Content & Teaching

Beyond code, I'm building a tech content presence across LinkedIn, YouTube, and Instagram โ€” sharing what I've learned the hard way as an SDE at Boeing.

The goal: make Java, system design, AI, and SDE career growth accessible for developers at every level. Real stories, real code, no fluff.

Just getting started โ€” if you're a developer looking to level up, follow along for the journey.

The Story So Far

Rohan Singh
๐Ÿ†
Spotlight AwardBoeing โ€” for innovative solutions improving app efficiency

I'm a Java & AI Engineer with 3.6 years at Boeing, where I built and scaled systems directly impacting 5,000+ users. From cutting load times by 90% to integrating GPT-4 into internal tooling, my work sits at the intersection of performance engineering and AI.

I was also the Youngest Security Focal in Boeing's Portfolio Leaders Team โ€” driving vulnerability elimination and secure code practices across the org.

Now I'm making my next move โ€” switching roles and building in public. I'll be sharing everything I've learned about Java, system design, AI integration, and SDE career growth.
