I research the problem, design the experience, and build the product that removes the friction.

I'm Alan Aranda — a product engineer and designer who owns problems end-to-end. I research the users, design the experience, prototype fast with AI, build production-quality software, ship it to real people, and iterate. Not screens in a file — products in the world.

Self-taught while working full-time as a Royal Mail postman — five products shipped, 1,500+ real users. I learned by building, not in a classroom.

DC Requirements Translator

Helping engineering teams translate complex client requirements into actionable technical specifications.

IndustryData-centre engineering

Problem

Turning a hyperscaler's requirements — rack density, redundancy, cooling — into civil and structural design impacts is slow, manual and easy to get wrong.

Observation

The friction wasn't the maths. It was translating one specialist language — an IT spec — into another: the building.

Outcome

Working MVP, built with a data-centre engineer.

02Marketplace · Discovery

LITTLElocals

Helping parents discover local activities without endless searching.

IndustryParents & families

Problem

Finding something to do with the kids means trawling Facebook groups, council sites and outdated pages.

Observation

The problem wasn't a lack of activities. It was discoverability — and the mental load of the search.

Outcome

Live in Ealing; 0 → 1,500+ users in its first few months.

03Business intelligence · CRM

Referral Intelligence

Helping organisations understand where referrals come from and which relationships generate real business value.

IndustryHealthcare · Business development

Problem

Organisations know referrals matter but can't see which relationships actually generate value.

Observation

The problem wasn't collecting referrals. It was understanding them — turning scattered data into decisions.

Outcome

Live; turns referral data into clear commercial decisions.

04SaaS · Mobile-first

OHNAR

Helping tradespeople quote, invoice and get paid faster.

IndustryTrades

Problem

Tradespeople lose evenings to admin and chasing payments.

Observation

The issue wasn't accounting software. It was the operational friction between finishing a job and getting paid.

Outcome

Live, with early paying customers.

05Internal innovation · Training

Walk Coach

Helping new posties learn delivery walks with less cognitive load.

IndustryPostal operations

Problem

New posties have to hold an entire unfamiliar walk in their head at once.

Observation

The planned fix was a map — but a map is like giving an Uber driver an A–Z. The real problem was cognitive load, not navigation.

Outcome

Working prototype; early conversations with route planners were positive.

Walk Coach is an independent prototype — not affiliated with, or endorsed by, Royal Mail.

Built in months, not years.

2026

Most of these products were researched, designed and launched during 2026 — around full-time work and family life.

Mar 2026

LITTLElocals launched publicly in Ealing.

Spring 2026

LITTLElocals began growing through direct outreach to parents and local activity providers.

May–Jun 2026

OHNAR was built and launched for self-employed tradespeople.

Jul 2026

LITTLElocals passed 1,500 users.

Summer 2026

OHNAR gained its first paying customers.

Summer 2026

Walk Coach, Referral Intelligence and the DC Requirements Translator were created from direct conversations with people living those problems.

How I build

The same method, in any industry

Whatever the industry, the method is the same: watch how the work really happens, find the repetitive thinking and operational friction, and build the software that removes it.

Notice

Spot a problem that other people have quietly accepted as normal.

Ask

Speak directly to the people living it — not around them.

Find the workaround

Understand what they do now: paper, memory, spreadsheets, WhatsApp, improvised systems.

Build the simplest useful version

Not the biggest — the one that changes the behaviour that matters.

Put it in front of real users

Ship it early enough to learn something true.

Learn and improve

Watch what people actually do, then make it better — quickly.

“I build software that removes operational friction — in whatever industry it's hiding.”

Behind the work

Every product came from watching how people actually work — a trade, a parent, a postal round, a data-centre spec, a clinic's referrals — and finding the same thing each time: repetitive thinking and friction that software could remove. Most were built around full-time work and family life: early mornings, late nights, not in perfect conditions.

I use modern AI-assisted tools to move fast from insight to working product — but the judgement, the direction and the decisions are mine.

Now

What I'm working on

LITTLElocals

Live in Ealing — past 1,500 users and growing, adding activities and providers.

OHNAR

Live — getting it in front of more tradespeople and refining from their real jobs.

Referral Intelligence

Live — working with referral-led practices on what to build next.

Walk Coach

Gathering feedback on the prototype and where it could be useful next.

DC Translator

Testing the MVP with a data-centre engineer to see what's most useful.

Updated July 2026.

In their words

People I built with and for

What impressed me most was that Alan didn't jump straight into building a solution. He first spent time understanding our workflow and the challenges we face. The resulting prototype reflected our conversations and showed a thoughtful approach to solving a real business problem.

Ryan A.
Business Development Manager · Referral Intelligence

Alan took the time to understand the operational challenges behind data centre project information before proposing a solution. Rather than making assumptions, he asked the right questions and translated our discussions into a prototype that reflected the workflow we described. I was impressed by how quickly he understood a complex subject outside his own industry and turned it into something practical.
