What I'm looking for

I seek senior technical leadership roles building scalable, cloud-native systems and AI-integrated platforms at ethical, growth-oriented companies with strong engineering culture and opportunities to mentor and scale teams.

I am a Senior Software Architect and Tech Lead with 15+ years of international experience designing and scaling high-availability backend systems, modernizing monoliths into massive-scale microservices, and integrating AI to deliver real-time operational insights. I have led engineering teams at top-tier firms, reduced processing runtimes by over 80%, and built LLM-integrated analytics and consumer AI products end-to-end.

I specialize in cloud-native development, event-driven architectures, and data consistency for high-concurrency environments across sectors including Logistics, HealthTech, Agritech, and E-commerce. I prioritize ethical, socially responsible companies and bring hands-on leadership in system architecture, CI/CD optimization, and technical onboarding to accelerate team impact.
