Things I’m building.

Combii

Coordination tools for informal public transport

I founded Combii to help independent minibus drivers coordinate their services and give passengers better information about approaching vehicles. The product combines driver and passenger apps with live vehicle locations, driver-spacing information and group voice messaging.

Its development brought together customer research, field pilots and mobile and cloud engineering. Knowing where neighbouring vehicles are helps drivers manage spacing on routes where they compete for passengers.

Nullsignal

Quantitative trading and autonomous agentic research

I developed Nullsignal as a quantitative trading and autonomous agentic research platform. It combines market-data processing, machine-learning risk models, strategy testing and automated trade execution.

Research agents propose and test improvements within defined budgets and permissions, retaining experiment records and requiring human review before changes reach production.

Trading is the current application. The same approach could support quantitative optimisation in other industries, including insurance and medicine, with domain-specific data, objectives and validation.

Taco Velo

Ordering, planning and inventory software

I co-founded Taco Velo and built the software behind our food-bike business. It covers customer ordering, planning and inventory, including a visual ordering interface designed around the practicalities of serving from a bicycle.

I design, develop and use the system in day-to-day operations, refining it through direct observation and customer feedback. It is software for our own business, shaped by the work it needs to support.
