Services
Engineering for teams that outgrow templates and no-code
We help when off-the-shelf tools stop fitting the process — and you need owned software, deep integrations, and a team that can carry it into production.
Cloud & infrastructure
AWS architecture, CI/CD, observability, and scalable backends designed for reliability and straightforward handover.
Integrations & middleware
Connect ERPs, payment systems, compliance APIs, and third-party services with clean, maintainable integration layers.
Web apps & dashboards
Modern frontends for operators, customers, and teams — responsive, accessible, and built to match your product workflow.
How we work
A clear process, no surprises
Small teams, fixed phases, and direct communication with the people writing the code.
01
Discovery & scope
We map your requirements, existing systems, and constraints — then define a clear scope, timeline, and technical approach before any build starts.
02
Architecture & build
A senior team owns backend, frontend, infrastructure, and integrations. You get regular demos, staging access, and documentation throughout.
03
Launch & handover
Production deployment, monitoring setup, and a clean handover — whether you operate it in-house, with us, or with another partner.
About
A Berlin studio for serious software
Portaeu is a boutique software engineering company headquartered in Berlin. We work with companies across Europe and the Middle East — from early-stage founders validating an MVP to established teams modernising operations that have outgrown spreadsheets and off-the-shelf tools.
We're engineers first. That means we care about clean code, reliable infrastructure, and systems that your team can actually maintain after launch — not demos that fall apart under real load.
How we partner
- Small senior teams — no junior bench, no account managers in the middle
- Architecture before features — built to scale, not to rewrite in six months
- EU data residency and GDPR-aware delivery by default
- Long-term partnerships, not one-off vendor relationships
Our products
We also build and operate our own platforms
Beyond client work, we ship production software in regulated industries — compliance middleware, invoicing infrastructure, and multi-tenant SaaS products used by companies in the EU and GCC.
