Experience
Research Engineer, AI Lab
Cracken
UK-based applied AI lab for autonomous security analysis. Remote contract engagement.
- Post-training of open-weight LLMs for the company's autonomous security-analysis product (AI integration, deployment on customer infra): domain-specific abliteration and fine-tuning to raise performance on specialised cybersecurity tasks.
- Co-built RedLineBench (open, MIT): 153 grounded tasks scoring refusal and capability separately, weighted LLM-as-judge rubric, reference run across frontier and open models with two independent judges. Agentic benchmark in preparation.

Senior AI & LLM Engineer
Replika
Owned the rebuild of the conversational engine serving 35M+ global users, coordinating a team of 3.
Architected a hybrid RAG + preference-tuning stack: +40% user retention, +25% dialogue coherence on production metrics.
Cut inference latency by 30% through serving-path optimisation and a lightweight classifier replacing LLM calls, with safety and quality guardrails preserved.
Co-founder & ML Engineer
AndromedAI
Co-founded an AI e-commerce optimisation platform; raised €1.1M pre-seed.
Built an agentic pipeline that rewrites e-commerce product listings at scale, plus cross-encoder product classification at 95%+ accuracy on an open-set taxonomy over 100K+ products.
