Javad Rajabzadeh
Flemish Brabant, Belgium
Summary
🎓
Top SchoolJavad Rajabzadeh is a Senior Software Engineer based in Flemish Brabant, Belgium, with a strong focus on blockchain, microservices, and high-performance distributed systems. Over the past decade he has moved from freelance tooling into senior engineering roles, building consensus and network protocols for Pactus, founding PacViewer (a blockchain explorer), and leading DeFi and smart-contract work at Sensifai. He routinely applies gRPC-driven microservice architectures, concurrent patterns, and MongoDB-backed scalable backends to support real-time processing and high availability. As a hands-on technical leader he reviews protocol proposals, mentors engineers, and bridges R&D with production-grade deployments—an engineer who blends low-level blockchain consensus thinking with product-facing explorer and DeFi features. An often-overlooked strength is his history of building utility tooling and emulators early in his career, which informs pragmatic, operable solutions at scale.
