Backend architect solving expensive infrastructure problems.
I’m Dulan Wirajith Lokunarangodage - a Senior Backend & Cloud Engineer based in Cyberjaya, Malaysia. I specialize in designing and building backend systems at scale: architecting SaaS platforms that handle millions of daily transactions, leading zero-downtime migrations from legacy monoliths to cloud-native architectures, and optimizing AWS infrastructure for reliability, performance, and cost.
My focus: Solving high-cost backend problems most engineers avoid; complex system migrations, distributed architecture redesigns, elastically scalable infrastructure, technical debt reduction, and production reliability. The kind of work that directly improves performance, lowers risk, and directly impacts your company’s bottom line.
I architect the systems behind growth.
Not the features. The foundations.
My career has been about fixing broken systems. Over 7 years, I've learned that most engineering time is wasted building on faulty foundations. I take systems that are expensive to operate, slow to evolve, and risky to change, and transform them into platforms that compound in value.
I've done this across vehicle marketplaces handling millions of listings, real-time bidding systems processing 1M+ transactions daily, and enterprise SaaS platforms. Every project reinforced the same truth:
“Build for 10x demand. Design for zero regrets.”
Three principles guide every architectural decision I make:

I'm selective about the projects I take on - but if it's ambitious and worth building, let's talk.
