How I can help

The engagements companies hire me for most often. From a one-off audit to a long-term technical partnership.

Technical audit & architecture review

An independent look at your architecture — risks, technical debt, and a concrete improvement plan. Fixed scope, fixed price, delivered in 1–2 weeks. The ideal first step.

Fractional CTO

A long-term partnership: ownership of tech strategy, architecture design, and development leadership. Senior technical leadership without the cost of an in-house CTO.

New product — from design to production

I turn a business idea into working software. Architecture, development, deployment, and operations — one person responsible for the whole outcome.

Legacy modernization & technical rescue

A system that outgrew its original design, or a project that went off track. I analyze, stabilize, and rebuild step by step — without stopping your business.

AI automation

AI agents that automate real business processes — built securely from day one. My production agents handle thousands of calls monthly.

Own Projects

BlockHost.cz

Managed hosting for businesses that outgrew shared hosting

Dozens of businesses running for years with zero downtime

Problem

Czech mid-sized businesses are stuck between cheap shared hosting (unreliable, no support) and expensive enterprise cloud (overkill, complex). They need something in between — reliable, personal, local.

Approach

Built a managed hosting platform from scratch — dedicated servers, WordPress hosting, automated backups, monitoring. Personal onboarding and custom solutions per client. SSD performance with geographic backup redundancy.

Outcome

Dozens of businesses on a platform running for years with zero downtime. Clients moved from unreliable shared hosting to enterprise-grade — and still have a direct line to me.

Zvednu.cz

AI phone assistant that never sleeps

Thousands of calls handled by AI every month

Problem

Small businesses — lawyers, dentists, craftsmen — miss calls because they have no receptionist. Missed call = lost customer. Existing solutions are expensive or require complex setup.

Approach

Built an AI phone answering service — picks up calls 24/7, customizable greeting per business. AI converts speech to text, classifies caller intent via LLM, and sends structured summaries via push notification or email. Setup takes 3 minutes.

Outcome

Running service handling thousands of calls monthly. Businesses that used to miss half their calls now never miss a single one. Proof that AI communication automation works in production, not just in demos.

CoolLetenky.cz

Cheap flight tracker from 10+ portals in one place

98% AI data extraction accuracy

Problem

Dozens of flight deal portals exist, each publishing offers in a completely different format and structure. Czech travelers have to check them one by one. No aggregator combined them with filtering for Czech departures and local pricing.

Approach

Built a flight deal aggregator that scrapes 10+ discount portals, monitors prices, and sends notifications. AI replaced thousands of lines of parsing code — every portal has a different structure, but a single AI model extracts offer details (origin, destination, price, date, carrier) at 98% accuracy, with zero source-specific code. Regional filtering for Prague, Brno, Bratislava departures. Full Android app.

Outcome

Thousands of users tracking flights via web and Android app. Adding a new source takes hours instead of days — AI handles any format without new code. Proof that LLMs replace brittle rule-based code in production.

GS

GasStorage CZ — NomSys

Nomination system for the largest gas storage operator in Czechia

2.7 bcm storage capacity managed by the system

Problem

Czech Republic's largest underground gas storage operator (2.7 bcm capacity) needed a digital nomination workflow aligned with gas market principles.

Approach

Designed the nomination process workflow and built integrations with NET4GAS (gas transmission operator) and OTE (electricity and gas market operator).

Outcome

Running nomination system handling 2.7 bcm gas storage capacity, integrated with key Czech gas market operators.

W

Welcomo

Self-service visitor management for buildings

Problem

Buildings need a modern alternative to traditional reception for visitor check-in — scalable, automated, and secure.

Approach

Helped build a terminal kiosk system — QR codes, video verification, access card issuance. The system fully replaces traditional reception desks.

Outcome

Production system that eliminated the need for a full-time receptionist. Visitors check themselves in — from arrival to access card.

WC

WhiteCat Tech Lead

IoT platform — firmware, backend, mobile app

Problem

Product required custom firmware, backend API, and mobile app — three teams that needed coordination under a unified architecture.

Approach

As Tech Lead, drove architecture decisions and coordinated the team. Personally developed the Go module running on the OpenWRT router.

Outcome

Three independent teams (firmware, backend, mobile app) delivered the product as one — thanks to unified architecture and central coordination.

TŘ

Thajský Ráj

Complete digital transformation of a massage chain

10+ years of ongoing partnership

Problem

Thai massage chain with 5 locations in Prague needed digital presence, booking system, and operational tools — from scratch.

Approach

Led complete digital transformation — e-commerce, reservation system, API integrations, hosting and operations. Direct client communication, requirements gathering, translating business needs into technical solutions.

Outcome

10+ years of ongoing partnership. Complete digital operations stack from e-shop to internal tools.

FA

FAMU — Studio Dispečink

Equipment booking system for one of the oldest film schools in the world

Problem

FAMU film school manages hundreds of pieces of professional equipment — cameras, lighting, sound, editing suites, studios. Manual tracking led to double bookings, poor visibility, and administrative burden on reception staff.

Approach

Built a web-based booking system — equipment and facility management, confirmation workflows, automated loan rule enforcement, and time-slot scheduling for studios.

Outcome

Running internal system at dispecink.studiofamu.cz eliminating double bookings and streamlining student access to equipment.

MB

MarketingBright

Internal marketing tools for a Dutch SaaS platform

Problem

Dutch marketing platform needed web-based strategic analysis tools — SWOT, BCG matrix, Business Model Canvas and more — as part of their SaaS product.

Approach

Developed a suite of interactive web tools — strategic matrix visualizations, positioning tools, and analytical templates integrated into the existing platform.

Outcome

Toolset used by businesses, consultants, and students across the Netherlands. Expanded the platform’s offering with strategic analyses it previously lacked.

AI automation — done securely

I build AI agents that automate real business processes. Unlike most AI vendors, I architect them with security from day one — access control, audit trails, prompt injection protection. Because I understand the architecture under the AI, not just the API on top.

Autonomous agents, not chatbot wrappers

Agents that independently handle communication, extract data, and drive processes — in production, not in a demo.

Security from day one

Access control, audit trails, and prompt injection protection are part of the design, not an afterthought.

AI where it helps

Where a simpler solution is enough, I recommend the simpler solution. The goal is a working process, not AI at any cost.

What I bring to your project

Systems that grow with your business

I design architecture to last years, not months. From gas nomination systems to an AI phone assistant to a hosting platform — built to fit and built to last.

From first sketch to running system

I build it and I run it. No handoffs between teams, no lost context. One person responsible from first design to running production.

Business first, code second

I don't start with technology — I start with your problem. The result isn't code, it's a working solution that makes money or saves time.

A network of specialists within reach

I'm your primary technical partner. But when a project needs specific skills outside my domain, I bring in trusted specialists I've worked with for 5+ years. You talk to me — I deliver the result.

UX & UI design

User research, wireframes, visual identity, and design systems. I work with designers who understand product development and can design interfaces that actually work.

DevOps & infrastructure

CI/CD pipelines, cloud architecture, monitoring, and scaling. For projects that need dedicated operations, I bring in infrastructure specialists.

Who I work best with

Long-term partnerships

The best results come with time. Most of my partnerships last years, not months.

Technical depth, not band-aids

System architecture, legacy refactoring, new products. Not small tweaks or one-off websites.

Direct collaboration

I work directly with you, no layers. You talk to the person who writes the code — no project managers in between. I need a partner, not a task assigner.

Open capacity for 1–2 new projects

Currently taking on 1–2 new projects. Availability changes with every new engagement — first come, first served.
