I'm building secure firmware and access-controlled AI knowledge platforms.
RomaniaWhat I'm looking for
I'm building security-focused systems at NXP Semiconductors, where I support Hardware Security Engine integration for automotive S32Nxx microcontrollers.
I debug low-level C and assembly on CPU modules using Lauterbach Trace32 environments, automate integration testing through CI/CD, and implement code coverage to support MC/DC quality metrics. I also use LLVM toolchains to compile and optimize C for target processor platforms.
As co-founder of KAIGuide, I lead engineering and architecture for an AI assistant that answers employee questions only from internal company knowledge. I've built a working full-stack RAG MVP with Laravel, React, a Postgres vector store, document ingestion, deterministic role-based routing, and layered safety and access controls; it was accepted into Delta Bootcamp 2026.
My earlier cybersecurity and IT infrastructure training at Romgaz included SOC monitoring, detection, incident response, and Oracle SQL. I also bring networking foundations from Cisco Networking Academy and experience leading training sessions at Logiscool.
Experience
Work history, roles, and key accomplishments
- Hardware Security Engine (HSE) for Automotive Microcontrollers such as S32Nxx
- Integration assistance over third-party software & debugging via LTB T32 environments
- Low level assembly and C debugging on CPU modules
- Automated integration tests via CI/CD pipeline for better validation flow
- Implemented Code Coverage over CPU modules ensuring quality MC/DC metrics
- LLVM toolchains to compile
Co-founder at KAIGuide, an AI assistant for mid-market companies that answers employee questions exclusively from a company's internal knowledge base.
I lead engineering and architecture: building the platform end to end, and making sure that "access control by design" is a real guarantee rather than a tagline. My co-founder owns product and go-to-market.
On the technical side, I've built KAIGui
