Why we choose what we choose, not a logo wall

Every technology decision is a trade-off made on purpose. Here's the reasoning, category by category, not a list of names to look credible.

01Languages & Frameworks

What we build with, and why

TypeScript Everywhere It Can Be

A shared type system across frontend, backend, and infrastructure code catches a class of bugs before they reach production, and makes a codebase easier for the next engineer to navigate.

Python for Data & AI

The ecosystem for data pipelines, model orchestration, and ML tooling is deepest in Python — using anything else there means reinventing tooling that already exists and is well-maintained.

React & Next.js for Product Surfaces

Server-rendered React gives fast, SEO-capable interfaces without sacrificing the interactivity modern products need — one framework covers marketing sites, dashboards, and portals alike.

Boring Where Boring Is Correct

A new framework gets adopted when it solves a real problem in front of us, not because it's new. Every dependency we add is a dependency we're responsible for maintaining.

02AI & Models

How we reason about model choice

Model-Agnostic by Default

Foundation models change quickly; the systems we build route around a specific provider so a model upgrade or provider switch doesn't mean a rewrite.

Retrieval Before Fine-Tuning

Most business problems are better served by giving a model the right context at query time than by retraining it — cheaper, faster to iterate, and easier to keep current.

Evaluation Is Part of the Build

A model integration ships with an evaluation set built from realistic inputs, not a spot-check before launch — the same standard we hold any production code to.

Open and Closed Models, Chosen Per Task

Some workloads are better served by a smaller, self-hosted model for cost or latency reasons; others need a frontier model's reasoning. We choose per workload, not by default preference.

03Data & Storage

Where the data actually lives

PostgreSQL as the Default System of Record

A mature, well-understood relational database is the right foundation for most transactional systems — reached for first, not replaced by something more novel without a specific reason.

Purpose-Built Stores Where They Earn Their Keep

Redis for cache and ephemeral state, vector databases for retrieval, message queues for asynchronous work — each addition solves a specific access pattern the default store handles poorly.

Schema and Migrations as Code

Data structure changes are reviewed, versioned, and reversible — the same discipline applied to application code applies to how the data underneath it evolves.

04Cloud & Infrastructure

How systems get deployed and run

Containers as the Deployment Unit

Packaging an application the same way for every environment — local, staging, production — removes an entire class of ‘works on my machine’ failures.

Infrastructure as Code, Reviewed Like Code

Environments are defined in version-controlled configuration, not clicked together in a console, so an infrastructure change goes through the same review as an application change.

Cloud-Provider Fit Over Default Preference

AWS, Google Cloud, or another provider — the choice follows your existing footprint, compliance needs, and cost profile, not a standing preference on our side.

05Security

Built in, not bolted on

Secure by Design

Identity, access control, and encryption are part of the architecture from day one, not a hardening pass before launch.

Access Control

Least-privilege access and audit logging on every system we build, so who touched what is never a mystery.

Encryption Everywhere

Data encrypted in transit and at rest as a default, not an optional configuration.

Responsible Disclosure

A clear, monitored channel for reporting vulnerabilities — see our Security policy for details.

06Delivery

How change ships safely

CI/CD as Standard

Every change ships through the same automated pipeline — build, test, deploy — not manual copy to production.

Staged Rollouts

Changes move through environments deliberately, with the ability to catch a problem before it reaches every user.

Observability from Day One

Logging, monitoring, and alerting are part of the initial build, not a project added after the first incident.

Rollback Ready

Every deployment is designed to be reversible — a bad release is a delay, not a crisis.
