I’m a full-stack software engineer who builds responsive, data-driven applications with a strong focus on clean, maintainable code and real-world performance. Over the past several years, I’ve worked across React and Next.js front ends and Django/Python back ends, creating scalable REST APIs and polished user interfaces that feel fast, accessible, and reliable. I also bring DevOps and cloud-practice experience to my work—containerizing services with Docker, setting up secure server environments on Ubuntu, and optimizing caching and deployment flows. I enjoy using AI-assisted development tools (like Claude, Cursor, and ChatGPT) to speed up debugging and iteration while keeping engineering standards high through testing, code reviews, and agile sprint delivery.

Software Engineer / Code Repair Annotator at Mercor – Remote
August 20, 2026 - Present
Diagnosed and repaired incremental billing rollup regressions, optimizing cache invalidation, reuse, and bounded eviction to eliminate redundant scans and improve incremental and full recomputation correctness. Traced complex state and caching interactions across an existing billing engine, implementing constrained target fixes and validating results against correctness and performance benchmarks. Repaired an inline-cache regression in the Lumen runtime by tracing compiler bytecode execution through VM cache site handling, correcting cache site indexing, and implementing dynamic cache growth when programs exceeded initial cache capacity. Corrected object-shape transition and field-mutation behavior to preserve inline-cache validity across attribute updates, deletion/re-addition, prototype shadowing, and polymorphic access patterns. Validated the Lumen repair against documented benchmark workloads with all visible workload passing documented operation budgets.
