I’m Nicolas, a full-stack developer with a passion for building modern web applications and front-end experiences, and a strong focus on automation, AI and data scraping to help scale businesses through technology.
I build production-grade web applications, marketing websites, internal tools and lead generation systems — usually with TypeScript, Next.js, React, Tailwind CSS and a headless CMS like DatoCMS on the front, Python and MongoDB on the back, and AI integrated wherever it can drive real impact. I care a lot about polished UI, clean architecture, fast iteration cycles and shipping fast without cutting corners.
- PayFit — Originally hired and grew the Growth Engineering team as Lead Growth Engineer, and built Atlas, an internal "gold mining machine" pairing a serverless Python back-end with a React front-end to fuel the sales pipeline across 5 European countries. Now back as a freelance individual contributor, rebuilding the new payfit.com website using Astro + DatoCMS.
- Back Market — Full-Stack Engineer on the B2B division, building pro.backmarket.com with Shopify Hydrogen + Remix, a custom Stripe checkout, multi-seller catalog sync via Algolia, and an automated PDF invoicing system.
- Intigriti — Freelance Full-Stack Engineer building Europe’s leading bug bounty platform’s marketing website intigriti.com and blog from the ground up in Next.js + DatoCMS, with a modular block architecture and Algolia-powered search.
- Alma — Lead Growth Engineer where I rebuilt almapay.com in React + Next.js + Tailwind + DatoCMS, scaled lead generation across a global database of e-commerce merchants with serverless Python, and integrated AI for lead scoring, categorization and risk analysis.
A few iOS and web applications I’ve built end-to-end as a freelance engineer:
- Analog — An iPhone app for vinyl collectors that identifies what’s playing on your turntable and turns your record collection into curated listening sessions. Built with real-time audio recognition and Analog Studio, an AI-powered playlist builder for records you already own.
- goalGetr — An ice hockey training platform helping players track their progress, follow structured drills and level up their game.
- Nucase — A home renovation platform for the Norwegian market, connecting homeowners with contractors and streamlining the renovation process from quote to completion.
- PaperDrop — A fully-featured form builder for PaperDrop’s job management platform, helping UK contractors run their business without paperwork by turning any PDF template into an interactive form completed from the field.
- Smartvatten Solutions Advisor — A sales and lead generation tool for Smartvatten, helping prospects discover the right water management solutions for their building and turning that interest into qualified leads.
I’m open to new client work — whether it’s a web application, a marketing website, a custom internal tool, or a growth engineering challenge that needs solving. Feel free to reach out and I’ll be happy to discuss!
