I'm a Systems & Backend Engineer focused on low-level software, concurrency primitives, custom memory allocators, and high-performance services. I build backend infrastructure from scratch to understand runtime mechanics, CPU cache behavior, and OS kernel boundaries.
I enjoy the parts of engineering that are easy to underestimate: lock-free designs, protocol layering, database internals, and systems that need to stay correct under real load and pressure.
I'm open to backend, systems, and infrastructure roles where performance, correctness, and low-level understanding matter.
A high-performance database firewall and connection pooler that intercepts PostgreSQL wire protocol messages to block destructive SQL operations and optimize query pipelines with sub-millisecond overhead.
A multi-threaded C++ execution engine built on a lock-free Chase-Lev work-stealing deque and MPSC mailbox architecture. Delivers sub-5µs P50 latency under high thread contention.
A C++ arena allocator featuring custom bump-pointer mechanics, strict CPU cache-line alignment, and zero-fragmentation region resets.
A thread-safe mark-and-sweep garbage collector in C++ featuring VM stack root scanning and automatic heap tracing.
Reduced peak heap usage by 12.5% (6MB) and eliminated GC pressure via module-level static constants for empty JSON bodies.
Expanded metadata and keywords for high-performance NestJS adapters, improving discoverability for features like backpressure handling.
Contributed a fix in qa-agent focused on correctness and edge-case handling in the project’s runtime flow.
Open to backend, systems, and low-level software roles or technical discussions.
