  • shipping: parallel platform delivery with predictability, quality and zero hero-dependencies

Live builds

I still ship with my own hands. Both of these are in production — open them.

// concept → production in days, not quarters. That's the bar for "technical fluency".

How I operate

Three principles that show up in every team I've led.

Principle 01

Empathy is the edge

I've worked from a desk in an estate agency and walked construction sites to feel the friction first-hand. Real pain points beat requested features, every time.

Principle 02

Say no early

Blindly copying competitors ends in price-driven competition. I'd rather make the tough call now than ship a roadmap nobody chose.

Principle 03

Mind the cost of inaction

Slipping dates are a tax everyone pays. Thin vertical slices, visible decisions, honest demos — momentum is a product feature.

Where the ethos comes from

My father walked 2,500 miles from Malawi in pursuit of an education, and called his book I Will Try. It turns out to be decent product strategy too: start before conditions are perfect, keep moving, finish.

Legson Kayira, author of I Will Try — proof that the gap between ambition and outcome is closed by shipping.

Always up for talking product
