Senior Tech Lead & Department Manager | Scaling Engineering Teams | Cloud-Native Architecture & Microservices

Belgrade, Serbia

About

Engineering leader with deep experience in backend systems and cloud-native architecture. Currently serving as Senior Tech Lead and Department Manager at Schneider Electric Hub for EnergySage, leading a feature team and mentor engineers for technical and leadership roles while overseeing strategic technical direction. Skilled in cloud architecture, backend frameworks (Python, FastAPI, Django), and building resilient microservices. I thrive at the intersection of hands-on engineering and leadership — aligning technology choices with business goals and scaling both teams and systems. Passionate about agentic AI and its role in the next generation of software engineering. Focused on scaling AI adoption responsibly — building the shared primitives, feedback loops, and trust infrastructure that empower engineers rather than replace their judgment.
