Aliquant

Every account you own, on one screen.

Aliquant is a personal finance app built on Plaid account linking: every account you own on one screen, sliced the way you think about your money — not the way your bank does. It's engineered like a production system, not a side project: a modular Swift 6 codebase with 480 tests across 46 suites.

Aliquant dashboard: a donut chart splitting one brokerage balance into buckets, with the unassigned remainder shown
Buckets screen: accounts with assigned and unassigned amounts, plus goal rings showing progress toward each target
Bucket editor: goal or reserve, an optional target, and a rule that takes a fixed amount, a percentage, or the remainder of an account
Welcome screen explaining buckets laid over real balances

Features

What it does

One screen

Checking, savings, cards, and investments from every institution, unified into a single view.

Your slices

Group and total accounts the way you actually think about money — not by institution.

Plaid linking

Bank connections through Plaid's Link flow, exchanged and stored server-side, never on device.

Modular core

Domain logic lives in SPM modules with no UI dependency — testable, portable, strict-concurrency clean.

Architecture

How it's built

iOSSwift 6 + SwiftUI, split into AliquantCore / AliquantUI / AliquantStore SPM modules
Testing480 tests across 46 suites — the domain layer is fully exercised without the UI
LinkingPlaid account linking via Supabase edge functions (link-token, link-exchange)
BackendSupabase Postgres with row-level security
WebA Cloudflare Worker serves aliquant.app and the link.aliquant.app Universal Links endpoint; my.aliquant.app is the signed-in web client — a Vite-built single-page app behind a strict default-src 'none' policy, deliberately kept out of search indexes
