Behind Codeberg Solutions
You work directly with me.
Codeberg Solutions isn't a traditional agency. The person you discuss your project with is also the person designing and building it.
From the first conversation to launch, you work directly with me - no salespeople, account managers or developer handoffs.
Who I work with
A good fit if you're...
You don't need a technical specification or even know exactly what you need. I work with businesses and founders at different stages - from early ideas to existing products that need to grow.
01/
Launching something new
You have an idea for an app, platform or digital product and need someone who can help turn it into something real.
From early planning to launch.
02/
Improving an existing product
You already have software but need new features, connections to other tools, improvements or an experienced developer to help move it forward.
Build on what you already have.
03/
Replacing a manual process
Your business relies on spreadsheets, repetitive admin or disconnected tools and you want software built around how your business actually works.
Turn manual work into a proper system.
Not sure where your project fits?
Plan your project ->Plan your project
Have an idea? Let's make it a little more concrete.
You don't need a technical specification to get started. Tell me what you're looking to build and the functionality you have in mind, and I'll give you a rough idea of what the project could involve.
Takes about 2 minutes. No email required.

Development cost

Timeline
See roughly how long a project of this scope would typically take to develop.
Additional costs
See third-party services, subscriptions and other costs that may sit outside the development estimate.
Not sure where to start?
Web app or mobile app?
Not every product needs a mobile app. Sometimes a responsive web application is the better choice, while other products benefit significantly from being installed directly on the user's phone.
Answer five quick questions about how people will use your product and I'll tell you which approach I'd usually recommend.
Use this when you have an idea, but you are not sure which platform should come first. The recommendation flows straight into the Project Planner.
What happens next?
You don't need to have everything figured out.
Tell me what you're trying to build or improve. You don't need a technical specification - part of my job is helping you figure out the right approach.
Tell me about your project
Send me a short message or book a call. A rough idea of what you're trying to achieve is enough to get started.
We'll figure out the approach
We'll talk about your goals, requirements and priorities. I'll help identify what you actually need and the best way to build it.
Get a clearer picture
You'll come away with a better understanding of the scope, likely timeline and cost. If it feels like a good fit, we can decide what happens next.
No technical specification required. No commitment to move forward.
