I am a Senior Software Engineer and IT Consultant with over 25 years of experience designing and building enterprise-scale systems across fintech, healthcare, logistics, retail, and education technology. I specialize in fullstack development with React, TypeScript, Java, Python, and Spring Boot, and have strong expertise in cloud platforms (AWS, Azure, GCP), microservices, event-driven systems, and secure payment/identity platforms. In recent years, I’ve also worked on AI/ML and AI-augmented development projects, contributing to model training and evaluation with platforms such as Mercor and Outlier. My career highlights include delivering systems that process millions of monthly transactions at 99.9% uptime, leading global distributed teams, and integrating compliance standards (PCI-DSS, HIPAA, GDPR) into mission-critical applications. I bring a combination of hands-on coding ability, architectural leadership, and adaptability, and I’m passionate about building scalable, user-friendly solutions that power the future of technology.
