Kernkompetenzen

Wo wir glänzen

01

Systemarchitektur im großen Maßstab

Designing software that handles millions of users — microservices, event-driven pipelines, API contracts, caching layers, and infrastructure that survives growth. Built right the first time.

Microservices Apache Kafka Node.js Symfony / PHP Event-driven architecture Kubernetes REST & gRPC RabbitMQ GCP Google BigQuery Elasticsearch MongoDB CQRS / Event sourcing API gateway Cloud infrastructure BFF architecture GraphQL federation Vue.js
02

Von der Idee zum Produkt — von A bis Z

We've taken dozens of ideas from non-technical founders — a whiteboard sketch, a napkin concept — and turned them into live, revenue-generating software. We speak business first, then code.

Discovery workshops Rapid prototyping MVP delivery Product roadmap

Engineering Leadership

Senior engineering management for growing companies — team structure, hiring, quality standards, and technical roadmap. We bring the experience of having done it before at real scale.

What we offer

Leistungen

01

Engineering Leadership

Senior technical leadership embedded in your team. Architecture decisions, team mentoring, and technical direction — from people who have built at scale before.

02

Technische Due Diligence

For investors and acquirers — an honest, experienced assessment of a codebase, team, and technical risks before you commit capital.

03

Softwareentwicklung

Full-stack web and mobile development with React, Node.js, Laravel, and Python. Microservices, BFF patterns, and GraphQL federation — from greenfield products to modernising legacy systems.

04

Architekturberatung

Reviews, redesigns, and recommendations for systems that need to scale. Kafka event streaming, CQRS, event sourcing, API gateway patterns — or migrating monoliths to microservices.

05

DevOps & infrastructure

CI/CD pipelines, Kubernetes orchestration, containerisation, and cloud setup. So your microservices deploy reliably, scale automatically, and stay up.

06

QA & testing strategy

End-to-end, integration, and performance testing. We set up testing culture and tooling — not just run scripts.

Über e-Streams

Mit Handwerk aufgebaut,
auf Ergebnisse ausgerichtet.

e-Streams was founded in Tirana, Albania in 2005 and has delivered software for clients across five countries over two decades. We've built platforms processing millions of bookings, school systems serving thousands of students, and custom business software for companies that had never had software before.

Today we operate from Cologne, Germany & Tirana, Albania — giving EU clients a trusted European partner with deep technical expertise and the agility to move fast.

Our strongest edge: we take a non-technical client's idea — no specification, no brief, just a problem — and turn it into a live product that actually works at scale.
