Experience
11 years, since July 2015
Started my professional journey in July 2015 and have continued growing through backend engineering, platform work, and people leadership.
Daniel Yosep
Engineering Manager and Software Architect
I design and lead scalable digital products, bridging strong engineering execution with product impact across backend, platform, and AI initiatives.
About Me
Building reliable systems and growing teams that deliver consistently
Engineering Manager with hands-on experience in designing and building scalable backend systems, leading cross-functional teams, and fostering strong engineering practices. Focused on practical software architecture, workflow automation, and the thoughtful adoption of AI to enhance developer productivity
Current Position
Engineering Manager
I lead engineering execution with a focus on clarity, reliability, and outcomes that matter for the business and the team.
Current Company
Kawan Lama Group
I currently work at Kawan Lama Group, where I help teams build dependable systems and improve delivery quality.
Philosophy
Build systems, not heroes.
Great software is not measured by how much one engineer can build, but by how well a team can sustain, evolve, and improve it over time. I believe technology should solve business problems—not become the problem itself. That's why I encourage engineers to stay technology-agnostic, embrace continuous learning, and choose the right tools for each challenge. My mission is to build scalable platforms, grow adaptable engineering teams, and create systems that continue delivering value long after their original authors have moved on.
