ABOUT ME

Java, Php, and C# developer with 7+ years of experience

Professional Summary

I am a Senior Software Engineer and AI Integrator with over 15 years of experience building scalable, mission-critical applications. My career is defined by a unique ability to modernize legacy infrastructure—specifically IBM i (AS/400)—by integrating it with modern Full-Stack and AI/Machine Learning solutions.

Currently, I spearhead AI infrastructure initiatives, where I architect dedicated Linux servers and deploy Large Language Models (LLMs) and TensorFlow environments to drive predictive analytics and interactive demos. Whether it is refactoring decades-old C code into modern C++ frameworks or engineering complex product configurators using Java and ExtJS, I focus on creating high-performance tools that solve real-world business challenges.

Why Hire Me?

Versatile Technical Stack: Expert-level proficiency in Java, C#, Python, C/C++, and RPG, with extensive experience managing SQL, DB2, and Oracle databases.
AI Implementation: Proven track record of hosting production-ready LLM sandboxes and utilizing Gunicorn for concurrent, real-time natural language processing.
Legacy Modernization: I specialize in cross-platform integration, ensuring 99.9% uptime while connecting modern web services to robust back-end systems.
Academic & Mentorship Background: I hold an M.S. in Information Technology and have served as a technical mentor for advanced database systems and algorithmic concepts.

I thrive in environments that require "bridge" thinking—taking the stability of established systems and enhancing them with the speed and intelligence of modern AI.
