Invoice Generator
Invoice Generator for dealer and retail customers — live PDF preview, Biteship shipping integration, and a standalone portfolio demo
Brill Hepa Filter
Summary
Brill Hepa Filter became a compact but meaningful body of work because the scope covered both operational internal tools and a public-facing website experience in one business context.
The first phase focused on a price list system and an admin system that worked as one operational unit, even though they were deployed on different subdomains. The next phase shifted into a single homepage experience designed to present the brand more clearly.
That combination makes this company page useful as a grouped case study, because the projects are connected by the same business goal while still solving different product needs.
