Systems Engineer & Compiler Developer with an engineering background spanning back to the early 2000s.

Combining decades of foundational systems programming — from low-level architectures (x86/x64 Assembly, Win32 API, C) to modern high-performance Python engineering, AOT compilation, asynchronous services, desktop applications, and algorithmic data pipelines.

• Decades of Craft: Writing code since the early 2000s, built on a deep understanding of memory management, operating system internals, CPU microarchitecture, and native Win32/POSIX runtime behavior.
• Hardware-Aware Performance: Bridging high-level Python productivity with bare-metal speed — developing native AOT compilers, custom SIMD (SSE2/AVX2/NEON) vector kernels, FASM x64 assembly engines, and zero-copy C extensions.
• Architectural Discipline: Strong emphasis on clean code separation, strict typing (mypy), modern tooling (uv, ruff), reproducible builds, hardware concurrency, and native assembly compilation (FASM x64).

• Compilers & Low-Level Systems: Python AST to pure x86_64 FASM AOT Compiler, Peephole Optimization, Calling Conventions (Microsoft x64 ABI / System V ABI, 16-byte stack alignment, shadow space), CPU register allocation, hardware atomic primitives (lock add/sub).
• Languages: Python (3.8–3.16, Free-Threaded No-GIL 3.13t–3.16t, PyPy), x86/x64 Assembly (Flat Assembler - FASM / FASMG), C99 / Win32 API
• High-Performance Computing (HPC) & SIMD: SIMD Vectorization (SSE2/AVX2/FMA/ARM NEON), BLAS / GEMM matrix multiplication micro-kernels, SIMD JSON parsing, Vector Search & Embeddings
• Concurrency & Multithreading: True No-GIL Native OS Threads (CreateThread), Free-Threaded Multi-Core (PEP 703), Lock-free & Atomic synchronization, Asyncio, Inter-Process Communication (IPC)
• AI Agents & Protocols: Model Context Protocol (MCP) JSON-RPC 2.0 Servers (Claude Code, Antigravity, Cursor, Windsurf), Agent Trajectory JIT Compilation, Semantic Vector Search
• Desktop & UI Engineering: Modern Fluent Dark UI styling (ui_fluent.inc), High-DPI scaling, CustomTkinter, Flet, Tkinter, native Win32/GDI assembly engineering
• Data, Math & Trading: TA-Lib (quantitative technical analysis & 61 candlestick pattern recognition), OpenPyXL, Pandas, NumPy, SQLite
• Quality & DevTools: uv, ruff, mypy, pytest, Conda-Forge / Rattler-Build, Debian/Ubuntu APT PPA, GitHub Actions CI/CD pipelines
