About me

I'm Gabriel Maciel, a software developer and Software Engineering student from Belo Horizonte, Brazil.

I started studying programming in 2023, while in my second year of high school. Today I take part in every stage of the cycle: defining the solution, modelling the business rules, implementation, infrastructure, deployment and keeping things running in production.

I build systems, APIs, integrations and automations, with a stronger focus on backend. I work with technologies like C#, PHP, Laravel, Python and PostgreSQL, helping build solutions that run in real production environments.

I am an active practitioner of AI-Assisted Development. Cursor, Claude Code, Codex and Trae are part of my daily workflow, and context engineering is what lets me ship fast without giving up architecture and quality.

My curiosity goes beyond code. I like understanding how things work, exploring new technologies and turning ideas into projects. I am interested in entrepreneurship, economics, literature, music and new experiences.

Away from screens, I'm probably planning my next trip.

Career

    1. Full stack developer Full time

      • I develop the company's internal hub, in Laravel and SQL Server, used by finance, accounting, logistics, sales, after-sales and IT. I have made more than 160 commits to it.
      • I built the configurable accounting close: tasks per branch and owner, deadlines, delay justifications, attachments, history and automatic deadline warnings.
      • I built finance's account statement module, with reconciliation, status filters and Excel export by group, plus the logistics module, after-sales cycle counting and debit notes in PDF.
      • I brought AI into the company's routine: an assistant built on the Anthropic API that explains the gaps between the Power BI margin and the management accounts, and a Node API that queries the ERP read-only, with function calling, key authentication and rate limiting.
      • I built the API that shows the status of the Python automations in the hub (scheduled, running, done or failed) without exposing scripts, paths or files.
