What I'm looking for

I seek roles where I can lead backend and architecture work, mentor engineers, drive AI/cloud integrations, and deliver scalable, customer-focused products.

I am a results-driven Principal Software Engineer with 7+ years building scalable, high-impact solutions for global brands such as OLX and DubizzleCars. I design robust architectures, lead cross-functional engineering teams, and deliver features that improve performance, security, and user engagement.

My work blends backend engineering, AI integrations, and cloud infrastructure (AWS) with strong mentorship and stakeholder communication. I have led major projects including auction and marketplace systems, implemented real-time bidding, payment integrations, and AI-driven features while driving continuous improvement and delivering on time and under budget.
