I turn complex financial workflows into software that feels clear.

An opinionated, local-first desktop tool that brings everyday checking, budgeting, recurring expenses, reminders, and credential storage into one focused workspace.

I am the sole architect and designer of the product’s look, feel, interaction model, and system structure. I use OpenAI Codex to help implement my designs. I approve every Codex step and personally read the code for integrity, retaining ownership of every product and architecture decision.

• 01Designed a modular event system that separates raw interface events, application behavior, rendering, API routes, and storage.
• 02Architected a local-first Electron application backed by Express and SQLite, with multiple ledgers, backups, restoration, and recoverable deletion.
• 03Defined security boundaries including sandboxed renderers, per-launch API sessions, contained navigation, validated payloads, and OS-backed credential encryption.
• 04Created a responsive, themeable ledger experience with budgeting, smart vendor/category workflows, configurable tables, and keyboard-accessible contextual help.
• 05Built a file-driven localization system and cross-platform release pipeline with automated package verification.

A reusable starting point for browser applications, built around plain JavaScript and clear responsibilities.

Small modules create the interface. Sensors capture clicks, keystrokes, and other browser events; behaviors decide what happens next. An Express server handles API requests, while storage and other product needs can be added as the application takes shape.

I use this approach instead of React for projects where I want direct control over the page and an explicit path from a user action to the code that handles it. Native JavaScript modules let me work without a JavaScript build step and keep the structure easy for me to inspect and extend.

• 01Separate interface structure, event handling, and visual styling so each has a clear place to change.
• 02Register new modules and optional plugins through shared contracts, keeping features organized as the project grows.
• 03Start with a small foundation and add persistence, authentication, and deployment choices when a product needs them.

As with Bank Ledger, Codex assists with implementation under my direction. I approve every step and read the code for integrity and consistency with the intended architecture.
