Your startup deserves engineers, not contractors

We embed with your team, own the architecture, and ship production systems that scale. Based in Costa Rica, aligned with your timezone.

The problem

Most outsourcing is broken

You send a spec. They send back code. Nobody asked why. The result? Features that ship but don't solve the problem. Architecture that works today and collapses at 10x. Teams that execute tasks but never push back on bad ideas.

We don't do that.

How we work

Engineering means understanding
the problem first

01

We challenge your assumptions

Before writing a line of code, we understand what you're solving and why. We'll push back if your approach won't scale. That's what engineers do.

02

We own the architecture

Event-sourced, reactive microservices on AWS. We don't pick technologies because they're trendy — we pick them because they solve your problem at the right cost.

03

We ship business value

We measure success by outcomes, not story points. Every sprint ends with working software that moves your metrics.

What we do

Three ways to work with us

Build

Reactive Microservices

Full-stack engineering using our open-source Chisel framework, TypeScript, and AWS. Event-sourced systems built for startups that need to scale without re-architecting.

Assemble

Dedicated Teams

We build an engineering team around your problem — not a bench of available developers. Your team, your process, engineers that actually care about your product.

Launch

Startup Ready

Production infrastructure, CI/CD, monitoring — from day one. Move fast with the confidence that your foundation won't crack under growth.

Open Source

We built Chisel so we don't
repeat ourselves

Chisel is our open-source Event Sourcing framework for TypeScript and AWS. It's the foundation of every system we build — battle-tested in production across multiple startups.

We don't just use event sourcing. We wrote the framework. That's the difference between a team that implements patterns and a team that understands them.

AI-Augmented Engineering

We taught AI how to build like us

We've written over 20 custom agent skills that encode our architecture patterns, our frameworks, and our best practices. When our engineers work, AI works alongside them — not as a novelty, but as a multiplier.

Every Chisel bounded context, every CDK stack, every event-sourced microservice — AI knows how we build them. Your project gets the velocity of a team twice its size.

Why Othree

Senior engineers in your timezone, at a fraction of the cost

We're based in San José, Costa Rica. Same timezone as Chicago. A 4-hour flight from most US cities. We speak your language, understand your culture, and overlap with your entire workday.

No midnight standups. No lost-in-translation specs. Just engineers who show up, challenge your thinking, and ship.
