My deepest experience is in React and Next.js, building interfaces around APIs, application state, validation, and responsive behavior. At Serlzo I built features for campaigns, CRM, commerce, and communities; at Homie I implemented rental marketplace experiences; independently, I built TheDays.

Selected work

SaaS features alongside independent builds

TheDays

An independently built habit and commitment tracker that counts completed days cumulatively, so missed days do not erase progress. I built its React frontend and Node.js/PostgreSQL backend for authentication, persistence, daily tracking, and timezone-sensitive completion rules.

Multi-step application flows

Campaign, CRM, commerce, and account features shaped around the rules users need to complete each task.

API-connected interfaces

React and Next.js interfaces connected to platform APIs, with careful state, loading, validation, and error handling.

Independent builds beyond the UI

TheDays extends my frontend work into authentication, persistence, and timezone-sensitive tracking across a React app and Node.js/PostgreSQL API.
