Michael DiFrancisco

I'm a Senior Software Engineer with seven years of experience building full-stack, data-intensive systems at enterprise scale. Most of my career has been in fintech and financial data, most recently as a technical lead at Mastercard, where I helped build and maintain a Business Intelligence platform serving over 1,000 global clients across billions of transactions.I care about code that holds up under pressure, systems that are secure and correct by design, and teams that get better over time. I've led auth and permissioning initiatives, built CI/CD pipelines from scratch, mentored junior engineers, and owned features end to end from requirements through production.
