Process

How I work with you

Same flow every time — predictable, transparent and quote-locked. No surprises.

  1. 01

    Briefing

    A 30-min discovery call. We define the goal, success metric, scope and budget. I send a fixed quote within 48h.

  2. 02

    Development

    Weekly demo, shared task board, code on GitHub from day one. You see the same progress I do.

  3. 03

    Delivery

    QA on staging, lighthouse + SEO audit, full deploy to production. Documentation + Loom walk-through included.

  4. 04

    Support

    30 days of free post-launch bug fixes and tweaks. Optional monthly retainer afterwards for evolving work.

Testimonials

What clients say

A few words from people I've shipped for over the last 6 years.

Pol shipped our whole FiveM stack — server, NUI in React, Discord bot — in three weeks. We went from 'we want to launch RP' to 200 daily players in a month.
MT
Marc T.
Owner, FiveM RP community
I asked for a landing page. He delivered a landing page + Stripe + admin panel + SEO that already ranks for two long-tail keywords. Fixed quote, on time, no drama.
LG
Lucia G.
Founder, niche e-commerce
Hired him to ship the v1. He owned web, mobile and backend solo and we launched on schedule. Best part: the Lighthouse scores were 100/100/100/100 out of the gate.
DR
Daniel R.
CTO, indie SaaS
His custom Discord bot replaced four off-the-shelf bots and reduced our moderation load by 60%. The payment integration alone has paid for itself ten times over.

FAQ

What people ask the most

Where are you based and what time zone do you work in?

I'm based in Barcelona, Spain (CET / CEST). I work with clients in EU, UK, US East and LATAM. Async is the norm; calls happen 9–19 CET or by appointment for other zones.

How do you charge — hourly or fixed price?

Fixed price per project. I send a quote within 48h of the discovery call. No hourly drift, no scope creep, no surprise invoices.

Do you sign NDAs and IP-transfer contracts?

Yes — both, by default. I sign your NDA before the discovery call and the IP of everything I write transfers to you on final payment.

What's your stack and can you work with mine?

Daily stack: TypeScript, Next.js, Astro, React, Node, Postgres, Prisma, Stripe, Tailwind. I also write C#, Python, PHP and Lua. If your stack is in there, I can plug in; if it isn't, I'll tell you straight if it's worth me joining.

How quickly can you start?

Normally I have a 1–2 week lead time. For urgent rescue work (production down, security issue) I can usually start the same week.
