Summary
🤩
Rockstar🎓
Top SchoolRikard Pavelic is a Chief Architect with 14 years of software engineering experience, currently leading the design of a high-performance, maintainable core banking system at Oradian. He leverages a deep expertise in DSL-driven architectures—both as the "brains behind DSL Platform" and through substantial contributions to high-performance JVM projects like dsl-json and the TechEmpower benchmarks. Rikard has a proven track record improving database and serialization stacks, evidenced by work on the PostgreSQL JDBC driver and benchmarking integrations for FlatBuffers and Cap'n Proto. As owner of a software consultancy and a former R&D developer, he blends hands-on implementation, tooling/annotation-processing know-how, and operational concerns to ship robust systems. Based in Zagreb with a computer science master's from FER, he quietly balances product-level architecture with low-level performance tuning and build/deployment automation.
