What I'm looking for

I am seeking senior roles building and securing production AI/LLM systems with strong MLOps, cloud-native practices, and a security-first culture.

I am an LLM engineer and AI security specialist with hands-on experience developing, fine-tuning, and deploying large language models for enterprise applications while integrating robust security protocols and MLOps. I have administered Linux and Windows servers, automated operational tasks with Python and Bash, and built secure cloud AI infrastructure using Docker and Kubernetes.

I led AI-powered document processing and OCR/NLP systems, conducted penetration testing on AI components, and collaborated with cybersecurity teams to mitigate adversarial and model integrity risks. My work emphasizes encrypted storage, IAM controls, and compliance with data-protection standards.

I also design full-stack web applications and secure APIs that connect AI models to production systems, implementing OAuth, encryption, and role-based access controls to ensure safe, scalable integrations that meet enterprise requirements.
