On the web I ship production React & Next.js apps for clients across the Netherlands, USA, Singapore, and Indonesia. On mobile I build with Flutter — my app Capria Finance is launching soon.
I'm Bramsurya Johannes Paulus, a Frontend Engineer based in Bandung. For the last 4+ years I've been shipping production React and Next.js applications for clients across the Netherlands, USA, Singapore, and Indonesia.
I've worked on booking SaaS dashboards, property management apps, AI-powered food ordering platforms, government document systems, and Web3 marketplaces. On mobile I build with Flutter — including Capria Finance, a personal finance app I designed and built end-to-end, launching soon — alongside cross-platform PWAs shipped via Capacitor.
I care about TypeScript safety, code quality, and the small UX details that make a product feel finished.
I take projects from Figma to production — building the front end of dashboards, marketplaces, mobile apps, and marketing sites that real teams ship to real users.
Full React / Next.js builds with TypeScript — dashboards, SaaS, CMS, marketplaces, and consumer apps. Clean architecture, reusable components, shippable code.
Native mobile apps built with Flutter for iOS and Android, plus cross-platform PWAs shipped via Capacitor — native plugins for keyboard, splash, status bar, and app lifecycle handling.
Embeddable widgets, drag-and-drop schedulers, interactive maps, PDF generation, Stripe payments, blockchain wallet-connect, multi-language interfaces — the heavy stuff.
No percentages — they don't mean much. Instead, here's how frequently each tool actually shows up in my work.
A product I built end-to-end, plus client work across four countries. Client projects are under NDA — descriptions are anonymized to respect confidentiality.
A personal finance app — designed, built & shipped solo
Net-worth tracking with 6-month trends, monthly income vs. expense reports with per-category breakdowns, a transaction calendar, recurring subscriptions, debts & receivables, and savings goals. Magic-link auth and cloud sync via Supabase.
Booking SaaS for activity operators — dashboard, CMS, and a framework-agnostic embeddable widget that partner sites drop into their pages. Built multi-language UI, drag-and-drop daily availability scheduler, dynamic booking forms, and real-time pricing sync.
Four codebases ship as one product: consumer ordering web app with AI chatbot, admin dashboard with Stripe Connect payouts, animated corporate marketing site, and a merchant PWA on iOS & Android via Capacitor. Shared component patterns across all four.
Led frontend on a property management app — interactive Google Maps with clustered markers, drag-and-drop booking calendar, PDF report export, advanced sortable / filterable tables, and revenue analytics charts. Coordinated code reviews and release cycles.
NFT marketplace with wallet-connect flows, smart-contract calls for minting / listing / purchasing, and SSR-rendered token pages for SEO. Worked with the US-based client across timezones to ship iteratively.
Comprehensive school management app for a Montessori network. Implemented role-based UI for administrators, teachers, and parents; built reusable form and table components for student records and class scheduling.
Public document management app — upload, search, and access-control UI with secure document handling, role-based permissions, and audit-friendly request flows. Coordinated REST API contracts with the backend team.
Two roles, one consistent thread: ship production code, learn fast, collaborate across timezones.
Building production React & Next.js applications for international clients across the Netherlands, USA, Singapore, and Indonesia. Led frontend on a Bali property platform; shipped cross-platform PWAs to iOS & Android via Capacitor.
Built and maintained an e-commerce application — product catalog, cart, and checkout UI — with reusable, responsive components.
I'm open to new projects and roles. Drop me a note about what you're building — I usually reply within a day.
