Mikael Cratz
Developer with deep knowledge in several programming languages.
Turning complex problems into clean, maintainable code.
01 - ABOUT ME
With over 15 years of experience in C and C++, I have built
and maintained software for embedded and system-level environments, developing a strong
foundation in performance, reliability and clean architecture.
Today, I combine that technical depth with modern
fullstack development in C#, ASP.NET and Azure, alongside extensive work with WPF, PHP and SQL.
I am a curious problem solver who enjoys turning complex challenges into structured, maintainable
solutions. Previous engagements include SAAB, Scania, and TT-Teknik
(web/MMS).
*Currently studying .NET cloud-oriented development at Jensen YH
02 - PORTFOLIO
Selected Personal Projects
My personal projects span both real-world applications and self-initiated technical explorations. Some systems are built to solve practical operational needs and are actively used, while others are developed to deepen my understanding of specific technologies, architectural patterns, or design approaches.
Across all projects, I focus on structured data modeling, clean separation of concerns, and maintainable code. Whether building a production-ready tool or experimenting with a new concept, the goal is the same: to design complete, well-thought-out solutions.
Comet Gym
A production-ready membership management system developed for a gym and currently in active use. The system manages member profiles, membership categories, and operational administration. It includes dynamic generation of virtual membership cards with barcode functionality for scanning and validation.
Developed as a WPF desktop application with structured architecture and local persistent SQL data storage.
Handball Coach
A WPF-based training planning application with a structured exercise library categorized by age group. Coaches can create custom exercises and build training sessions by adding exercises with assigned duration, date, and time.
The system calculates total session length automatically and stores all data locally in a SQL database. Training sessions can generate an HTML overview for digital access both locally and online. The project is currently under active development.
Game Analyzer
A WPF desktop application for structured handball match analysis, backed by a local SQL database. All match events — including lineups, technical errors, and shots on goal — are logged manually in real time or post-match, ensuring precise and customizable data capture.
The system enables detailed statistical breakdowns per team and player and can generate PDF match reports on demand. Its strength lies in transforming manually collected match data into structured insights for performance evaluation and analysis.
Bank API
School project. A backend-focused ASP.NET Web API simulating fundamental banking functionality. The project includes account management, transaction handling, and balance validation logic. Designed with clear separation between controllers, services, and data access layers to demonstrate structured API architecture.
03 - TECHNOLOGIES
Technical Stack
I work across the full development spectrum — from backend logic and database design to frontend interfaces and tooling.
My strength lies in understanding how different technologies connect, and using the right tools to build clean, maintainable and complete solutions.

04 - WORK EXPERIENCE
Selected Experience
Through hands-on roles in software development, I have contributed to building, maintaining, and improving technical systems.
My experience reflects a practical understanding of how development, structure, and delivery come together in real-world projects.
TT-Teknik
non-profitable
Provide occasional maintenance and incremental feature development for a legacy
Maintenance Management System used for managing digital reports online. The work includes
implementing smaller features and troubleshooting within an existing PHP and MariaDb codebase
that was not originally designed for scalable expansion.
Ericsson
HiQ, Consultant
Worked on programming base stations for 5G in C and C++. The assignment involved modifying
existing code as well as developing new code for the mobile 5G network.
SAAB Aeronautics
Assistera, Consultant
Worked with object code review in Ada, C, and C++. The assignment involved producing
representative code for each language and analyzing the resulting object code.
Developed and documented the process for analyzing production code.
Scania
Sylog, Consultant
Worked on programming functions for powertrain control, focusing on torque and speed
regulation for the EMS and TMS motor control systems in Scania trucks.
Programming of the truck control systems, including testing and logging during operation.
The assignment involved mostly independent work, but also some teamwork.
