Software Engineer & Systems 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, 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, and native Win32/POSIX runtime behavior.
• Hardware-Aware Performance: Bridging high-level Python productivity with bare-metal speed — leveraging custom SIMD SSE2 vectorized math kernels, FASM assembly, and zero-copy C extensions.
• Architectural Discipline: Strong emphasis on clean code separation, strict typing (mypy), modern tooling (uv, ruff), reproducible builds, and native assembly compilation (FASM x64).

• Languages: Python (3.8–3.16, Free-Threaded No-GIL 3.13t–3.16t, PyPy), x86/x64 Assembly (FASM), C / Win32 API
• AI Agents & Protocols: Model Context Protocol (MCP) JSON-RPC 2.0 Servers (Claude Code, Antigravity, Cursor, Windsurf), Trajectory JIT Compilation, Vector Search
• Concurrency & Internals: Asyncio, Free-Threaded Multi-Core (PEP 703), SIMD Vectorization (SSE2/AVX2/FMA/NEON), ctypes & C FFI, Inter-Process Communication (IPC)
• Desktop & UI Engineering: CustomTkinter, Flet, Tkinter, ttkbootstrap, High-DPI scaling, Native Win32/FASM x64 engineering
• Data, Math & Trading: OpenPyXL, Pandas, TA-Lib (technical analysis & pattern recognition), NumPy, SQLite
• Web, Scraping & Automation: Playwright, Requests, cURL-cffi, Pydantic, REST APIs, Session & Auth management
• Quality & DevTools: uv, ruff, mypy, pytest, Conda-Forge / Rattler-Build, Debian/Ubuntu APT PPA, GitHub Actions CI/CD
