What we do
One compact team.
One compact team.
End-to-end engineering.
We can own a complete product or strengthen an existing team in the areas where senior engineering matters most.
↗
Web & backend systems
Marketing websites, customer portals, dashboards, APIs, databases and cloud services that work as one product.
Product launch & rescue
Turn an idea into a scoped MVP, modernize a legacy codebase or take a stalled product through release.
Product infrastructure
Authentication, payments, subscriptions, analytics, notifications, third-party integrations and CI/CD.
How we work
Fast enough for a startup.
Fast enough for a startup.

Design the build
We define scope, technical architecture, milestones, dependencies and delivery risks.
Ship in iterations
Regular demos, transparent progress and direct decisions with the engineers doing the work.
Launch & evolve
QA, analytics, infrastructure, App Store / Google Play release and product support after launch.
About the team
Three seniors.
Three seniors.
No agency theatre.
We are three senior software engineers with complementary experience across mobile applications, websites, backend systems and product infrastructure. We have worked on consumer products, subscription apps, complex integrations and products that require years of continuous evolution rather than a one-time launch.
We started this studio to give companies a smaller and more accountable alternative to a traditional agency: direct access to the people building the product, fewer communication layers and senior ownership across the entire delivery cycle.

Capabilities
More than writing screens.
We cover the product layers that usually force a company to coordinate several separate contractors.
Native iOS, Android, Flutter, offline data, push notifications, deep links and store delivery.
Subscriptions, one-time purchases, credits, paywalls, trials, receipt validation and analytics.
APIs, databases, authorization, background jobs, third-party services and scalable infrastructure.
Product websites, customer portals, dashboards, internal tools, CMS and responsive web apps.
Architecture, automated delivery, crash monitoring, performance, security basics and maintainability.
Discovery, scope, estimates, technical roadmap, releases, documentation and ongoing support.
Have a product in mind?
Bring us the idea, the specification or the mess.
We can scope a new product, build it end to end or step into an existing codebase that needs experienced hands.
