Iwan Hadi Setiawan

I’m a frontend developer specializing in data-heavy admin dashboards and internal tools. I turn complex, high-stakes data into fast, reliable interfaces.

With 3+ years of production experience, I’ve shipped back-office systems for Bank Mega (CT Corp) and enterprise clients in mining and energy—covering KYC, payments, reconciliation, loyalty, and document management. I focus on building interfaces operations teams use daily.

I use Next.js and TypeScript with TanStack Table to deliver advanced tables, filtering, and pagination for transaction-heavy systems. I also contribute full-stack when needed using Node.js, Fastify, and PostgreSQL—plus migrations like moving a payment-gateway checkout from Laravel to Next.js without disrupting payment flows.

Through freelancing, I stabilized and extended production dashboards with consistent role-based workflows, and built an end-to-end custom CMS + back-office dashboard for gas-distribution operations. I’m open to remote contract / part-time engagements and I value clean, maintainable code that keeps data-grid performance and UX dependable.
