Experience

Senior Distributed Systems Engineer

Ultra (Remote, B2B) Contract via Genesis Block Advisory

2022 - 2024

Engineered core consensus-layer improvements in a high-performance distributed system handling real-world production traffic. Improved stability and synchronization behavior across multi-node clusters by diagnosing fork conditions and replication inconsistencies. Optimized state-history and execution components to improve throughput under sustained load. Investigated and resolved distributed failure scenarios including network partitions, latency spikes, and inconsistent node state. Contributed to review and integration of low-level C++ changes affecting consensus, replication, and execution layers.

Lead Distributed Systems Engineer (C++)

OTP Bank

2018 - 2022

Designed and implemented a fault-tolerant Replicated State Machine in C++ based directly on the RAFT consensus paper. Implemented leader election, log replication, safety guarantees, and recovery semantics from first principles. Built a secure peer-to-peer networking layer ensuring consistent state propagation across nodes. Ensured strict consistency guarantees suitable for financial-grade transaction systems. Translated formal consensus guarantees into production-ready C++ components with deterministic behavior.

Quantitative Developer (C++ / Python)

Morgan Stanley

2015 - 2018

Translated complex mathematical specifications and pricing models into production-grade C++ libraries. Collaborated closely with Quantitative Researchers to ensure the C++ implementation precisely matched theoretical models. Maintained and refactored legacy codebases to improve readability, stability, and adherence to modern coding standards. Engineered robust backend services to process market data feeds with high reliability.
