You work with the people who build it
No account layer between you and the engineers. The person in your kick-off call is the person writing the code, for the whole project.
6 people — Rome
Team
Six people: four engineers, a researcher and a designer. Small enough that everyone knows every project, senior enough that nobody needs supervising.
How we work with clients
Senior only, no bench
Everyone here has shipped production systems for a decade or more. We do not staff projects with juniors learning on your budget.
Three projects at a time, maximum
Which means the calendar matters. If you need something delivered this quarter, start the conversation before the quarter does.
Team
6 peopleProduct & Frontend
Renna Voss
Founder & Principal Engineer
Fifteen years building software for people who did not choose it. Previously led engineering at a logistics platform through 4x headcount. Founded Intervia in 2019.
- TypeScript
- React
- Next.js
- Product strategy
Platform & APIs
Idris Kalu
Principal Engineer
Writes the unglamorous code that keeps working. Cares more about the 95th percentile than the demo, and will argue about database indexes for longer than is polite.
- Go
- PostgreSQL
- Kafka
- API design
Discovery & UX Research
Ma Sun-ho
Head of Research
Trained as an ethnographer, now applies it to clinical and industrial software. Has sat through more shift handovers than anyone should have to.
- Field research
- Service design
- Usability testing
Cloud & DevOps
Bea Lindqvist
Staff Engineer
Takes monoliths apart without taking them down. Believes a migration you cannot roll back is not a plan, and that deploys should be too boring to remember.
- Terraform
- Kubernetes
- AWS
- Observability
Interface & Design Systems
Théo Marchand
Lead Product Designer
Designs the dense screens first. Comes from a data-visualisation background, which shows up in an unusual tolerance for tables.
- Design systems
- Interaction design
- Accessibility
Quality & Testing
Nadia Haddad
QA & Reliability Lead
Finds the edge case in your happy path. Builds the test suites that let a small team ship on a Friday without regretting it.
- Playwright
- Load testing
- CI pipelines
Working here
HIRING SELECTIVELYWe hire rarely and slowly. When we do, we are looking for engineers who have maintained something for years rather than launched a lot of things once — the instincts are different.
No open roles right now. If that changes it will be listed here first. You are welcome to write anyway; we keep good letters on file and we do reply.

You will get an engineer on the call, not a salesperson. Tell us roughly what you are trying to do and we will tell you whether we can help.
