About this session
This is a FAANG-style system design interview. I will ask one question that involves designing scalable systems from scratch. We will simulate a real-life interview so the experience would be the same.
Your mentor
I am a Senior Software Engineer at Booking.com, based in Amsterdam. Before Booking.com, I was working as a Senior Software Engineer in Singapore at Grab - the leading tech company in South East Asia in consumer services.
In 2025, together with two friends, we have launched our first startup. We built TravelMaker - an AI-powered travel companion based on state-of-the-art AI technology. More: https://travelmaker.app/
In my career so far, I have always been working as a backend engineer. I have experience in designing and building distributed systems at high scale and developing microservices and backend systems from scratch.
I also worked as an author for Educative.io. I have a full-fledged course in the platform. The course is about the fundamentals of distributed systems targeted at people with little to no experience in the field. The course can be found here: https://www.educative.io/courses/introduction-to-distributed-systems-for-dummies
In 2023, I launched my own newsletter, named Biweekly Engineering. The purpose of the newsletter is to share curated software engineering articles to its subscribers. You can find the newsletter here: https://biweekly-engineering.beehiiv.com/
I can help you with career decisions, technical interviews (both system design and coding interviews), standard coding practices, promotions in tech, good engineering culture, and overall growth as an engineer.
Both at Grab and Booking, I learned how to grow as an engineer while pushing for promotions to senior roles.
In terms of interviews, I interviewed with Grab, Meta, Amazon, Microsoft, and Booking.com. I always put rigorous effort into preparing, and quite fortunately, I managed to crack all of the companies.
If you are in need of help in progressing your career, both from a technical and growth perspective, I can certainly help you. I am looking forward to sharing my experience and knowledge with you so that you can excel in your career ahead!
