THE REALITY CHECK

Does this sound familiar?

Fear of deployment

You dread releasing new features because every deployment feels like a gamble. Bugs appear faster than solutions, and your team is stuck fixing instead of building.

The legacy trap

You have a profitable Ruby on Rails system, but you're afraid to touch it because 'everything might collapse'. You feel held hostage by your own code.

Cloud waste & anxiety

Your cloud bills are spiraling, and no one knows exactly what's running. You worry about security holes and paying for resources you don't need.

The leadership vacuum

Your developers are writing code, but no one is designing the future. You lack a technical partner to challenge ideas and prevent expensive architectural mistakes.

You don't need more "hands on keyboards." You need a partner who takes the wheel.

OUR ENGAGEMENT MODEL

We Don't Just "Rent Coders". We take ownership.

WHO WE ARE

Technical authority & Team

We are a tight-knit unit of 15 senior engineers, not a "body shop" agency. We don't hire juniors for critical projects. We specialize in stabilizing complex Ruby ecosystems and Cloud infrastructure. We thrive where others say "this is impossible."

Our core values

Uncompromised honesty

We prioritize your long-term success over short-term comfort. If a feature creates technical debt or wastes budget, we will tell you directly before you spend a dime.

Pragmatic engineering

We don't chase trends. We deploy proven, stable technologies perfectly matched to your business stage. Your architecture must support growth, not ego.

Outcome over output

We measure success by features shipped and problems solved, not by lines of code written. You pay for results, not just for effort.

Let's stabilize your business.
