We specialize in empowering professionals through a comprehensive array of courses and workshops on Software Design. Our offers are flexible, including options for in-company training to suit your organizational needs
Our experienced software architects and managers take leadership roles in customer projects and organisations, ensuring predictable and reliable delivery of commitments
This training teaches how to create an Application Infrastructure that establishes a code structure enforcing Separation of Concerns and adherence to Clean Architecture principles.
Drawing from our extensive project experience, we develop training programs that enhance predictability and reduce the cost of change in software projects. We focus on building the habits that make developers adopt the industry best practices resulting in a flexible code design.
Each course combines discussions on core software design principles and practices with hands-on exercises that demonstrate how to apply them in real-world projects
Our Software Architecture and Project Design services combined, help organisations transition from staff augmentation, where they sell hours, to becoming solution providers, where they deliver project milestones.
We support key architectural decisions, from System Decomposition to Detailed Technical Design.
Our work involves identifying critical system behaviors, core technical requirements, and providing tailored solutions.
We assume the responsibilities and decisions of the architect role, acting as the design lead, technology lead, and process lead.
We apply an effective engineering method to create an actionable project execution plan.
The plan outlines the schedule of activities, allocates resources, and makes strategic trade-offs to meet project goals within constraints, balancing schedule, cost, and risk.
The process provides charts and tools to track progress and adapt the plan during execution.
We help architects, managers, and developers build the skills needed to achieve their goals with ongoing support.
We are available to your team while they work, providing access to our extensive project experience. We engage directly with the project, becoming familiar with its specific requirements and constraints.
Our goal is to build skills within your team, enabling them to achieve their goals independently rather than relying on us.
We lead in design, technology, and process, empowering projects and organizations to achieve their goals. We collaborate closely with client architects, product managers, and project managers, providing coaching and mentorship to help them succeed.
This training teaches how to create an Application Infrastructure that establishes a code structure enforcing Separation of Concerns and adherence to Clean Architecture principles.

Below you’ll find all the resources, slides, and source code mentioned during my talks and workshop.
Feel free to reach out anytime if you’d like to discuss implementation details or need guidance in applying these patterns to your own systems.
Day 1
Designing a Distributed System for Long-Term Development
-> Slides: available soon
Day 2
Implementing Clean Architecture
-> Slides: available soon
Missed the Workshop? Here’s Your Chance
These sessions are meant to inspire and share ideas on how to design for long-term development — and to highlight the importance of investing in an infrastructure that supports your architecture.
The Post-Con Workshop Application Infrastructure in .NET for Clean Architecture dives deeper into the how: it teaches practical ways to build such infrastructure in .NET, passing on proven practices and tools that help you get started fast and accelerate your progress.
If you missed the workshop, you can still catch the online version, available this November — now on sale:

About
Until recently, I was the Solution Architect for a distributed system in the energy sector—a system critical to grid balancing and enabling energy trading. It was a greenfield project that we built from the ground up.Developing and evolving such a complex system over several years, while keeping it in production, required us to uphold a high level of technical quality—especially in the face of team changes. This project allowed me to put into practice the experience I've accumulated for designing distributed systems with long-term development in mind.
In this session, I'll share the story of this project, highlighting design strategies that supported long-term development. Drawing on over 15 years of experience in high-pressure projects that demanded availability, reliability, and precision, I’ll provide practical insights into creating systems that will stand the test of time.

About
Designing Modular Systems poses the critical challenge of determining which services should be deployed together in the same process and which should be deployed separately.Sometimes, you want to maintain a modular development approach, like in microservices, while opting for a monolithic deployment to optimize performance, reduce costs, or simplify infrastructure complexity.
There are also cases where a service needs to be deployed in the same process with others to maximize performance, and at the same time in another process for other clients, to ensure reliability and availability.
This session, demonstrates the design solution to these challenges. It shows real-life project examples of how to achieve the flexibility to decide only at deployment time, without changing the code, which services communicate in the same process and which use inter-process communication.
This webinar is for software architects, senior developers and team leads.
You will leave with a runable example in code that demonstrates how this works and can serve as a reference to implement this approach in your project.

Why Programmers Should Challenge the Stakeholders
Have you ever worked on a state of the art programming project? And then a new requirement arrives, it's implemented and suddenly you're working on a legacy project?
Code Design focuses exclusively on the design phase of software development, striving to restore a strong emphasis on robust software design within the industry. Our goal is to enable our customers to achieve predictability in software development projects.
Over the past decade, Florin has led the design and implementation of complex software systems across industries such as Energy, Finance, Healthcare, Business Productivity Tools, and Insurance. These projects involved distributed systems built for long-term, incremental development, overcoming common challenges to ensure success: on time, within budget, and on quality.
Florin’s experience often includes coaching and training the developers implementing his designs, further enriching the training materials he provides.
At Code Design, Florin collaborates with a team of like-minded professionals and experts, many of whom he has previously worked with, to deliver comprehensive, high-level services in software development.
