Michael Orina

Software Engineer / AI Red Teamer

I ship AI-powered products end to end: LLM integration, prompt engineering, and automation pipelines that pair deterministic logic with model reasoning. Off the clock, I red-team frontier LLMs and hunt application-security bugs.

Experience

Software Engineer & Founder @ Datamartics

2026 - Present

  • Built and launched an AI financial assistant on WhatsApp, where users track income and expenses through natural chat and receive AI-generated reports and insights.
  • Designed a hybrid architecture that routes only report generation and media processing to LLMs (Anthropic Claude) while a deterministic classifier handles high-volume parsing, cutting inference cost and latency; built in Go on PostgreSQL and Redis with per-user AES-256 encryption.
  • Engineered structured prompt templates and idempotent, scheduled AI report delivery, with Redis-cached on-demand reports and dry-run tooling to validate model output before send.

Security Research & AI Red Teaming

Independent Security Researcher & AI Red Teamer · 2024 - Present

AI red teaming

Compete in adversarial LLM challenges on Gray Swan Arena, building reproducible jailbreak and prompt-injection chains and mapping failures to the OWASP LLM Top 10.

Bug bounty

Report to enterprise programs on HackerOne, Bugcrowd, and Intigriti; findings include blind SSRF (webhook abuse reaching cloud metadata endpoints) and broken-access-control / BOLA flaws.

Tooling

Built a semi-autonomous hunting workflow with Claude Code, Caido, and browser automation, backed by a reusable skills library.
