Hi, my name is
Bao
I build reliable and high-performance SAP solutions with ABAP
I'm a Senior ABAP Developer specializing in designing and developing scalable SAP solutions for S/4HANA Cloud and On-Premise systems
01. About Me
With over 8 years in the industry, my journey began as an ABAP developer and has since evolved to roles like Technical Lead and Senior Specialist. My passion extends beyond just writing code; I am dedicated to architecting solutions that genuinely solve core business challenges.
I believe that an excellent technical solution is defined by its performance and maintainability. This mindset shapes how I design and build ABAP solutions, focusing on performance, clarity, and long-term maintainability, from optimizing code on SAP HANA to mentoring the next generation of developers.
Here are a few technologies I've been working with recently:
- SAP S/4HANA & ECC
