AI-FDE · Forward Deployed Engineer

I build AI that ships,learns & grows with you.

Senior AI-FDE at Supernal AI. I work with founders from day one on agents, RAG systems and fine-tuned LLMs, from discovery to deployment to continuous improvement.

Open to conversations with founders building in AI
What I do

I turn founders' ideas into AI products people actually use. Agent architecture, retrieval, evals and fine-tuning, taken from a whiteboard sketch to production, and kept improving after launch.

How I work

From discovery to deployment
to continuous improvement

01 · Discover

Find the real workflow

Sit with CXOs, SMEs and founders to find the work worth automating, then shape it into a product people will use.

02 · Deploy

Ship it to production

Multi-agent systems, RAG, orchestration and tool calling, wired into WhatsApp, CRMs and the back office.

03 · Improve

Make it keep learning

Evals with RAGAS and LLM-as-a-judge, preference alignment and fine-tuning so the system gets better every week.

Experience

Where I've built

Founding teams, startups and big-company data science. The common thread is shipping.

    • Beyond engineering
    • Worked across sales, marketing, product management, finances, market research, business-model canvas and product-market fit.
    • We didn’t reach product-market fit and shut down in the face of well-funded competition, a lesson I carry into every build.
  • Data Scientist

    Autodesk
    Jan ’23 - Jul ’23
    • Employee recommendation product: built an end-to-end internal product that recommends colleagues to connect with based on skills and interest groups.
    • Occupancy forecasting: built an end-to-end time-series algorithm forecasting office occupancy from sensor data across geographies.
    More detail
    • Recommendation product
    • Built multiple recommendation algorithms with AWS Personalize, statistics and SageMaker.
    • Ran the full pipeline myself, from feature engineering to the UI used to demo to stakeholders.
    • Optimised the algorithm by a further 40% and added multiple recommendation filters.
    • Forecasting project
    • Defined the problem statement and engineered features to optimise workspace utilisation.
    • Developed and tested multiple forecasting models with hypothesis testing, plus a custom forecasting feature and stakeholder UI.
    • Delivered a positive financial impact by reducing operating cost and improving space utilisation.

Let's talk

Building something in AI?
I'd love to hear about it.

Whether it's a first agent, a RAG system that needs to be trusted, or a model that needs fine-tuning, drop me a line.
