What I'm looking for

I’m looking for a mission-driven team where I can lead end-to-end engineering—building scalable services, strengthening security (ISO/DevSecOps), and using automation/AI to improve reliability, speed, and measurable business outcomes.

I’m a dynamic IT professional with over 10 years of hands-on experience in software engineering, cloud architecture, DevOps, and cybersecurity, complemented by AI/ML research expertise. I build scalable, high-performance systems—leading microservices architecture projects that improved system scalability by 40% and reduced deployment times by 25% using Docker, Kubernetes, and AWS ECS.

I also focus deeply on security and operational excellence, implementing ISO 27001-compliant cybersecurity measures to achieve zero breaches over 18 months. From optimizing e-commerce performance with React.js, Node.js, and AWS CloudFront to pioneering TensorFlow/scikit-learn machine learning (95% accuracy in species identification), I balance strategic leadership with hands-on execution—mentoring teams to increase productivity by 25% and enabling faster, safer delivery through CI/CD, IaC, and DevSecOps.
