02What I build

  1. 01Product developmentFrom business problem to production-ready product: requirements with stakeholders, domain modelling, phasing, delivery and iteration on real feedback.CDC Manager: 37 stakeholder requirements, 7 phases
  2. 02Full stack applicationsFrontend, APIs, databases, authentication, payments, transactional email and logistics and invoicing integrations. All in TypeScript, from the data model to the component.Surfers Paradise: checkout with PIX, boleto and card
  3. 03Business automationAutomating repetitive workflows and operational processes: idempotent imports of legacy data, reminders and recurring expenses via cron, certified invoicing reported to the tax authority with no manual step. AI where it makes sense, not as decoration.Chi Sublime: certified invoicing via Moloni, cash crons

03Engineering principles

How I engineer

01Data integrityFinancial values are stored in integer cents, never floats.

Financial values are stored in integer cents, never floats. Every act, invoice or order line freezes price and commission at the moment it is recorded. Nothing is deleted: records are voided with author and reason, stock is corrected with movements, invoices are voided by credit note.

02Server authorityThe client is a suggestion. The server decides.

Prices are revalidated at checkout, coupons are validated server-side, permissions are checked on every action. The client is a suggestion; the server decides.

03Operational resilienceDouble booking, double charging and negative stock are prevented by transactions, not in the UI.

Double booking, double charging and negative stock are prevented by database transactions, not in the UI. If state diverges from what was expected, the operation aborts and nothing is left half done.

04MaintainabilityBoring conventions save weeks.

Strict TypeScript, error-free `tsc` before every delivery, predictable conventions and a clear separation between client and server. Boring conventions save weeks.

04Background

Business → Founder → Operations → Software
