Case studies:
problem, solution, result.

Case studies of two web apps our team built, both live today: for each one we walk through the client's problem, the technical choices and the numbers that came out. Valeureux's platform, built for a French investment fund, manages €4M+ in assets; BLOCKv's dashboard streams 3M+ on-chain transactions in real time. Every other project, in short, is in the portfolio's website design ideas.

Valeureux: investor platform

An all-in-one web app for a French investment fund: KYC/KYB onboarding, live investment opportunities and embedded contract signing, with per-user admin control over what each investor sees and the fees they pay. Today it manages €4M+ in assets across various vehicles.

BLOCKv: real-time dashboard

A Web3 dashboard that scrapes and enriches 3M+ on-chain transactions and streams them live over SSE, keeping every query a visitor waits on near-instant: a ~16 ms live feed at a 99% cache hit rate, and a perfect 100/100 on accessibility, best practices and SEO.

Questions about our case studies.

Each case study follows one project from start to finish: the client's problem, the first technical calls, how we worked, who worked on it and the numbers measured at the end. Enrico, who worked on both projects, wrote them, and they also cover the choices changed along the way, such as BLOCKv's move from TimescaleDB to Supabase to cut costs.
Our team built them before NFW Web Studio existed: Enrico and Samuele developed Valeureux's platform, with in-house web design based on the client's colors and fonts; Enrico alone built BLOCKv's dashboard, on an external design. Each case study says so in its Team section.
Valeureux's platform manages €4M+ in assets for around 150 investors worldwide, most of them in France. BLOCKv's dashboard works on 3M+ on-chain transactions: the live feed responds in about 16 ms at a 99% cache hit rate, queries on critical paths stay under 100 ms, and Lighthouse scores 100/100 on accessibility, best practices and SEO.
Both have a Next.js frontend on Vercel and a Postgres database on Supabase. Valeureux uses Directus as the admin CMS; BLOCKv uses a scraper written in Bun on a Hetzner VPS, replica servers that stream data live over Server-Sent Events, and a backend that handles caching.
A web app like these, with log-in, permissions, dashboards or a CMS, gets a custom quote: it has no list price because it depends on the features you need. It starts with a free 30 minute call, and the written quote arrives within 24 hours. Website and landing page prices are published on the pricing page.
