Turning complex legacy problems into agile, scalable, and automated solutions.
I'm the sole software developer at Perains ON Technology (since May 2026), where I research, architect, design, and ship an ERP for Brazilian accounting — from database schema and tax rules to UI, documents generation, and CI. I also run my own cloud infrastructure on Oracle Cloud.
- Pursuing a Bachelor's in Computer Science at Descomplica Uniamerica (Class of 2029)
- Building and modernizing Perains ON Systems with Go, TypeScript, React, and PostgreSQL
- Administering Oracle Cloud Infrastructure environments
- Currently deepening Cloud Computing and Software Architecture
- Daily driver: Linux
I design and run my own AI agent harness on OpenCode — the scaffolding around the model matters as much as the model itself:
- Custom subagents & skills — specialized agents (mapping, coding, review) with discoverable skill workflows
- Tool integration — LSP servers (gopls, pyright, TypeScript, Postgres) and MCP for external tools
- Persistent memory — SQLite-backed facts and session checkpoints that outlive the conversation
- Model routing & evaluation — a multi-provider router plus a 75-model evaluation battery measuring real tool-use capability

PerainsON Technology — Solo Software Developer Since May 2026
- Researched, architected, and built an ERP for Brazilian accounting from zero — schema, business rules, API, and UI.
- Implemented the payroll workflow: preview → findings → operator approval → confirm/cancel, with CSV export and audit trails.
- Built an API-first backend with go-chi, sqlc, pgx, and golang-migrate — TypeScript client generated from the OpenAPI spec with orval.
- Delivered a typed React + TypeScript frontend governed by a design system of global tokens (shadcn/Tailwind, light + dark, zero hardcoded colors), with Vitest unit tests and Playwright E2E.
- Established CI (
make ci): lint, tests, and build gates on every change.
