Full Stack E-Commerce Platform
An end-to-end commerce platform — authentication, catalog, and payments — built around the conviction that checkout friction is a product problem, not a technical one.

Problem
Buying required too many decisions. Account creation, catalog navigation, and payment each introduced a moment where a motivated customer could reconsider. The drop-off wasn't concentrated in one broken step; it was distributed across a dozen small frictions that individually looked acceptable.
Solution
We rebuilt the path from intent to purchase as a single designed sequence rather than three separately-owned systems. Authentication became progressive — browse first, commit later. The catalog was structured around how people actually search rather than how inventory is stored. Payments were reduced to the smallest set of required inputs, with everything else deferred or inferred. Node.js and MongoDB gave us a flexible product schema that could absorb catalog changes without migrations blocking releases.
Outcome
Conversion improved because the number of places to abandon went down. Just as importantly, the team could ship catalog and pricing changes without coordinating a release, which changed how fast the business could respond to what it learned.

Approach
The decisions that shaped it.
- Mapped the funnel end to end and ranked frictions by cost, not by ease of fixing.
- Made account creation optional until the moment it was genuinely required.
- Modeled the catalog around search behavior rather than inventory structure.
- Kept the payment surface minimal and deferred every non-essential field.
