AI Engineer | PKI | Digital Signatures | IAM | Cryptography | HSM
If you need secure AI solutions, PKI infrastructure, digital signature systems, IAM integration, or cryptography-based applications, youโre in the right place. I am an AI Security Engineer and PKI Specialist with 15+ years of experience building secure enterprise systems for organizations that require strong identity, data protection, compliance, and digital trust. I specialize in combining modern AI technologies with enterprise security practices, including PKI, Digital Signatures, Identity & Access Management, Cryptography, HSM integrations, and secure application development. I help businesses design, build, and improve security-focused solutions that protect sensitive data, secure digital transactions, and support compliance requirements. ๐๐ก๐๐ญ ๐ ๐๐๐ง ๐๐ฎ๐ข๐ฅ๐ ๐ ๐จ๐ซ ๐๐จ๐ฎ ๐๐-๐๐จ๐ฐ๐๐ซ๐๐ ๐๐๐๐ฎ๐ซ๐ ๐๐ฉ๐ฉ๐ฅ๐ข๐๐๐ญ๐ข๐จ๐ง๐ฌ I develop secure AI-powered applications using modern architectures designed for enterprise use cases and sensitive data handling. This includes AI chatbot systems, Retrieval Augmented Generation (RAG) solutions, secure AI assistants, and private knowledge-base AI systems. I also integrate AI into enterprise platforms through secure API-based workflows and backend systems. ๐๐๐ & ๐๐ข๐ ๐ข๐ญ๐๐ฅ ๐๐ข๐ ๐ง๐๐ญ๐ฎ๐ซ๐ ๐๐จ๐ฅ๐ฎ๐ญ๐ข๐จ๐ง๐ฌ I design and implement complete PKI-based systems for secure digital trust and identity verification. This includes Certificate Authorities (CA), Registration Authorities (RA), certificate lifecycle management, certificate issuance and validation, OCSP, TSA integration, and enterprise digital signature platforms. ๐๐ซ๐ฒ๐ฉ๐ญ๐จ๐ ๐ซ๐๐ฉ๐ก๐ฒ & ๐๐๐ ๐๐ง๐ญ๐๐ ๐ซ๐๐ญ๐ข๐จ๐ง I build secure cryptographic systems focused on encryption, decryption, and enterprise key management.
