About Me
Senior Software Engineer, AI Specialist & Microsoft 365 Consultant with 10+ years' experience designing, building, and scaling enterprise SaaS platforms across healthcare, finance, and legal tech. I specialize in full-stack development (React, Node.js), cloud architecture on Azure, and Microsoft 365 consulting—with a focus on custom SharePoint SaaS solutions for the legal industry.
At Altera Digital Health, I modernized legacy systems into microservices, improving uptime and deployment speed by 40%. More recently, I've delivered legal-tech-focused SharePoint workflows that streamline case management, document automation, and compliance tracking, empowering legal teams to operate securely and efficiently.
I'm passionate about applied AI—from deploying NLP-driven chatbots to embedding AI-powered document intelligence in Microsoft 365 environments. Alongside technical delivery, I thrive on mentoring engineers, collaborating with cross-functional teams, and turning complex legal and regulatory requirements into secure, scalable SaaS solutions.
