EXPERIENCE

Freelance Software Developer & AI Specialist 2018 – Present Self-Employed — Remote

• Designed, tested, and iterated prompts for LLM tools across client and personal projects, refining system and instruction prompts to improve reliability, reasoning, and tool-use accuracy.

• Integrated AI into applications using AI APIs and secure API-key management, building working features rather than one-off experiments.

• Taught and mentored individuals on effective AI use, translating complex prompting techniques and LLM behavior into clear, practical guidance — directly transferable to writing prompt guidelines and QA documentation.

• Diagnosed common LLM failure modes (hallucinations, refusals, off-target output) and applied prompt constraints and guardrails to mitigate them.

• Built full-stack web applications (front end and back end) and real-time multiplayer networking systems for clients.

• Performed freelance network and security testing, applying an adversarial, edge-case mindset that maps directly to red-team / adversarial prompt testing and content-safety review.

• Contributed 376+ commits to open-source and personal projects in the past year across multiple languages and domains.

Independent & Small Game Studios

• Developed gameplay systems and tools for multiple small and independent studios, spanning design, implementation, and multiplayer networking.

• Built a real-time multiplayer game engine featuring rollback netcode, server-side anti-cheat, an RPG progression / skill-tree system, and a map editor.

• Directed AI coding agents throughout development, authoring and iterating prompts to steer architecture and catch model errors before they reached production code.

• Validated changes with regression and load/soak testing (including race-condition checks) to prevent quality drift. Earlier Experience 2012 – 2018

• Gas Station Manager (multiple locations) — managed daily operations, staffing, and cash handling.
