Project, monthly support or consultant in your team

Project, then ongoing support

What I do

  • Webshops from scratch

    B2B and B2C commerce, from the first architecture sketch to launch and years of running it in production.

  • Fast websites

    Company websites, landing pages and small e-shops with a simple editor, so you can change content yourself. Built with Next.js, React or Blazor, whichever fits your project.

  • Integrations

    PIM, ERP, CRM and payments. I get systems that were never designed to work together to exchange data reliably, with retries, logging and monitoring built in.

  • AI that does real work

    Product data enrichment, image generation, image search and automated approvals. Built into your existing processes, with a person in the loop where it matters.

  • Upgrades and rescue

    Migrations from older .NET (Web Forms, WCF, WPF) to modern .NET and the latest Optimizely, performance fixes, and taking over platforms that need a steady hand.

  • Cloud, hosting and support

    Deployment and hosting on Azure, AWS or Vercel, then ongoing care: monitoring, updates, fixes and new features.

Case studies

Nordic distributor · Optimizely · AI

AI approval of supplier campaigns

Challenge
Suppliers submit marketing campaigns, and the team reviewed every one by hand.
What I built
A two-step AI review. The first AI checks each campaign against rules and policies the client defines, and explains its reasoning. A second AI acts as a judge: it checks both the campaign and the first AI's verdict. Clear cases are approved automatically, borderline ones go to a person with the AI's notes attached. Batch runs over hundreds to thousands of submissions show how the AI decides before anything goes live, so the results stay predictable and stable.
Result
Around 80% of campaigns are approved automatically. The team spends its time only on the borderline cases, and a review takes minutes instead of days.
Norwegian hardware retailer · DynamicWeb

AI that fills in the product catalogue

Challenge
Thousands of products arrive with missing attributes and without good images, and filling them in by hand takes a lot of the team's time.
What I built
Three AI tools built into the DynamicWeb PIM. Select hundreds or thousands of products, and the AI proposes the missing attribute values from the product data, generates product images from those attributes, or finds real product photos on websites the client approves. Every value is checked against the allowed options, and nothing is saved until someone approves it, one by one or in bulk. The team reviews and approves instead of typing.
Result
Thousands of products enriched in hours instead of months, and the team spends the saved time on other work.
Nordic distributor · Optimizely CMS & Commerce

Multi-site, multi-market B2B and B2C commerce, from scratch

Challenge
One new platform had to run several sites and markets, B2B and B2C, connected to PIM, ERP and payment providers.
What I built
As architect: a new platform on Optimizely CMS and Commerce that runs four B2B and B2C sites in Norway and Sweden, with integrations to PIM, ERP and Nordic payment providers.
Result
Four B2B and B2C sites in two countries on one shared platform: one codebase, one set of integrations, and new markets launched without starting over.

About

I'm Václav. I have built software since 2004 and commerce platforms since 2018. Along the way I have had almost every role on a project: tester, developer, architect, consultant, team leader and team manager. I have also led teams in the Czech Republic, India and China, always in direct contact with customers.

Today I am the architect who also writes the code: I talk with your business people, design the solution, build it, and stay to run it. I am also an AI enthusiast: I use AI every day for coding, code review, debugging and documentation. That means faster delivery, and every change is still reviewed by me. What works well, I bring into client projects.

I work remotely from Ostrava in the Czech Republic, for clients across Europe, from small businesses to international manufacturers.

How I work
  • You work directly with a senior architect. No juniors, no account managers.
  • I work with several platforms, so I recommend the one that fits you.
  • I have been in almost every role on a project, so I understand what the testers, developers and managers on your side need.
  • I own the result from the first sketch to production.
  • I explain technical choices in plain language, so you can make the call.
  • I build for production: logging, monitoring and a plan for when something breaks at 3 a.m.
  • I bring ideas for doing things smarter, including AI where it pays off.

Experience

Developer since 2004, team leader since 2015 and software architect since 2018. Since 2022 I have worked independently as an architect and consultant.
