Hello! I'm Supun 👨💻
Full-Stack & AI Engineer
Building Reliable, Scalable Products
Based in Singapore.
About.
I’m a Lead Full-Stack Engineer and Senior AI Engineer with 8+ years building systems that don’t fall apart under pressure. My work spans end to end: mobile apps, web platforms, backend services, cloud infrastructure, and modern GenAI solutions. I’ve delivered 25+ projects across multiple industries. I care about clean architecture, scalable design, and mentoring teams so they can ship faster without losing their sanity. I also consult for companies that want real engineering leadership instead of buzzwords. Recently earned my AWS Certified AI Practitioner credential, but honestly, the work speaks louder than the certificates. If it runs on code, I can build it. If it runs on the cloud, I can scale it. And if it’s a mess, I can fix it.
