Systems Engineering: Proven hands-on experience building low-latency, high-performance, and scalable distributed architectures. System Diagnostics: High proficiency in memory management, garbage collection (GC) tuning, performance profiling, and SQL query optimization. Nice-to-Have (Bonus Skills): Financial Domain: Direct familiarity with financial instruments (Equities, Fixed Income, Derivatives). Risk Engine Exposure: Experience building portfolio analytics pipelines, real-time pricing engines, or \"What-If\" scenario calculators. DevOps & Testing: Solid practice of Test-Driven Development (TDD) and CI/CD pipelines.
