About

Senior-Led Engineering. No Exceptions.

Bunshin was built around a single structural commitment: the people who scope your work are the people who build it. The standard that holds in a nuclear control room holds in a sprint review. That is not a value statement. It is how we operate.

Rafael Bejaran

Director of Operations & Strategy

B.S. Business AdministrationPMP®CSM®

Rafael spent his Navy career being the person accountable when complex systems failed and the stakes were real — from safety-of-flight radar suites on aircraft carriers to fleet-wide operational readiness across the 2nd, 5th, and 7th Fleets. That standard carried directly into delivery leadership on high-concurrency, high-availability consumer platforms. PMP® and CSM® certified. At Bunshin, he owns client relationships, project governance, delivery timelines, and business development — the same person who scoped your engagement is the one accountable for delivering it.

Jose Diaz

Director of Technology & Architecture

B.S. Mathematical Sciences, Penn State.NET 8AzureAWS

Jose has delivered production systems at AT&T, Assurant, Talen Energy / Susquehanna Nuclear Power Plant, and Jefferson Health — nearly 15 years of engineering across national telecommunications, enterprise insurance, nuclear energy, and healthcare. The work ranged from systems integration at AT&T scale to a 100% HIPAA-compliant health records migration to cloud at Jefferson Health, with nuclear facility software in between.

Compliance-grade engineering is the baseline, not an upgrade — a standard developed working directly inside environments where there is no margin for error. His technical depth spans .NET 8, C#, ASP.NET, Angular, Azure, AWS, and Docker.

At Bunshin, Jose leads all technical architecture, code quality standards, cloud infrastructure, and security posture. Every line of production code passes through his review.
