Xendit's Merchant Dashboard

Multi-brand fintech dashboard built from 14 micro-frontends and the BFF gateways behind it.

Context

Xendit’s merchant dashboard is where businesses manage payments, payouts, balances, transactions and API integrations. Several product teams ship into it, under several brands.

What I did

I started as an engineer and became architect and team lead of a team of five:

A Module Federation monorepo: 14 micro-frontends, 3 BFF gateways and 3 shared libraries, so product teams release on their own.
White-labelling for 4 fintech brands from one codebase.
Rebuilt the BFF gateway as an Open Host Service: one documented protocol for every domain service instead of custom translation per service.
A TUI launcher that manages 21 git submodules for local development.
Ran the team’s technical interviews.

Results

Integration time with domain services halved, latency lowered, and gateway errors almost disappeared.
