Hi, my name is
Lazuardy.
Software Engineer
Full-stack engineer with deep roots in backend and automation. I ship the UI, the API, and the scalable infrastructure underneath.
__About Me
Hello! My name is Lazuardy Khatulistiwa. I'm a software engineer based in Jakarta, Indonesia. I started building for the web in 2018 when a small side project to bypass ads for downloadable content turned into a crash course in how the internet actually works. That early tinkering sparked a deep interest in backend engineering, scraping, and automation.
Since then, I've worked as a software engineer at Nodeflux building production backends with AI integration, and spent over five years freelancing on Upwork with Top Rated Plus status. I shipped for clients worldwide, including Chegg, Woflow, Needles, and Disrupt Social, before leaving the platform at the end of 2025. Working across different time zones and industries gave me a strong sense for building systems that are reliable, maintainable, and built to last.
Currently, I'm at a stealth company building undetectable scraping infrastructure with browser fingerprinting. Most of my time goes into designing stealth automation systems, anti-detection layers, and high-throughput data collection pipelines.
