What I'm looking for

I seek roles where I can lead architecture and engineering teams to build secure, scalable systems, mentor engineers, and drive product-focused technical strategy.

I am a seasoned software engineer and technical architect with 12+ years building scalable mobile, web, and backend systems. I excel in system design, technical leadership and product management, driving migrations to microservices, implementing security and compliance solutions, and improving delivery through automation and A/B testing.

At Amarbank I defined architecture standards, introduced A/B testing that increased release accuracy by 70%, led refactors and an anonymizer engine for PCI‑DSS/GDPR compliance, and previously delivered performance and reliability gains across multiple companies through migrations, event‑driven design, and mentoring engineering teams.
