What I'm looking for

I seek technical leadership roles building secure, on-premise and hybrid infrastructures, working with DevOps practices, containerization, and privacy-preserving AI, in collaborative environments that value mentorship and hands-on engineering.

I am a Lead Full-stack Developer and DevOps Engineer who builds security-first, enterprise-grade infrastructure and applications. I have led a strategic migration from third-party cloud services to on-premise bare-metal infrastructure, implemented containerized DevOps pipelines, and developed ERP, CRM and EMS systems using Laravel and Node.js while integrating Zero Trust networking and on-premise AI microservices.

I also teach STEM part-time, mentoring students in drones, AI/ML, and cybersecurity with hands-on projects and workshops. My background includes backend and frontend engineering, network support, defensive security operations, and projects such as a microservices-based Pixel Enterprise Suite and an open-source OpenSMS Gateway.
