Case study
BJB Holistic Advice — Micro-Frontends at Scale
Jun 2023 – May 2025
Delivering micro-frontends for a private banking platform, integrated across multiple domains and two regional teams.
Problem
BJB's Agile Holistic Advice initiative needed a standalone frontend team to build and maintain digital advisory tools — personalized investment ideas and relationship-manager tooling — integrated into a larger, multi-team platform spanning Singapore and Vietnam.
Approach
- Built high-quality micro-frontends using Module Federation, integrated with multiple backend domains
- Worked within a SAFe delivery model, coordinating closely with parallel BJB teams
- Stack: AngularJS, Module Federation, .NET, MS SQL
My Role
Delivered frontend work as part of "Team Heka," a Zühlke-Vietnam team working hand-in-hand with Singapore-based teams on shared platform components.
Outcome
Improved client experience (personalized investment ideas) and relationship-manager efficiency across a long-running, multi-team engagement (~2 years).
