Experience Highlights

Senior Machine Learning Engineer
Jan 2023 - Ongoing3 years 7 months
Project Overview

An AI platform for the UK energy sector supporting automated document processing, regulatory compliance checks, and agentic chatbots for energy-sector clients. The product combines domain-adapted LLMs, LangGraph agentic workflows, and RAG pipelines to ground model outputs in source data, with production ML infrastructure designed for secure, reliable, and cost-efficient operation.

Responsibilities:
  • Led LLM development for the UK energy sector, including LoRA fine-tuning of LLaMA-7B on domain-specific corpora and reduced the domain-specific error rate by 12% against the base model;
  • Designed and shipped specialised LangGraph agentic workflows and tools powering automated document processing, regulatory compliance checks, and agentic chatbots for energy-sector clients;
  • Built retrieval-augmented generation pipelines over domain document corpora, covering embedding generation, vector indexing, retrieval tuning, and prompt design to ground model outputs in source data;
  • Designed and shipped a comprehensive data ingestion and preprocessing pipeline that standardised training-data collection and cut data-preparation cycle time;
  • Served models through FastAPI inference services containerised with Docker and orchestrated on Kubernetes for low-latency, high-throughput production workloads;
  • Owned ML deployment on Google Cloud Platform, including Vertex AI, GKE, and Cloud Run, reducing inference and deployment costs by 35% while maintaining production SLAs;
  • Implemented evaluation, monitoring, and guardrail practices around LLM outputs to keep production behaviour safe, reliable, and auditable;
  • Partnered with product, engineering, and compliance stakeholders to take models from prototype to secure, production-ready systems.
