// INDEPENDENT ENGINEERING LAB

We engineer custom digital platforms from the ground up. Zero no-code stacks. Zero plugin bloat. Pure performance.

Led by Samuel Louissaint, Lead Engineer. We build production web applications, subscription platforms, and bespoke digital infrastructure for founders and businesses worldwide — shipped as source code you own outright.

Section 01 — Selected Works 02 flagship deployments

[01] Platform Engineering / Consumer PWA

Ittsui France一対

An anti-calendar relationship ritual platform, engineered to protect real human connection against schedule decay. One proposal a week, one tap to confirm, and silence in between. The invited party needs no account and no install — the invitation is a plain web link, which is also the product’s entire distribution model. A single TypeScript codebase ships the web app, the installable PWA, and native iOS and Android builds.

Stack: Next.js 14 · React 18 · TypeScript · Tailwind · Firebase / Firestore · Capacitor (iOS / Android) · Stripe · Vercel
Engineering: Passkey authentication (WebAuthn), push notifications, one-tap calendar export, scheduled server cron, graceful three-tier venue fallback
Measured: TTFB 38 ms · FCP 420 ms · load 409 ms

[02] Consumer Platform / Subscription Commerce

Amora Asia

A serious-intent relationship platform for Southeast Asia, built around a verified member directory rather than an endless swipe queue. Custom headless architecture with tiered Stripe billing, image pipeline and identity verification built in-house instead of assembled from plugins — no recurring licence surface, no vendor holding the roadmap hostage.

Stack: Next.js 16 · React · TypeScript · Tailwind v4 · Firebase / Firestore · Stripe Billing · Vercel Blob · PostHog · Vercel Edge
Engineering: Multi-currency subscription ladder, verified-member showcase API with edge revalidation, transactional email on a verified sending domain
Measured: TTFB 38 ms · FCP 324 ms · load 539 ms

Section 02 — Studio Engineering Standards 04 non-negotiables

[01 / Zero No-Code]

You own the source

No Webflow, no Bubble, no Squarespace. Every platform is written in clean, maintainable TypeScript on modern web primitives. You own 100% of the codebase and can hand it to any engineer on earth.

[02 / Sub-Second Performance]

Measured, not asserted

Both deployments above paint in well under half a second from a cold cache — the figures on each card are real measurements, median of three runs, not targets. Zero asset bloat, aggressive edge caching.

[03 / Direct Access]

You talk to the engineer

No account managers, no junior subcontractors, no agency markup. You interface directly with the engineer designing, writing and shipping your codebase.

[04 / Continuous Deployment]

Shipped, not delivered

Full Git hygiene, automated CI/CD, reproducible builds and deployment on modern edge infrastructure. Every change is traceable to a commit and a reason.

Section 03 — Direct Engagement
