Engineering reliability
at financial scale

I'm a Deputy Head of System at Sonatra Microfinance with deep expertise in designing, deploying, and maintaining enterprise-grade IT infrastructure for financial services. My career is focused entirely on systems that cannot afford to fail.

Specializing in core banking operations, I manage the full stack of enterprise IT — from Microsoft SQL Server and Windows Server environments to Cisco networking and Linux VPS infrastructure — ensuring uptime and reliability for daily financial operations.

My approach combines rigorous technical discipline with a practical automation mindset: every system I build is designed for resilience, standardized operations, and long-term maintainability. I build processes that work even when I'm not in the room.
