Agentic AI · Applied machine learning

AI agents that do real work, and can show how they did it.

I design and ship agentic systems for teams that need them to be reliable, not just impressive. The approach comes from doctoral research in neural networks, years of forecasting under uncertainty, and leading teams that put models into production.

01Focus

Agentic systems, built the way production software is built.

Most agent projects stall between the demo and the second week of real use. The work that closes that gap is mostly unglamorous: scope, grounding, evaluation and clear hand-offs to people.

Agent architecture

Planning, tool use, memory and hand-offs designed around one narrow job at a time. I start from the workflow and the cost of a wrong step, then decide how much autonomy the system has earned.

Grounding and retrieval

Agents that act on your documents and data, not on what a model happens to remember. Every claim and every action can be traced back to the source that justified it.

Evaluation and guardrails

Test suites for behaviour, not just accuracy: task success, tool-call correctness, cost per run, and the failure cases that matter to the business. Measured before launch and watched after.

Human in the loop

Clear points where the agent stops and asks. Approvals, escalation paths and audit logs that let a team trust the system without having to watch it all day.

02Approach

A few rules I hold every system to.

None of them are new. They come from forecasting and research, where a confident wrong answer is the most expensive kind.

  1. Narrow the job before widening the tools.Most failed agents were given too much freedom too early. Scope first, then capability.
  2. Every action leaves a trace.If a step cannot be explained after the fact, it should not be taken automatically.
  3. Measure, then scale.An evaluation harness comes before the second use case, not after the first incident.
  4. Only act when it is worth acting.The idea behind my research on spiking networks: a good system spends a signal only when something is really there.
03Foundation

The agents are new. The discipline underneath them is not.

Time series, then language, then systems that act. The tools changed. The question stayed the same: what is the data actually saying, and how much of it can we honestly stand behind?

Research

Doctoral research in neural networks and time-series forecasting.

Doctoral work on neural networks for forecasting, most recently spiking neural networks: models that fire the way biological neurons do, sparingly and only when something is worth signalling. I have presented that work outside my own field, including to physicists at a statistical physics conference, on what a machine can learn about the shape of short-term memory.

Forecasting

A forecast is an argument, not a guess.

Long before generative AI I was modelling what happens next: demand curves, churn, anomalies buried in years of sensor data. The habit stuck. Systems should state their uncertainty out loud instead of hiding it behind a single number, and agents are no exception.

Language and GenAI

Retrieval, not memorization.

Retrieval-augmented pipelines and language models wired into workflows where a wrong answer has a real cost. Production systems, not demos. This is the ground the agent work stands on.

Leadership

From a rough idea to something a business depends on.

I have led engineering and data science teams through that whole path, translating between what a model can do and what a stakeholder is willing to trust. Roadmaps, not just repositories.
