01 — Work

Selected work.

“A few products I built solo, from an empty repo to production. Each one is real, live, and shaped around its users’ needs.”

Cybersecurity

An incident, a doubt, a vulnerability?

I help individuals and businesses respond to incidents, uncover scams, assess systems and strengthen their security for the long term.

The conviction

A prototype
impresses.
A v1 has to survive
its first real user.


That is the only version I build — the one a founder can put in front of an investor, or a real customer, without flinching.

02 — Process

How I work.

« Four steps, fixed scope, price agreed upfront. No hourly billing, no black box, no surprises. »

  1. Step 01

    Scope call

    20 minutes, free. We figure out what you want to ship, for whom, and by when. If I’m the wrong person, I’ll say so.

  2. Step 02

    Fixed-fee proposal

    Within 48h. Scope, deliverables, one fixed fee agreed upfront, dated milestones. No "starting at".

  3. Step 03

    Delivery sprint

    4 to 6 weeks. A Friday demo every week on a Vercel preview. You watch the product grow live — no black box.

  4. Step 04

    Hand-off + 30 days

    You leave with the repo, the accounts, the pipeline. One month of 24h replies. Beyond that: a fresh fixed-fee scope.

Danilson Ramos — développeur web full-stack et designer produit à Zürich, Suisse

« Ten years writing software, five pairing it with design. Portuguese by heritage, French by birth, Swiss by address — I work out of Zürich, Switzerland, mostly with founders shipping their first product. »

A full-stack web developer, I build the v1 most agencies subcontract. End to end: positioning, design system, Next.js codebase, Postgres schema, billing, transactional email, deploy pipeline. Fixed-scope sprints, one fixed fee.

I don’t subcontract. I don’t ship Figma without code, or code without design review. When the data model is shaky, I rewrite it in week two so you don’t pay for it in week ten.

FAQ

Frequently asked questions.

  • What does a full-stack web developer like Danilson Ramos do?

    I cover the whole chain of a SaaS product: positioning, design system, interface, front-end and back-end code, Postgres database, payments, transactional email and deployment. One person, from an empty repo to a product that is live.

  • How much does it cost to build a SaaS v1?

    Fixed-fee: one price, agreed upfront after the scope call. No hourly billing, no "starting at". You know the amount and the dated milestones before you sign.

  • How long does it take to build the first version of a product?

    A delivery sprint runs 4 to 6 weeks, with a demo every Friday on a Vercel preview. You watch the product grow live — no black box.

  • Do you work with founders across Switzerland?

    Yes. I am based in Zürich and work with founders across Switzerland and Europe, in French and English. The work is remote, with a weekly check-in.

  • What is the difference between a prototype and a v1?

    A prototype impresses in a demo; a v1 has to survive its first real customer. I only build the v1 — the version a founder can put in front of an investor or a real user without flinching.

  • What technologies do you use to build a SaaS?

    Default stack: Next.js, TypeScript, Tailwind, PostgreSQL and Vercel. Also fluent in Python, SQLite, Stripe and Resend depending on what the product needs.

  • Are you available for a new project?

    I take one to two projects per quarter to stay focused. The simplest way in is an email to danilson.daveigaramos.pro@gmail.com — reply within 24h, Mon–Fri.

Build School

Learn to build a SaaS like a real product.

The same method I use to ship v1s — condensed into a hands-on course, from an empty repo to a product online.
