Your system should drive your business. Not hold it back.
I'll turn software from a brake on your business into its engine. Without building your own development team.
The symptoms that bring companies to me most often.
Companies come to me when they've hit a ceiling. Their application is slowing the business instead of driving it.
Off-the-shelf solution hit its limit
You're paying for features you don't need. And the one you do need simply isn't there. Every Black Friday is a lottery.
Technical debt is holding you back
Adding a new feature takes months. A change in one area breaks three others. The original developer is unreachable or doesn't know why it was built that way.
Data and systems don't talk to each other
Employees manually copy data from Excel into ERP. Warehouses, orders, accounting: every system lives its own life.
Vibe coding: A powerful tool in the right hands. A ticking bomb in the wrong ones.
Every developer today says: I use AI. Martin says something different: I know when generated code fails on security, and I have real examples. He uses AI tools daily. The result is faster delivery without quality compromises.
But every week he fixes problems from "vibe-coded" add-ons where AI generated functional code, with gaping security holes.
Recent case: a client came with an AI-programmed e-shop extension. It looked functional. But an attacker could change the price of any product in the cart. Just by modifying one parameter in the request.
Speed with AI is an advantage. Speed without knowing when the code fails is a deferred disaster.
How I can help
From database schema design to custom application development to AI integration or team mentoring. No vague promises, concrete deliverables.
Discovery Workshop
Before you invest hundreds of thousands, we'll spend 2 intensive days defining the architectural roadmap, eliminating dead ends, and creating an exact investment estimate. The output is 100% yours: build it with me or anyone else.
Custom Web Application
Client portals, internal systems, process automation, API integrations. No vendor lock-in: all source code and intellectual property rights transfer to you upon payment. Deployed on an open-source stack with full documentation.
E-commerce Systems
Custom e-commerce, B2B portals, migrations from off-the-shelf platforms. Deep integration with ERP, warehouse, carriers, payment gateways. Architecture proven in live operation of hundreds of e-shops.
Custom AI & Mentoring
LLM integration into your applications and processes, deploying and fine-tuning local models (Ollama, LM Studio, custom fine-tuning), RAG pipeline design. Also technical mentoring for developers and IT managers who need to understand architectural decisions and pick the right tool for the right problem.
What collaboration looks like
No black box. A structured process with clear milestones.
First contact
Contact me. You'll get a quick response and a few clarifying questions. Based on your information, I'll determine if and how I can help.
Scope and engagement model
We'll discuss exactly what I'll deliver and how to structure the billing: one-time investment or monthly retainer. You'll know exactly what you're getting and what the next steps are.
Development and iteration
Phased development with regular communication. We refine the result based on your feedback: no surprises at the end.
Support and future development
After launch I'm available for further changes and support.
Martin Březovský
Senior Developer & Technology Consultant
For over twenty-five years I've been designing and building systems that must work: under pressure, in production, without excuses. I started when "e-commerce" was still an experiment. Today, the platform I built powers approximately 1% of the Czech e-commerce market.
But numbers aren't what drives me. It's the moment when a client comes with a system that's holding them back, and we rebuild it together so it drives them forward instead.
My philosophy
The most important thing I can do for you is sometimes say no.
I don't want to do work that doesn't make long-term sense: not for the client, not for the project. I refuse to promise fast and cheap when the result will be a system that needs years of patching just to keep working. First I understand your problem, then I propose a solution.
What I work with
Frequently Asked Questions
Things every client should think through before the first call.
What is real technical debt and why does it kill margins?
Technical debt isn't just old code. It's every decision that saves time today and costs you tomorrow: missing tests, undocumented logic, patches instead of proper solutions. The problem is it grows exponentially. Companies notice it when adding a new feature takes months instead of days, or when every change breaks something else.
When does a custom system make sense vs. an off-the-shelf solution?
A custom system makes sense when your process is a source of competitive advantage and no off-the-shelf solution can faithfully replicate it. Or when SaaS tools take more than they give. But if you're solving a standard problem, a standard tool will be cheaper and more reliable. My work starts by helping you answer this question correctly before you even reach out to a developer.
Why are cheap vendors the most expensive choice?
Because the price of a project doesn't end with the invoice. A cheap developer delivers in three months what an experienced one delivers in three weeks — but your team pays the technical debt for the next five years. Calculate total cost of ownership: IT team time on fixes, downtime at critical moments, rewriting systems from scratch. I've taken over projects where the fix cost more than the original development.
How to tell if the problem isn't in development but in process chaos?
If the software works correctly but results are still missing, look elsewhere. Common signs: employees are bypassing the system with workarounds, data is inconsistent, every department has their own version of truth. Technology just mirrors processes. Implementing a CRM in a company without defined sales processes is like building a road before knowing where you're going. That's why every engagement starts with process analysis, not the tech stack.
Why does a senior developer need to be able to say "this doesn't make sense"?
Because you're paying for results, not lines of code written. A junior developer builds what's in the brief. A senior asks why — and sometimes discovers the problem isn't technical, or that the proposed solution will create three new problems. The most valuable thing I can offer isn't fast code, but a technology strategy that aligns with your business.
Let's start a collaboration
I usually respond within two business days. Every inquiry gets a personal reply.
I work with a number of specialists. If your project goes beyond my specialization, I'll recommend an expert I personally vouch for, or handle it myself within project management so you don't have to worry about a thing.
