// Sancto Tech · Engineering

MVPs and platforms, in weeks not quarters.

Web apps, SaaS, mobile and internal tools — built by senior engineers on a modern, stable stack. No junior bench, no rebuild after six months. Shipped to production, not "in development".

// what we do

Senior engineering, no bench.

The people who scope your project are the people who write the code. We pick boring, stable tools so your stack outlives your first PM and stays hireable.

Web & SaaS

Next.js + Supabase + Stripe. Multi-tenant ready, performance-budgeted, deployed to the edge from day one. Stable tools that outlive your first hire.

  • Next.js / TypeScript
  • Supabase / Postgres
  • Stripe / billing
  • Edge deploy (Vercel / Cloudflare)

Mobile apps

React Native cross-platform, or native Swift/Kotlin when performance demands it. Same brand and design system as your web. App Store submission included.

  • React Native (cross-platform)
  • Native Swift / Kotlin
  • Push, deep links, in-app purchase
  • App Store + Google Play submission

APIs & integrations

REST and GraphQL APIs, webhooks, third-party integrations (HubSpot, Salesforce, Stripe, Twilio). Auth, rate limiting, monitoring — all production-grade.

  • REST + GraphQL
  • Webhooks & event-driven
  • Third-party integrations
  • Docs (Mintlify / Redoc)

Internal tools

Retool, Supabase Studio, or custom-built. Replace your spreadsheet ops with proper tools that scale past 10 users without falling over.

  • Retool dashboards
  • Custom admin panels
  • Workflow tooling
  • Data exploration
// how we work

Shipped, not in-development.

  1. 01

    Discovery

    One call to find the smallest version that proves the idea and gets you to first users.

  2. 02

    Blueprint

    Architecture, data model, integration map. Reviewed before we write code, so scope doesn't balloon.

  3. 03

    Build sprint

    2–6 week sprints. Live preview every Friday. You click a real product, not a Figma mockup.

  4. 04

    Ship & operate

    Deploy, monitor, document. Retainer or full handover with pairing sessions. Built for handover from day one.

Hospitality · Charter platform

Boka Yachts

Straight answers.

What stack do you use?

Next.js, TypeScript, Supabase, Postgres, Stripe, Tailwind. Modern, stable, and hireable — so when you bring engineering in-house, you can find people who know it.

Can you take over an existing codebase?

Yes. We audit first ($3–5k), map the risks, then propose a path. We won't blindly inherit a mess and pretend it's fine.

Do you do mobile?

React Native by default. Native Swift/Kotlin when performance or platform features demand it. We've shipped to both App Store and Google Play.

What about maintenance after launch?

A retainer (Spark or Studio on the pricing page), or a clean handover with documentation. No lock-in.

How do you hand off to our in-house team later?

Documentation, walkthroughs, pair-programming sessions. We design for handover from day one — no "you'll never understand this code" job security games.

Got an idea that needs to ship in 2026?

30 minutes on a call gets you a tier estimate ±20% and an honest read on scope. No deck required.
