AI & Web Engineer · Python Instructor
Binacts
- Designed and built an AI security gateway that lets teams use cloud LLMs (GPT-4, Claude, Mistral) without ever exposing personal data to a third-party provider.
- Implemented reversible PII anonymisation by vaulting: detection with Microsoft Presidio and SpaCy, substitution by tokens before the call, and automatic reinjection of the real values from a local vault.
- Added input and output guardrails with LLM Guard — prompt-injection and jailbreak filtering before any LLM call, toxicity screening on the response before it reaches the user.
- Routed calls to multiple LLM providers through LiteLLM behind a single FastAPI interface, with JWT authentication and async SQLAlchemy persistence.
- Built an audit dashboard in React and TypeScript tracking exfiltration attempts and the latency added by the security layer.
- Taught Python and algorithms, guiding learners through exercises, problem solving and code review.
