Technologies

We're not dogmatic about technology. We choose tools that fit your product, team, and constraints. That said, here's what we know well.

Backend

Elixir & Phoenix

Fault-tolerant backends that scale effortlessly.

Python & FastAPI

High-performance APIs with Python's productivity.

Node.js & Elysia

Bun-powered APIs with end-to-end type safety.

Frontend

React & Next.js

Modern web applications that perform.

Vue & Nuxt

Progressive interfaces that grow with your product.

Svelte & SvelteKit

Lightweight apps that ship less JavaScript.

Mobile

React Native

Cross-platform mobile apps that feel native.

Flutter & Dart

Beautiful cross-platform apps from a single codebase.

Database

PostgreSQL

The database that handles anything.

MongoDB

Flexible document storage for evolving data.

Neo4j

Graph database for connected data.

pgvector

Vector search inside PostgreSQL.

DevOps

Docker & Kubernetes

Containerization and orchestration done right.

CI/CD Pipelines

Automated testing and deployment pipelines.

Observability

Monitoring & Alerting

Know what's happening before your users do.

Logging & Tracing

Find the needle in the haystack, fast.

Infrastructure

Cloud Deployment

Get your application to production, reliably.

Database Operations

Keep your database alive, fast, and recoverable.

Secrets Management

API keys, passwords, and tokens - handled properly.

SSL, DNS & Domains

Certificates, domains, and CDN - the invisible foundation.

Incident Response

When production breaks, know exactly what to do.

Compliance & Security

SOC2, GDPR, and security that isn't theater.

Cloud Cost Optimization

Stop overpaying for cloud infrastructure.

Our philosophy

Technology is a means, not an end. We don't use new frameworks because they're exciting - we use what works for your specific situation.

That often means boring, proven technology. PostgreSQL over the latest NoSQL flavor. Server-rendered HTML over complex client-side architecture. Simple deploys over Kubernetes.

When newer technology genuinely solves a problem better, we'll use it. We just don't chase trends.

Have a specific stack in mind?

We're flexible. If you have existing technology choices or constraints, we'll work with them.
