About

I build things and put them in front of people.

I am a founder and engineer based in London. I run two live ventures: Fluxr, a scheduling optimisation platform for data centres in power-constrained markets, now live across five markets, and FinLit, a bank-agnostic AI personal finance assistant, live with active users.

My day job is IT Engineer at Odgers, where I manage a hybrid AWS, Azure, and M365 environment spanning EMEA, APAC, and AMER. Internal automation I built there improved ticket handling efficiency by roughly 35%.

Alongside that I build production AI systems end to end: fine-tuned LLMs, RAG pipelines, and cloud-native ML inference platforms on AWS.

Currently pursuing an MSc in Artificial Intelligence at the University of Liverpool and working towards the AWS Machine Learning Associate certification.

Projects

Things I've built.

Live ventures, production AI systems, and infrastructure built end to end.

Fluxr

Live

Scheduling optimisation platform for data centres in high-sun, power-constrained markets. Decides when to run compute workloads so operators burn less diesel and cut emissions. Live across five markets: Lagos, Nairobi, Dubai, Mumbai, and San Francisco, with proxy models filling the gap where nobody else signals well, such as fixed diesel intensity for Lagos and rainfall-modulated hydro for Nairobi.

Pulls solar forecasts, grid carbon intensity, battery state of charge, and electricity pricing into an OR-Tools CP-SAT solver, with XGBoost for solar correction. FastAPI backend on Fly.io, React dashboard on Vercel.

FinLit

Live

Bank-agnostic AI personal finance assistant, live with active users. Ingests transaction data from any UK bank CSV export with auto-categorisation across 20+ spending categories, and includes a compound growth simulator modelling the opportunity cost of spending over 1 to 30 year horizons.

Privacy-first architecture: raw transactions are processed locally and only aggregated summaries are sent to Claude Haiku for insight generation, at approx. £0.11 per user per month. Built with Next.js 14, FastAPI, PostgreSQL, and Docker.

Ticket Triage LLM

Personal project

Classifies free-text IT support tickets into structured, machine-readable output so triage can be automated.

Fine-tuned Qwen2.5-0.5B-Instruct using LoRA adapters on ~800 synthetic samples. Deployed as a FastAPI microservice achieving ~95% schema-valid JSON output compliance.

RAG API Platform

Personal project

A retrieval-augmented generation backend ready to be dropped behind any LLM front-end, with a fully documented REST API and typed request/response contracts.

384-dim SentenceTransformer embeddings, IVFFlat-indexed pgvector store, and cosine similarity top-k retrieval hitting sub-100ms latency.

Cloud-Native ML Inference Platform

In ProgressPersonal project

Production ML inference infrastructure designed for zero-downtime deployments, so models can ship to production continuously without manual release work.

AWS ECS Fargate behind an ALB, full infrastructure-as-code via Terraform, and a CI/CD pipeline through GitHub Actions using AWS OIDC keyless auth, with automatic container image promotion through ECR.
