Services / SaaS applications

Your SaaS product,
built to scale.

I build SaaS applications from idea to launch: clean architecture, accounts and subscriptions, recurring billing and security taken seriously. Made to hold when the number of users grows, not to break on the first real wave.

From me

Sarghy, founder of Sarghy Design

Most SaaS products die from a bad foundation, not from a lack of ideas. Thrown up in a hurry, no architecture, patched until every new feature breaks three others. Then the first serious users arrive and it falls over exactly when it starts working.

I do not put up a demo that looks good to investors and dies in production. I build the foundation properly: clean architecture, code you can keep building on, security and billing done seriously. A product you can grow on, not one you rewrite in a year.

Why it matters

Why the foundation decides whether your SaaS lives

01

A bad foundation catches up with you

A SaaS thrown together works up to a point, and then every new feature turns into a nightmare and the bugs multiply. The technical debt you take on now is paid back far more expensively a few months later, when you also have users you cannot simply switch off.

02

If it does not scale, success kills you

The irony of SaaS: growth is what knocks it over when it was not designed to scale. The users arrive, the app drowns, it goes down exactly when you needed it to hold. Scaling is decided in the architecture; it cannot be patched on afterwards.

03

Security is not optional

A SaaS holds your customers' data. A leak or a broken account is not just a bug — it is trust and the business on the floor. Security goes into the foundation from the start, not bolted on in a hurry once it has already happened.

What I do

What I build, piece by piece

Everything that keeps a SaaS standing, from architecture to billing. One piece at a time.

Architecture & foundation

A structure designed from the start to scale and extend. No patching that drags you backwards the moment you add a feature.

Accounts & multi-user

Authentication, roles, teams, permissions. Who gets in, what they see and what they are allowed to do, set up correctly.

Subscriptions & billing

Plans, recurring subscriptions, automatic invoicing (Stripe and others). The money comes in on its own, without you chasing every payment.

Product development

Your features, built modern and clean. Code you can keep building on, not code to be rewritten in a year.

Security & data

Data protection, access control, security done by the book. You hold your customers' data — and you answer for it, the law included.

Performance & scaling

Optimised to hold under growth. So when the users arrive the app stays up, instead of falling over.

How I work

From an idea to a product you can grow on

  1. 01

    Discovery

    I get to know the product, the users and the business model. What it has to do, who for, and how you make money from it.

  2. 02

    Architecture

    I design the foundation: data, flows, structure. This is where it is decided whether the product scales or breaks.

  3. 03

    Build

    I build in stages, feature by feature. You see the progress as it goes, instead of waiting months in the dark.

  4. 04

    Testing

    I test the critical flows: accounts, payments, security. Anything holding money and data does not go live on trust.

  5. 05

    Launch & growth

    I put the product live and stay on for new features and scaling. A SaaS does not end at launch, that is where it starts.
