MARTIN ERDT / INDEPENDENT DEVELOPER49°46′58″N / 14°41′17″E

Your vision.My code.A new reality.

I turn complex problems into software that makes sense. From the first sketch to an application you can rely on.

Work directly with me. From design to launch.

02 / EXPERTISE

Technology is a tool. The outcome is the goal.

I choose the right solution for your problem. The technology follows the purpose.

M / 01

Web applications & APIs

Business systems, customer portals and services that talk to each other. From the data model to an intuitive interface.

M / 02

Mobile & desktop applications

Useful tools, always within reach. Android applications and Windows software built with .NET, WPF and WinForms.

M / 03

Integration & automation

I connect systems and remove repetitive data entry. Less manual work, more room to run your business.

M / 04

Consulting & ongoing development

I help clarify requirements, understand existing code and plan what comes next. Our collaboration continues after launch.

AI / PART OF MY CRAFT

More intelligence. Still my signature.

I work with AI every day. I use agentic development, build thoughtful workflows and connect tools to help solve real problems.

Agents help with implementation. Architecture, quality and responsibility for the result stay with me.

Let's explore where AI can help
HUMAN × AGENTS
  1. The right context

    Goals, constraints and knowledge of your project.

  2. Agentic development

    Bounded tasks, tools and continuous verification.

  3. Human judgement

    Code review, testing and decisions in context.

  4. Working software

    Software we understand and can keep improving.

03 / THE HUMAN BEHIND THE CODE

Built on experience. Driven by curiosity.

I'm Martin Erdt. I've been developing software under the MedielSoft name since 2011. I enjoy untangling complex problems and turning them into tools people like to use.

You speak directly to the person who designs and writes your software. I understand technology, but first I want to understand you: what you're solving, who it's for and why.

04 / WORKING TOGETHER

A clear direction. From our first conversation.

  1. Understand

    We discuss your goals, users and constraints. We define what the solution needs to change.

  2. Design

    We break the project into clear steps and agree on scope, priorities and how we will work together.

  3. Build

    You see progress along the way. We test behaviour, refine details and prepare for launch.

  4. Evolve

    After launch, I remain your partner for support, maintenance and the next idea.

FEEDBACK FROM A REAL COLLABORATION

What people say after working with me.

Working with Martin was thoroughly professional. Clear and reliable communication is the foundation. When he agrees to something, he delivers. The best solution for our website.
Petr Páral / Studio Art PicturesTranslated from the client's original Czech testimonial.
Martin is a professional in his field. His skills cover even extensive requirements. He sees the wider connections, communicates quickly, thinks logically, explains issues clearly and proposes smart solutions. What is impossible for others is routine for him. That is why he is our number one.
Denisa Říhová / Dancing CrackersTranslated from the client's original Czech testimonial.
We worked with MedielSoft on a new website for our villa. I am very glad I chose Martin. Throughout the project, he and his team were very helpful, bringing new insights, recommendations and advice that we gradually incorporated. If you are looking for a flexible and reliable website developer, MedielSoft is a great choice for an engaging and creative website.
Anastazie Skopalová / Vila SebuzínTranslated from the client's original Czech testimonial.
Working with Martin was a real pleasure. He understood very well how I wanted the website to look and refined every detail. I am very satisfied.
Nikola Kubičková / Salón RájTranslated from the client's original Czech testimonial.
We first met MedielSoft, specifically Martin, in connection with building his house. At first I did not know he was an expert in web applications and programming, and later learned that MedielSoft provides a full range of IT services. Thank you to everyone at MedielSoft, and especially Martin Erdt, for working with us at night and at weekends. I really did not expect that.
Martin Maleňák / Modul-LEGTranslated from the client's original Czech testimonial.
Working with Martin was a pleasure. He understood exactly what I wanted and created a wonderful application.
P. Ř. Translated from the client's original Czech testimonial.
I'm delighted with the result. Achieving 100% satisfaction is difficult, but Martin managed it without the slightest problem.
L. K. Translated from the client's original Czech testimonial.

05 / GOOD QUESTIONS

Before the first line of code.

What kind of software do you build?

I develop web applications and APIs, Android apps and Windows desktop software. My focus is .NET, business systems, integrations and custom tools.

Can we work together remotely?

Yes. I'm based in Benešov, Czechia, and we can work on projects remotely. We agree on communication and delivery at the start.

How much does an application cost?

The cost depends on scope, complexity and how well the requirements are defined. After an initial conversation, I'll suggest an approach and estimate. A price without understanding the project would only be a guess.

Can you help with an existing application?

Yes. I'll first review its condition, code and technical constraints. Then I'll recommend targeted fixes, incremental development or a larger change, depending on what makes sense.

How do you use AI in development?

I use agentic development with clear requirements, project context and continuous verification. AI helps with implementation and automation; architecture, code review, testing and responsibility for the result remain with me.

06 / THE NEXT CHAPTER

Good software starts with a conversation.
