About the Book

I helped build the GitLab CI/CD platform.

I've spent OVER 3 years in my life consult clients to build effective CI/CD flow using GitLab.

It's possible to 10x your developer productivity (or more) with GitLab CI. You just need to know the right levers to pull.

Now, I want to share with you my ultimate GitLab CI cheatsheet.

Hi, I'm Abdu. I trained as an engineering physicist and turned to software engineer, tech mentor, consultant, and entrepreneur. I’m passionate about entrepreneurship, software engineering education, technology innovation, product management, and human-centered design.

I've worked with and contributed to businesses of various sizes—from the company I founded (Kulkul) to early-stage startups (Wonderlabs, ErudiFi), a rapidly growing startup (Midtrans), startup unicorns (Go-Jek, Picnic, Bol), a multi-billion dollar corporation (Microsoft), and even a non-profit (Open Learning Exchange). My roles have spanned Development, Testing, Operations, Scaling, Data, and Sales.

These days, I focus on documenting and sharing my experiences in software engineering, mentorship, and entrepreneurship through books, articles, newsletters, and various open online content. I capture lessons learned from real-world projects and cross-cultural collaboration.

I believe that software engineering, like many problem-solving fields, requires contextual solutions. What I brought to every company — from early-stage ErudiFi to unicorn startup Go-Jek — was a tailored, thoughtful approach, not just a blind application of best practices.

I'm currently working at Bol in the Netherlands, continuing to grow as a software engineer while writing and sharing what I’ve learned along the way.
