Jaime Rojas
Jaime Rojas is a backend engineer and builder based in Munich, with 15+ years of experience turning hard problems into working software. By day he's a Senior Backend Engineer at SafeNow. On the side, he's building Famlo — an AI-native family operating system where chores, finances, meals, goals, and the calendar all flow from one place: how families actually talk to each other.
Now
By day at SafeNow, by night at Famlo.
Going full beast-mode on AI — learning how the new models, tools, and patterns let one builder ship what used to take a small team. Famlo is the lab; every prototype either compounds into the product or teaches why it shouldn't.
The why starts personal: a young family far from home, and no app that actually held daily life together. The bigger why follows — Famlo would have needed a team a year ago. Today, with AI as leverage, it's doable solo, and the families it's built for don't have to wait for someone else to build it.
The deeper bet: AI doesn't just speed up the work, it changes what software is allowed to feel like. Famlo's signature — communication at the root, modules flowing into each other naturally — only exists because AI can finally be the connective tissue, not a feature in a settings menu.
Work
Each dot is a chapter — pick a year to read the story.

- Led zero-trust adoption and wrote documentation that helped other teams skip the hardest parts

Personio — The layoff
January 2024. Jaime was let go in the first wave of layoffs at the company that had brought his family to Munich — the end of Chapter II and the doorway into Chapter III. The story of what came next lives in the chapter intro above.
enmacc — Software Engineer
A European energy trading marketplace. Joined with genuine excitement after a tough job search — and learned quickly that enthusiasm alone can't bridge a fundamental mismatch in communication style, expectations, and working culture.
- Five months that taught more about cultural fit and self-knowledge than any successful role had
- Reinforced the value of asking the hard questions before signing — a lesson carried forward
SafeNow — Senior Backend Engineer
A personal safety platform built for the moments when seconds count. There are companies you join for the career move, and companies you join because the mission actually means something. SafeNow was the latter — the idea that software could be the difference between someone getting help in time, or not, is not something Jaime takes lightly.
- Designing and shipping Kotlin backend services built for global scale
- Championing test automation and continuous engineering improvement
- Fast-paced environment where quality and pace coexist by design
Famlo — Family Operating System
Built solo, driven by real life. No app actually held the family's life together after moving to Munich with twin 5-year-olds. Famlo is the answer — a family OS where communication is the root and everything else derives from it. Families talk, decisions follow, life happens. AI weaves the modules together so a complex platform feels like chatting with another member of the family.
- Comms-first by design — chores, meals, finances, goals, and calendar all derive from how the family already talks
- AI ties the modules together so the platform feels like a conversation, not an interface
- Privacy-first — no trackers, no third-party data sharing
- Waitlist beta, built entirely solo alongside full-time work
