About Me
A brief introduction of my journey as a software engineer.
Who Am I?



Alex Sirait
I am a senior software engineer and indie maker based in Batam, Indonesia. I don’t just write code — I build businesses, with a focus on high-performance architecture and product-market fit. A graduate of State Polytechnic of Batam (A.Md.Kom, GPA 3.96), I have bootstrapped platforms serving 300,000+ users without outside funding.
Today I lead my own studio, SIRAIT Tech, and engineer web solutions in the Digital Transformation team at PT Sat Nusapersada (PTSN). My track record includes CekCV.site, an AI CV/ATS analyzer used by 300,000+ job seekers, and Django WsapTo, an open-source framework trusted by 2,000+ developers. I’ve also mentored 50+ developers and help startups launch secure, scalable MVPs fast.
