Frontend engineer building production web applications

I build React and Next.js interfaces around real product behavior, connecting APIs, state, validation, and responsive interactions.

Hi, I'm Tim.

At Serlzo, I build creator- and member-facing features, from email campaigns and a visual template builder to CRM imports, product setup, billing, courses, and team permissions. At Homie, I implemented rental-marketplace features for tenants, landlords, and inspectors, including listings, applications, and inspections.

I also build independent projects beyond the interface. TheDays is a habit and commitment tracker where progress accumulates across missed days. I built its React frontend and Node.js/PostgreSQL backend for authentication, persistence, daily tracking, and timezone-sensitive completion rules. For Felix & Gift, I built guest photo-upload and moderation flows with Supabase and Cloudinary, plus admin tools and tests.

I pay attention to details that can make an interaction fail: stale data, failed requests, unclear empty states, validation, and layouts that break on small screens.

How I work

Frontend is where I have the deepest experience and work most independently. I use AI tools throughout my workflow, and lean on them more heavily when projects take me into areas I’m still learning, such as backend APIs and persistence. On projects like TheDays, I define the behavior, review the implementation, test the result, debug problems, and deepen my understanding of the system as I work.
