Built forfintech.
I'm a product-focused software engineer specialising in React Native and TypeScript. I led mobile development at Verofy, a UK FCA-authorised payments provider, taking the merchant app from MVP to production. Before that, I consulted for GoPay, a payment-gateway startup, helping large Czech and Slovak companies with their integrations. I build fintech and payments products, the integrations behind them, and the regulatory needs they carry.

01 About
A product engineer
who speaks fintech.
I'm a software engineer focused on product. Over 8+ years I've specialised in React Native and TypeScript, with a backbone in payments and fintech. At Verofy, a UK FCA-authorised acquirer, I led mobile development from MVP to production and headed a small team, owning the React Native app and the surfaces around it. Earlier, at the payment-gateway startup GoPay, I consulted for large Czech and Slovak companies on integrations, API design, and onboarding. I take full ownership of a product surface: the product decisions, the interface, and the production code behind them.

02 Services
What I build
for fintechs.
Onboarding & KYC/AML flows
Onboarding journeys that satisfy compliance and still convert: identity verification, document capture, and e-signature, built into the product.
Payment-gateway integration
Integrating payment gateways and fintech APIs cleanly. It's the consulting I did at GoPay, advising large Czech and Slovak companies on integrations, API design, and onboarding.
Product engineering & consulting
I join your team to own a product surface end to end, or advise on a payments or fintech build, from architecture to shipped code.

04 Why me
Why teams
work with me.
I ship production code
Not mockups or prototypes. Production React Native and TypeScript, in your stack and to your standards.
Onboarding UX that converts
My home turf is the user-facing layer: KYC and onboarding flows that feel effortless and actually get finished, not forms that simply tick a compliance box.
Payments and compliance, first-hand
I've worked inside an FCA-authorised acquirer and a payment gateway, so I know what KYC/AML, PCI, and audit trails ask of a product. When a build needs deeper regulatory sign-off, I bring in trusted specialists.
Full ownership, product thinking
I take a surface from decision to deployment, weigh the trade-offs, and name the risks. I don't just close tickets.
Design partners when you need them
I own the product and front-end engineering. For dedicated UI, brand, or illustration work I bring in vetted designers, so you get the right craft without lining up another vendor.
Insured and dependable
Covered by professional liability insurance for IT services, so an engagement starts on a clear, professional footing.

● FAQ
Questions,
answered up front.
- How do we get started?
- With a short intro call. You tell me what you're building and where you need help; I'll be honest about whether I'm the right fit and how I'd approach it. If it's a match, I scope the work before anything begins.
- How do you charge?
- Time-based (day or sprint rate) for ongoing product work, or a fixed price for a clearly defined scope. Estimates are transparent and I flag risks early, so there are no surprises on the invoice.
- Do you work remotely?
- Yes. I'm based in the Czech Republic and work remotely with teams across Europe and the UK. I led mobile at a UK company that way for years. Your process, your stack, your timezone.
- What do you work on?
- Fintech and payments product engineering: React Native apps, onboarding and KYC/AML flows, payment-gateway integrations, and the web surfaces around them. React Native, TypeScript, Next.js, Node.js.
- Can you join an existing team?
- Yes. Embedded as a peer to own a product surface end to end, or to de-risk a critical flow before a deadline. Senior ownership, low overhead, no long onboarding.
- Is working with you low-risk?
- I ship reviewed production code, keep a clear trail of decisions, and carry professional liability insurance for IT services, so an engagement starts on solid footing.
