Gonçalves.
Full Stack PHP Developer for 18 years. I work on long-term PHP products — modular architecture, tests, multi-tenancy and impeccable DX. I contribute back with 20+ Filament plugins and dozens of Laravel packages focused on concrete Brazilian market problems: tax invoicing, PIX integration, recurring billing, admin panels.
I live in Assis, SP. Open to consulting, SaaS partnerships, open source contributions and sponsorship. I reply within 48 business hours.

How I work.
Small packages, clear purposes.
Each plugin solves one specific problem. Composability > opinionated monoliths.
DX is UX for developers.
Clear docs, copy-paste examples, sensible defaults. If it takes 30 minutes to use, it is poorly made.
Parallel version support.
Filament v3, v4 and v5 all maintained. Production users cannot be forced to migrate on my schedule.
Brazilian market as focus.
CEP, CPF/CNPJ, PIX, LGPD, BRT timezone. Obvious things to us that international packages ignore.
See what I am building.
Filament plugins, Laravel packages and starter kits — all open source. Issues and PRs welcome.
