I lead frontend and full-stack work in banking, AI tooling, and product teams. My job is the part between a messy requirement and a system someone else can still maintain.
Before engineering I spent eight years in customer operations, fraud prevention, regulated environments, and IoT incident analysis. I saw what an unclear interface costs the person on the other end of it, and that is still the first thing I ask about a design.
Based in Prague. I take selected freelance projects and I am open to senior engineering roles.
01 / selected work
Each case study covers what I owned and why the key decisions went the way they did.
Led the frontend and BFF side of an online-banking modernization. We moved legacy functionality toward a micro-frontend architecture, and I tightened the API boundaries, the tests, and the accessibility work around it.
Built the full-stack tooling for machine-learning model metadata, plus an AI-assisted workflow that pulls structured fields out of scientific PDFs. Validation and GitHub automation sit around it.
A learning platform for developers that I run as a live product. Structured topic paths, quizzes, progress tracking, and real-time multiplayer on a React and Supabase architecture I have to keep maintainable on my own.
02 / experience
Engineering roles first, in detail. The operations years are here too, because that is where I learned to read risk.
Apr 2026 – Present
Prague, Czech Republic
Web Integrator
Lead frontend work and set the conventions for how the team uses AI tooling. Accessibility and web standards go into the specification the team builds from.
Jul 2025 – Mar 2026
Prague, Czech Republic
EmbedIT
Led the frontend and BFF side of an online-banking modernization, and helped move legacy functionality toward a micro-frontend architecture.
May 2024 – Jun 2025
Barcelona, Spain
Ersilia
Built a full-stack application for structured machine-learning model metadata, and an AI-assisted scientific-PDF workflow, inside an open-science team.
Aug 2023 – Jan 2024
Barcelona, Spain
beKind
Built the frontend of a B2B marketplace connecting charities and corporations, and carried a company rebrand into the production product.
Feb 2023 – Jul 2023
Barcelona, Spain
Take a Break
Built a B2B meditation-booking application across the product UI, the data layer, payments, authentication, and deployment.
These roles came before the first production code anyone paid me to write. Investigating fraud and cold-chain incidents is where I learned to reconstruct what happened from partial data, and to keep a customer informed while the answer is still missing.
Sep 2020 – Jan 2023
Reykjavík, Iceland
Controlant
Investigated critical cold-chain incidents on pharmaceutical shipments using live IoT telemetry.
Dec 2018 – Aug 2020
Gibraltar
Entain Group
Investigated fraud, money-laundering patterns, and user-protection risks in a regulated environment.
Oct 2015 – Nov 2018
Brno, Czech Republic
Kiwi.com
Resolved complex booking failures across airline and CRM systems, for customers and B2B partners.
03 / approach
What I argue for when the architecture or the release date is under pressure.
principle / 01
I want explicit contracts between the frontend, the backend, and any external service. When a boundary stays vague, the complexity behind it ends up in product code, and getting it back out costs far more than defining the contract would have.
principle / 02
Accessibility, tests, performance, and maintainability belong in the ticket, the review, and the release checklist. Anything scheduled for afterwards gets cut the moment the deadline moves.
principle / 03
Before I choose anything technical, I want to know who depends on the system and what happens to them when it breaks. That answer usually constrains the design more than the framework does.
principle / 04
I use AI for research, scaffolding, and the repetitive parts of delivery. Validation, tests, and security boundaries stay explicit, and a person still reads the diff.
04 / additional work
Smaller products, experiments, and client sites, kept short because that is the size they are.
Independent product
My own operating system for freelance and employment work: projects, client opportunities, Czech invoicing with VAT and QR payment, money, planning, and a job-offer feed, with contextual AI and a natural-language quick add built on Claude.
Product owner and developer · Next.js · Supabase · Claude API
Independent experiment
A company operated by a council of four AI agents instead of a management board. Every decision, cost and claim is written to Git and published, and deterministic guardrails hold the whole system to a $20 monthly cap. Built and complete; the venture itself has not been founded, so the site runs on labelled fixture data.
Creator and developer · Next.js · TypeScript · Claude API · GitHub Actions
Independent product
A bilingual daily on AI and technology. A scheduled job scrapes the sources, curates them with Claude, writes one selective feature, and commits the result as a static issue.
Creator and developer · Next.js · Claude API · GitHub Actions
Independent product
A board strategy played on real Czech cities. Room codes, real-time play for two to four players, a trivia round on every bank event, and Czech and English versions. No account needed.
Full-stack developer · Next.js · Payload CMS · Ably
Product experiment
A Czech publication that reconstructs the world someone grew up in. Enter a birth year and a place and it assembles a report from verified period data. It runs entirely in the browser, with no backend, no account and no stored reports.
Frontend developer · React · TypeScript · Vite
Client website · Frontend engineer
A bilingual site for a Czech passenger and freight transport company, covering its services and fleet. I built the page structure and metadata for local search.
Client website · Frontend developer
A site for an exterior-cleaning service, with before-and-after comparisons and a direct route to a quote request.
Client website · Frontend developer
A product and company site for a Czech spa-wafer maker: its history, its range, and how it distributes.
Earlier product work · Fullstack Developer · 2023
A B2B meditation-booking product covering the booking flow, achievements, content, payments, authentication, and real-time updates.
Earlier product work · Frontend Developer · 2023–2024
A B2B marketplace connecting charities and corporations, delivered alongside a company rebrand.

06 / education
Two intensive programmes, and production codebases since.
Feb 2024 – Jul 2024
Barcelona, Spain
Computer Software Engineering
An intensive software-engineering academy in Barcelona: full-stack development, data structures, algorithms, and building working products in a team.

Web Development
A web-development bootcamp, and my first real work in HTML, CSS, JavaScript, and Vue.

07 / contact
Tell me what the system does and where it hurts, and I will tell you whether I am the right person for it.
Email or LinkedIn reaches me fastest. My code and current product work are on GitHub, linked below.
