About preview
I build products that connect engineering depth with real business impact.
My work sits at the intersection of full-stack product development, cloud architecture, financial operations, workflow automation and data-driven systems.
At Fluna, I helped build and scale financial platforms supporting multi-currency transactions, credit lending, invoice discounting, cashflow forecasting, FX risk mitigation and reconciliation workflows.
Alongside software engineering, my MSc in Sustainable Energy Engineering gives me a strong foundation for energy, climate, infrastructure and technically complex product environments.

Experience
Experience that spans product, platform and operations
I have worked across startup, freelance, charity and enterprise-style environments, building systems where reliability, scalability and business context matter.
Financial platforms
Built fintech systems for multi-currency payments, lending, invoice discounting, reconciliation, FX workflows and secure high-value transaction processing..
Cloud-native systems
Designed scalable backend services using AWS, serverless infrastructure, event-driven architecture and reliable CI/CD pipelines.
Automation and AI workflows
Implemented LLM-powered workflows and process automation to reduce manual effort and improve operational efficiency.
Data and background processing
Engineered high-volume background jobs, batch workflows and migration systems for processing millions of operational records.
Product ownership
Led systems from architecture and implementation through deployment, stakeholder alignment, maintenance and continuous improvement.
Energy systems
A software engineer with an energy systems background
In addition to my software engineering experience, I hold an MSc in Sustainable Energy Engineering with Distinction from the University of Nottingham. My academic thesis focused on sustainable biomass valorisation and optimised biofuel production.
This background helps me bring an engineering mindset to software products that involve complex systems, operational data, sustainability, energy performance or process optimisation.
