I’m a backend engineer focused on building reliable, transaction-heavy systems with strong correctness guarantees.

My work centers on distributed backend services, explicit state modeling, and systems that operate under real-world failure conditions. I care deeply about reliability, observability, and long-term maintainability, and I’m comfortable working across different stacks depending on the problem.

While some of my experience comes from blockchain-adjacent and cryptography-influenced systems, my core strength is backend engineering: designing services that coordinate complex workflows, handle high-value transactions, and remain correct at scale.
