Technologies
We work with a small set of technologies, so that we deliver quickly and can maintain what we have delivered. The radar shows what we build with today and what we are evaluating now. The list below it explains what we use each technology for.

Languages and frameworks
I- 01
TypeScript
StandardThe language of all our code, from interfaces to infrastructure scripts. Types catch errors before delivery and keep projects easy to maintain.
- 02
React
StandardThe foundation of our interfaces, rendered on the server for pages that load fast the first time. The same library covers web and mobile.
- 03
React Router
StandardThe framework of our web applications: routing, data loading and server rendering in one system. This site runs on it.
- 04
React Native
StandardApplications for iOS and Android from a single codebase, published and kept up to date in both app stores.
- 05
Go
EvaluatingA compiled language for network services and command-line tools. We are evaluating it for the components where fast startup and a small footprint matter.
Cloud and infrastructure
II- 06
Cloudflare Workers
StandardThe platform our applications run on: code executed close to users, with no servers to manage and costs that grow only with use.
- 07
Cloudflare D1
StandardThe SQL database of our applications on Workers: managed SQLite with automatic backups.
- 08
Cloudflare R2
StandardObject storage for files, images and documents, S3-compatible and with no egress fees.
- 09
AWS Lambda
StandardServerless functions for event-driven processing and integrations between systems, designed around actual usage and budget.
- 10
AWS S3
StandardOur default object storage for files, archives and project data, with access rules, versioning and predictable costs.
- 11
AWS DynamoDB
StandardA managed NoSQL database for large volumes with constant latency at any scale, paid per use.
- 12
AWS Aurora DSQL
StandardThe serverless SQL database from AWS, PostgreSQL-compatible, distributed across regions and scaled automatically with traffic. We use it where a client's data has to stay in their own AWS account.
- 13
AWS Neptune
EvaluatingA managed graph database. We are evaluating it for data with complex relationships, where queries across relationships outperform relational tables.
- 14
Neon
EvaluatingServerless PostgreSQL, with database branches created on demand for every environment. We are evaluating it for projects that need Postgres without infrastructure administration.
Platforms and data
III- 15
Shopify
StandardThe platform of the online stores we build and operate: catalog, payments, shipping and invoicing in one system.
- 16
Hydrogen
StandardThe Shopify framework for custom storefronts, rendered on the server. The Instrumente Creative store runs on it.
- 17
Payload
StandardThe content management system inside our applications: editors work in clear interfaces, and the data stays in the project database.
- 18
PostgreSQL
StandardOur default relational database for data that needs complex queries. With the pgvector extension it also serves as the basis for semantic search in our AI projects.
Artificial intelligence
IV- 19
Model Context Protocol
StandardThe standard through which we connect client systems to AI assistants: documented MCP servers with clear permissions and an audit log.
- 20
AWS Bedrock
StandardModel access through AWS infrastructure, for projects where the data has to stay in the client's cloud account.
- 21
OpenRouter
StandardA single access point to several model providers, with cost control and model switching without code changes.
- 22
Kong AI Gateway
StandardA gateway for the AI traffic of larger systems: limits, logging and rules about which data reaches which model, enforced at the infrastructure level.
