Bixen Brown

I’m an AI Systems Engineer and Prompt Specialist with 3+ years building and operating AI-integrated systems, from LLM gateways and prompt frameworks to production automation pipelines. With a BSc Statistics background, I bring statistical rigour to structured data collection, quality control, and end-to-end system documentation.

Since 2022 at BXN (Freelance), I’ve designed and maintained a prompt framework iterated through 35+ versions with measurable quality benchmarks. I evaluate and compare outputs across frontier models (Gemini, GPT-4, Claude, Qwen) using a self-hosted AI gateway stack, and I build AI personas and chat agents using strict anti-hallucination, tone, and formatting protocols.

I also integrate Telegram bots, workflow automation, and inference/evaluation engines into pipelines serving real users. In parallel, I deliver data analysis and reporting as a Data Analyst & Reporting Specialist (2021—Present), producing dashboards and operational summaries with Python, R, and Excel—along with database-backed applications designed for “zero error tolerance.” I’ve further deployed and administered a self-hosted stack of 5+ concurrent services (API gateway, LLM inference engine, workflow automation) on WSL2/Docker, focusing on uptime, security, user access, and clear configuration documentation.
