$>_ Selected projects
Case studies in system design and engineering leadership — the payments and platform work behind a decade in FinTech, and the products I build end-to-end on my own stack. Each one is a decision worth explaining, not a tech-stack checklist.
A personal finance platform: accounts, budgets, credit cards, loans, assets, and multi-currency tracking. In active development, with plans to become a standalone product.
A deck-building and collection tool built around one decision: a single domain layer serving both a human UI and programmatic/AI-agent callers with no shared context.
A multi-tenant SaaS for small production studios (3D printing, laser, porcelain): costing, inventory, production queues, and billing. Preparing for launch.
Digital access to venues and experiences in Bogotá. I built the initial infrastructure and backend; today I review PRs as an outside contributor.
A macOS menu bar app to keep an eye on active AI coding sessions, with an iPhone companion. Heading to the App Store.
$>_ What I maintain
Open-source packages I keep alive — an ongoing responsibility, not a past project. The full story is in the modernization case study.
