Your Senior IT Consultant for complex Backend & Quality projects.
I'm Karim Benna, a freelance IT consultant for backend development, quality assurance and technical project coordination. Since 2017 I've been helping enterprise projects deliver complex software solutions that are stable, transparent and future-proof. Software development, quality assurance and technical coordination from a single source.
What's in here.
What you can expect from working with me.
I help you move your project forward with a clear focus on quality, cost, technical complexity and long-term stability. My commitment is to act in my clients' best interest — even when that means openly addressing risks, weak spots or uncomfortable truths.
Client interests at the centre
I approach technical solutions from the client's goal — pragmatically, transparently, and with an eye on quality, cost and maintainability.
Direct collaboration
You work directly with me as your technical counterpart. That means clear communication, short feedback loops and a shared understanding of what needs to be built.
Experience in enterprise projects
Since 2017 I've been working in complex IT environments — including automotive projects with high demands on quality, processes, alignment and technical stability.
Quality from day one
Quality is not added at the end of a project. I bring experience in E2E testing, test analysis, bug documentation, reviews, CI/CD and stable development processes.
Practical AI know-how
Thanks to my Applied AI & Data Science training, I bring structured AI expertise — from machine learning and deep learning to generative AI, RAG and prompt engineering.
Six areas where I create impact .
Java & Spring Boot Backend
Design and implementation of high-performance microservices and backend architectures with a focus on scalability, security and code quality.
JavaScript, TypeScript & GraphQL
Modern web and backend solutions, including efficient GraphQL APIs built with Apollo and Node.js.
React Native
Cross-platform apps with a native user experience and a maintainable code base.
QA & Test Management
ISTQB Foundation Level certified tester with extensive experience in manual and automated end-to-end testing, test strategy and test process design.
Project Coordination & Product Ownership
Planning, leading and documenting technical projects. Translating business requirements into actionable development tasks. Experienced in agile methods (Scrum, SAFe).
AI Consulting
Consulting on integrating and leveraging AI technologies for process optimisation, automation and decision support.
From first idea to production code.
My process is transparent, fast and adapted to your pace. No unnecessary meetings, no hidden costs – only clear steps towards your goal.
Intro call
30 min video call, free and non-binding. You share your project, I listen and give an honest first impression.
Scope & quote
Clear written outline: what we build, in what timeframe, at what daily rate. No hidden fees.
Delivery
Agile sprints (1–2 weeks), weekly demos, your tool of choice (Jira, Linear, GitHub). I'm part of your team.
Handover & support
Clean documentation, knowledge transfer, optional maintenance contract. You're not left alone.
Engineer by day, athlete on weekends.
Born in Tunisia, educated in Munich, at home between Germany and Portugal. For 9+ years I've been building software for enterprise clients and I'm convinced: "It can't be done" doesn't exist.
„I build software the way a good craftsman works: structured, precise, with attention to detail – and the firm conviction that every problem has a solution."
Notes from the engine room.
JavaScript, TypeScript and the Reality of Complex Software Projects
Personal lessons from automotive projects at BMW – why good software consists not only of working code, but of structure, responsibility, and a team that can handle complexity.
AI in Consulting: Where Language Models Really Help (and Where They Don't)
An honest look at AI integration in consulting projects – beyond the hype.
Backend Development, Spring Boot, and the Reality of Production Cloud Systems
What I've learned from enterprise and automotive projects with Java, Spring Boot, and AWS – why good backends are more than just working APIs, and where configuration details like `spring.jpa.open-in-view` suddenly become critical.
Let's get your project on track.
30 minutes, free of charge, no strings attached. I listen, ask questions and give you an honest assessment – even if I'm not the right partner.
