Full Stack Developer
I am a Full Stack & AI Engineer with over 20 years of experience building resilient, enterprise-scale software and solving complex architectural challenges. My expertise spans the entire lifecycle of software development, from managing high-stakes legacy migrations to engineering modern production-grade Artificial Intelligence (AI) and Machine Learning (ML) systems. I specialize in designing and deploying intelligent automation frameworks, utilizing advanced LLM-based Agents for autonomous decision-making and orchestrating workflows via the Model Context Protocol (MCP) to seamlessly bridge the gap between AI models and secure data sources. I prioritize sound technical decisions that balance cutting-edge performance with long-term maintainability, remaining highly adaptable when integrating emerging technologies or pivoting to meet shifting business requirements. A proven track record of delivering measurable results, I have consistently driven significant operational savings and achieved zero-downtime deployments in high-availability environments.
