What I'm looking for

I am looking for a role that fosters innovation, offers growth opportunities, and values collaboration.

As a Senior Software Engineer with over 18 years of experience, I have honed my skills in designing, building, and scaling distributed systems across various domains, including Financial Technology and decentralized platforms. My expertise in programming languages like Rust, Python, and Java has enabled me to architect complex software solutions that prioritize performance, scalability, and reliability. I thrive in cross-functional teams, mentoring engineers to drive innovation and deliver high-quality software.

Currently, I am a Senior Software Engineer at Nillion, where I contribute as one of the core Rust developers, implementing the Nillion Network. My role involves designing and developing the node storage layer and ensuring seamless deployment processes. Previously, I led a team at Fidelity Investments, architecting a real-time data analytics platform that processes millions of customer events monthly. My experience also includes significant contributions to financial crime investigation software at HSBC, showcasing my ability to tackle complex challenges in high-stakes environments.
