Engineering & Development

Production software, built to last.

Full-stack web, SaaS, mobile, and commerce — on a modern TypeScript stack with performance budgets, CI/CD, and scalable infrastructure from day one. We build for the version of your product that has real users.

Approach

We don't ship prototypes and call them products.

Anyone can stand up a demo. Shipping software that stays fast under load, survives a team growing around it, and doesn't rot after launch is the hard part — and it's what we do. Typed end to end, tested, observable, and deployed through CI/CD. The infrastructure is scalable from the first commit, not retrofitted after the fire.

What we do

Five ways we build.

Full-Stack Web Development

Fast, modern web applications on Next.js, React, TypeScript, and Node.js. SSR/ISR architectures for speed and SEO, with Core Web Vitals optimization built into the delivery, not bolted on after.

A typed, performant, SEO-ready web app your team can extend.

SaaS & Web Application Development

Software built to be sold. Multi-tenant architecture, role-based access control, API-first design (REST/GraphQL), and CI/CD pipelines — the foundations a real SaaS business needs.

A secure, multi-tenant platform with the access control and APIs to scale.

Cross-Platform Mobile Development

One codebase, both platforms, native where it counts. React Native or Flutter with native module integration and over-the-air (OTA) deployment for fast, controlled updates.

iOS + Android from a shared codebase, with native performance where it matters.

Shopify & Headless Commerce

Storefronts that convert and scale. Hydrogen/Storefront API headless builds, custom Shopify app development, and ERP/CRM integrations that connect commerce to the rest of your business.

A fast, custom commerce experience wired into your operational systems.

MVP & 0→1 Product Engineering

From idea to a product that can actually grow. Rapid prototyping through to production-grade builds — with scalable infrastructure from day one, so your MVP isn't a rewrite waiting to happen.

A real product in market fast, on foundations that won't need ripping out.

How we work

Scoped, shipped, and observable.

Step 01

Architecture

Data model, APIs, infra, and performance budget defined up front.

1Step

Step 02

Build in slices

Vertical slices shipped behind CI/CD, reviewed continuously.

2Step

Step 03

Harden

Tests, monitoring, and Core Web Vitals before launch.

3Step

Step 04

Deploy & hand over

Production deploy, docs, and clean ownership transfer.

Fit

Who it's for.

Founders who need an MVP that won't need a rewrite at Series A.
SaaS companies scaling from single-tenant to multi-tenant.
Teams that need mobile without doubling their engineering.
Commerce brands outgrowing off-the-shelf Shopify themes.

Engineering deliverables

What we hand over when the build ships.

CI/CD from commit 1

Automated tests + preview envs + prod deploys on your GitHub.

Core Web Vitals green

Performance budgets enforced. LCP, CLS, INP all pass.

Tests + observability

Unit + integration tests, plus logs / metrics / traces in prod.

Docs + runbooks

How to run it, deploy it, debug it. Everything on your wiki.
