🔍 Curious about how things work under the hood. I care about the why and how, not just using tools.

🧩 I enjoy solving problems where performance, architecture, and clean engineering matter.

⚙️ Currently: building backend systems & utilities, strengthening my Computer Science & Software Engineering fundamentals, and improving real-world systems through Open Source contributions.

Selected technical contributions across major repositories.

• Microsoft .NET / Runtime — Optimized ImmutableHashSet<T>.SetEquals with comparer-aware fast paths and direct lookups, eliminating unnecessary intermediate allocations and achieving up to ~4,071,000× speedup in specific benchmark scenarios, with zero allocations on compatible paths. (PR #126309)

• Microsoft .NET / Runtime — Optimized ImmutableSortedSet<T>.SetEquals with comparer-aware fast paths and a sequential O(n) comparison instead of per-element O(log n) lookups, achieving up to ~4,681,000× speedup in specific benchmark scenarios, with zero allocations on compatible paths. (PR #126549)

• Microsoft .NET / F# — Optimized Set.intersect for asymmetric set sizes by dynamically selecting traversal direction using tree height, eliminating argument-order performance cliffs and achieving up to 8,000× speedup in specific benchmark scenarios. (PR #19292)

• Microsoft .NET / EF Core — Fixed a memory leak issue in LazyLoaderFactory by replacing strong references with WeakReference, preventing unbounded memory growth and OutOfMemoryException during large-scale data streaming. (PR #37977)

• Microsoft .NET / F# — Fixed assembly signing failures by robustly handling multiple RSA key blob layouts through explicit format validation. (PR #19242)

• Microsoft .NET / VMR (Arcade SDK) — Fixed source-build failures on non-Windows platforms by disabling full assembly signing for non-official builds, resolving RSA+SHA-1 compatibility issues. (PR #5226)

• ✨ Clarity over Complexity
• 🏗️ Fundamentals over Shortcuts
• 📈 Continuous Progress over Quick Wins
