Lead AI Engineer
A multi-agent platform that automates legacy code migration, such as moving SQL stored procedures to C#, on codebases of over 100K lines.
- Led a team of 4 building a multi-agent system that migrated legacy code, for example SQL stored procedures to C#, on projects over 100K lines.
- Built a 12-agent system with separate roles under one coordinating agent.
- Had agents pull code context through MCP servers and compare screenshots of the old and new UI through browser automation.
- Ran migrations in parallel on AWS as containers.
Forward Deployed Engineer
A customs platform for UK import declarations. It extracts data from invoices, packing lists and certificates and submits declarations to HMRC for customs brokers.
- Worked directly with UK customs brokers to learn the import declaration process and turned their daily workflow into product decisions and customs rules kept as data, not code.
- Contributed as the main contributor to the first production version.
- Rebuilt the platform as a TypeScript monorepo.
- Built the document extraction pipeline for invoices, packing lists, and certificates using local PDF parsing, vision OCR, and LLM extraction.
- Integrated HMRC CDS submissions and notifications, NCTS transit, IPAFFS, and the UK Trade Tariff API.
- Guarded releases with replay-based validation, automated tests, and browser scenarios filing to the HMRC sandbox.
- Deployed the platform on Azure using AKS and Helm.
R&D
A product feature that automatically splits IT tickets into solvable subtasks using LLM reasoning approaches.
- Automated splitting IT tickets into solvable subtasks.
- Benchmarked CoT, Tree of Thoughts, LATS, ReAct, Reflexion, and multi-agent setups on shared metrics.
- Shipped the best-performing approaches into the product.
A legal search engine built on RAG over 400,000 documents, returning relevant passages and a plain-language answer in 10–15 seconds.
- Built a RAG search engine over 400,000 legal documents that returned relevant passages and a plain-language answer in 10-15 seconds.
An LLM assistant that routes each query to a specialised agent able to run calculations, call pricing APIs, or write and run SQL.
- Built the request router for the xPortal assistant.
- Routed each query type to its own LLM agent that could run calculations, call pricing APIs, or write and run SQL.
A WhatsApp booking agent for a platform serving 700 partner salons and 180,000 active users, taking over appointments previously booked by phone.
- Led a small team that took a WhatsApp booking agent from concept to production for a platform serving 700 partner salons and 180,000 active users.
- Built an agent that booked over 10 appointments a day that used to be handled by phone.
Data Scientist, ML Engineer
Machine learning work including a named entity recognition solution taken to production and model optimisation for faster inference.
- Cut inference time and model size by up to 10x with quantization, pruning, and compilation, without losing accuracy.
- Took a named entity recognition project from concept to production, reaching 98% F1 on the main classes.
R&D Deep Learning Engineer
Research and development of deep learning methods for cardiac MRI, including segmentation, classification and synthetic data generation.
- Worked on 7+ research projects applying deep learning to cardiac MRI.
- Produced patent filings and a first-author journal paper through the research work.
- Built 3 annotation tools for time-series and 4D medical data used to label thousands of samples.
- Applied 2D/3D segmentation, regression on 3D+t MRI, multi-modal classification, GAN-based synthetic data, few-shot learning, and reinforcement learning for landmark detection.
Computer Vision Engineer
An interactive tabletop augmented reality product that combines machine learning and blockchain-based image sourcing.
- Built keypoint regression and object detection on RGB-D streams for a smart lamp.
- Built an automated pipeline for collecting and labelling data.
Intern, Computer Vision and Web Development
Computer vision research on replacing SIFT feature matching in medical images with deep learning.
- Redesigned SIFT feature matching for medical images with deep learning.
- Presented a poster at the EEML summer school.
