About

Hai, I’m Dhika. A software developer, transit nerd (I run Buswayposting), and a weeb.

I watched Skip and Loafer (please watch Skip and Loafer) and A Place Further Than the Universe, listen to Hinatazaka46, and there’s a Mitsumi + Shima figurine sitting above my PC case. Chisato Nishikigi and Shigure Ui are up there too, so… yeah.

Experience

Software Engineer · Mbiz

Kuningan, Jakarta Selatan · – Present

  • Frontend engineer on Mbizmarket’s B2B procurement platform, working across a strangler-fig migration: maintaining legacy jQuery/PHP web apps (buyer, seller, admin) while incrementally rebuilding them as a modern Next.js monorepo (Turborepo + pnpm) with a shared design system.
  • Worked primarily on the buyer web app, helping migrate core procurement flows to Next.js App Router, including purchase orders, shipping and confirm-shipment/received flows, addendums, tax/DPP handling, invoices, reorder, and decimal-quantity ordering for government and business buyers.

  • Replaced Material UI v4 with Tailwind CSS and Headless UI, leveraging React Server Components to improve LCP by 58% (3.6s → 1.5s) and eliminate layout shifts (CLS 0.2 → 0) on real-user metrics, then followed up with an ongoing performance initiative (deferred scripts and modals, dynamic imports, image prioritization, preconnects).
  • Shipped platform features including QRIS payment, merchant rating and verification, and TKDN compliance display; hardened legacy code with SQL-injection sanitization; and helped establish frontend testing practices with Vitest and MSW.
