution based on real use.
