Summary
👤
Senior🎓
Top SchoolHazem 𓂆 is an experienced Information Technology Consultant and software architect with over a decade of hands-on experience designing scalable Java/Spring systems, SOA platforms, and event-driven architectures that deliver 99.9% uptime. He built and led high-throughput payment and reconciliation platforms for airlines processing hundreds of thousands of transactions daily, drove a zero-regression MongoDB-to-Postgres migration using hexagonal architecture, and scaled throughput tenfold while cutting infrastructure costs. A pragmatic promoter of DDD, TDD, and clean code, he consistently achieves high test coverage, low change-failure rates, and bi-weekly deployment cadence while mentoring teams to measurably improve efficiency. He’s comfortable across the stack—from reactive services and messaging (ActiveMQ, Kafka, Reactor) to serverless patterns—and has a track record of turning operational pain points into automated, reliable systems. Based in Tunis, he balances production-grade architecture by day with experimental side projects by night, keeping a curious, hands-on approach to new technologies.
