B2B e-commerce · building materials

BDA Group

PT. Bangun Delta Abadi

BDA (PT. Bangun Delta Abadi) has been selling building materials in Jakarta since 1969: tiles, floors, faucets, sinks, doors and more, from brands like Valpra, Hansgrohe and Cove. I led the team that built their B2B e-commerce platform. Today bdagroup.co.id is a friendly bilingual catalogue where you can browse by brand, filter the product library and download e-catalogues, and orders go through WhatsApp and their marketplace shops.

about

What I did

  • Led a team of 5 developers, from the first plan to launch day.
  • Advanced inventory management, so stock across a big catalogue stays honest.
  • Multi-tier pricing: different buyers see different prices.
  • Bulk ordering for project buyers who order by the pallet, not the piece.
  • Integrated logistics for heavy, awkward things like slabs and tiles.
  • Laravel on the backend, React on the front.
  • Live today: a searchable product library, a page per brand, downloadable e-catalogues and a blog, in Indonesian and English.
