Software Gardener

Cultivating code, growing teams, and nurturing systems that thrive.

From hands-on coding to leading cross-functional engineering teams, my journey from Software Developer to CTO-level leadership has been defined by a relentless focus on building scalable systems, driving technical excellence, and nurturing high-performing teams.

I bring a rare combination of deep technical expertise, architectural leadership, and people-first management that enables organizations to ship impactful, future-proof software.

As a Principal Engineering Manager, I lead from both the whiteboard and the war room — defining technical direction, managing engineering execution, and empowering teams to deliver scalable, resilient, and maintainable systems.

My leadership spans modern architectural approaches — microservices, cloud-native platforms, and event-driven systems — combined with a strong execution focus and pragmatic decision-making.
