Who you are hiring
Vitor Mesquita
Senior Frontend Engineer
I own the frontend so the team moves faster.
Six years inside product teams, across six platforms: Premier League, Tottenham Hotspur, UEFA, LIV Golf, VELUX and Siemens Energy. Most of it on products where a bad deploy is visible to millions of people on a Saturday afternoon.
I ramp up inside your stack and your rituals, then own delivery: architecture, design systems, performance, accessibility, and the small details nobody assigns a ticket to. That has meant a design system shipped across 30+ markets at VELUX, and an enterprise inspection tool built end to end as the only developer at Siemens Energy.
Typed, tested, and documented by default.

How teams bring me in
Pick the shape that fits the role.
Embedded in your team
From
€60/hr
Senior frontend capacity without a hiring cycle. I work inside your repo, your board, and your standups, the way an employee would.
- React, Next.js and TypeScript delivery
- Architecture calls and code review
- Design systems and shared components
- Testing, accessibility and performance
Greenfield builds
A production frontend from an empty repo: architecture, component structure, CI, and the first release.
- Frontend architecture from day one
- Figma to production interfaces
- SSR and API integration
AI product interfaces
The frontend for an AI feature is most of the product. Streaming output, tool and agent state, and the failure cases nobody designs for.
- Streaming and token-level UI
- Agent, tool-call and retry state
- Review and evaluation dashboards
Commerce and product UI
High-traffic surfaces where the frontend is the revenue: checkout flows, dashboards, and multi-market storefronts.
- Checkout and commerce flows
- Headless and Sitecore CMS
- Multi-market delivery, GA4
Working together
From first call to shipping.
Contractor delivery without the agency overhead. Predictable, and written down.
01
A short call
Twenty minutes on the role, the team, the stack and the timeline. No pitch. We both find out whether this is a match.
02
Scope in writing
Contract type, start date, weekly hours and what I am accountable for, agreed before anything is signed.
03
Contract and ramp-up
A straightforward contract, an NDA if you need one, then access to the repo and a fast ramp inside your tools.
04
Delivery in the open
Tickets, PRs, reviews, standups, and a weekly written update. You always know where the work stands.
Before you write
The things you were going to ask.
Are you available right now?
Yes. I am taking on remote frontend contracts across Europe, for contracts of three months or longer.
What does a typical week look like?
I work inside your board and your repo: tickets, pull requests, reviews and standups, plus a short written update at the end of the week so nothing depends on you asking.
Can you work with our existing codebase?
That is most of what I do. I ramp up inside the stack you already have, follow the conventions already in place, and raise the things worth changing rather than rewriting on arrival.
Which stack do you work in?
React, Next.js and TypeScript day to day, with real production experience in Vue, Nuxt and Angular. Design systems, performance and accessibility are part of the job, not extras.
How are you engaged and invoiced?
B2B, invoiced from my own company. I can contract directly with you or through your agency or umbrella company. I am an EU citizen based in Barcelona, so contracting across the EU is straightforward.
What does it cost?
From EUR 60 per hour, with monthly rates for longer contracts. The exact number depends on scope, duration and how much ownership the role carries.
