Two full-stack web apps and two native Android apps. Each write-up covers the problem, the architecture, and the trade-offs I made.
Storefront & CMSA storefront and custom CMS for a pempek shop in Serpong, South Tangerang. The owner manages the menu, promo banners, reviews, and contact details from an admin panel instead of asking me to change the code.
Multi-tenant SaaSA self-initiated multi-tenant project management app for freelancers: leads, clients, proposals, projects, tasks, invoices, and time tracking in one place, with a portal clients can log into.
A personal productivity Android app combining daily habit tracking, focus sessions with persistent background timer, and visual task urgency in a Neobrutalist design.
An offline-first Android expense tracker that keeps everything on the device: no account, no server, no sync. Receipt scanning and charts run locally.
