Client feedback
“Ray has been a very important partner in setting up our analysis tools. He developed code to interpret unstructured data using generative AI, which substantially improved our capabilities in natural language processing. He has always been very responsive and always delivered by the deadline, which was frequently quite tight.”
“Since Ray built my website, I've been getting clients from all over the world — exactly what I wanted. Communication was clear and delivery was on time.”

About
Big-company engineering, small-business attention.
Hi, I'm Ray — a software engineer based in Liverpool with 5+ years of experience. I've spent my career building the systems behind fintech and payment platforms: software that handles thousands of transactions every day and can't afford to fail.
I started Lunowisky to bring that same quality to small businesses, without agency prices or jargon. You work directly with me, from the first call to launch and beyond.
I speak both English and Portuguese, so Brazilian businesses in the UK can talk through their project in whichever language feels most natural.
Tools I work with
FAQ
Questions, answered.
How much does a project cost?
Every project gets a fixed price after a free consultation, so you know the full cost before anything starts. There are options for every budget, from a simple landing page to a complete custom app.
How long does it take?
A landing page usually takes 5–7 days and a business website 2–4 weeks. Apps and AI projects vary, and you get a clear timeline in your proposal.
Do you only work with businesses in Liverpool?
I'm based in Liverpool and happy to meet locally, but I work with businesses across the UK. Everything can be done remotely.
Can we talk in Portuguese?
Sim! I work in both English and Portuguese, so Brazilian businesses in the UK can discuss their project in whichever language they prefer.
Do I need technical knowledge?
Not at all. I explain everything in plain language, handle the technical side, and show you how to use what I build.
Who owns the website or app?
You do. Once the project is paid for, the website, code and content belong to your business.
What happens after launch?
You can take over yourself, or choose a care plan where I look after hosting, updates, backups and small changes each month.
