I'm an Associate Corporate IT Trainer and System & Network Engineer at Balsam Creative Technology, currently building toward Security Engineering as my primary career goal — supported by strong, evidence-based skills in Python Development and Full Stack Development.
My day-to-day role already sits close to the security-adjacent side of IT: I train professionals on hardware & networking, Linux systems, SQL, and enterprise SAP (FICO & MM), and I deliver hands-on troubleshooting across hardware, operating systems, and lab environments. That work is backed by formal networking and systems credentials — CCNA, MCSE, and hands-on VMware experience — which form the infrastructure foundation I'm extending into security engineering: system hardening, network defense, and Linux/Windows administration.
On the development side, I hold a Diploma in Python and Flask Framework, and I build and ship Python and full-stack projects — from a console-based ATM transaction system to API-integrated web apps. I treat this development work as a force-multiplier for security engineering: writing secure code, automating security tooling, and understanding applications from the inside out.
I also founded DevspireHub, and I approach every project — training, infrastructure, or code — with the same habits: clear documentation, systematic troubleshooting, and continuous, self-directed learning.

How Python & Full Stack Development strengthen the Security Engineering path:
- Secure Software Development — Understanding how applications are built (Flask/FastAPI backends, React/Node.js frontends) informs how they should be defended.
- Security Automation — Python is the primary language for writing scanning, monitoring, and response tooling.
- Backend & API Security — Hands-on backend development (Flask, FastAPI, REST APIs) builds direct insight into authentication, authorization, and API attack surfaces.
- Infrastructure Automation — n8n and Python automation experience translates into automating security workflows and DevSecOps pipelines.
Short-term (6–12 months): Deepen Linux/Windows security administration, build Python-based security automation projects, and formalize security engineering knowledge alongside existing CCNA/MCSE credentials.
Mid-term (1–3 years): Move into a Security Engineer / Infrastructure Security Engineer role, applying networking, systems, and Python/full-stack development skills to secure real infrastructure and applications.
Long-term (3+ years): Grow into a Senior Security Engineer / Security Architect role, while continuing to build DevspireHub and AIthon VinLabs and mentoring others transitioning from IT training into engineering.
