Hallo — I'm Leo. Building cloud-native integrations on SAP BTP, Hybris & S/4HANA. Nine years shipping enterprise software — but still the same kid from Bắc Ninh who loves a good cà phê sữa đá.

01 / About

From writing Oracle ADF in 2012 to architecting SAP BTP microservices today — the through-line is making systems talk to each other.

The short version

I started my career at POSCO ICT Vietnam building steel manufacturing & logistics systems in Java/Oracle. Then came MoMo (M_Service) — the early days of Vietnam's e-wallet — where I learned what real transactional pressure feels like.

After detours through Persol (HR platforms) and Game Co. (payment gateways), I found my home in the SAP world at Robert Bosch Vietnam in 2017 — Fiori, UI5, ABAP, and my first SAP-Store-published apps.

Since then I've led teams at Laidon Consulting, co-built products live on the SAP Store with Conarum (Germany)Pro Conarum Future of Supply Chain and prosustain — and today I'm Senior Integration Engineer at HABA Group, connecting Hybris commerce to SAP BTP at European retail scale.

I care about clean integration architecture, developer experience, and shipping things that actually run in production on Monday morning.

When I'm not debugging OData, you'll find me…

#travel

On the road

Đà Lạt at 5am with coffee. Road trips through Central Vietnam. Remote working from anywhere with decent wifi.

#music

In the headphones

Indie, lo-fi, a bit of Trịnh Công Sơn. Music is how I context-switch between deep work sessions.

#coffee

At the cà phê

Phin drip, strong, just a touch of condensed milk. Best ideas happen at a quiet quán somewhere.

#saigon · #bắcninh

Between two cities

Born in Bắc Ninh, made in Sài Gòn. Bình Dương is the compromise — close to everything, expensive to none.

"Good integration is invisible. You only ever notice the bad kind — so I spend my days making sure nobody has to notice mine."
