About
I'm a frontend engineer with a decade of experience building for the web, currently focused on Vue, Nuxt, and TypeScript. Over the past several years I've specialized in fintech payments — building secure checkout and payment flows across card, wallets, and open banking, with particular attention to PCI scope on the card side: tokenization, 3D Secure, and vaulting integrations that keep raw card data off the company's own systems.
The problems I find most interesting live where user experience and compliance pull in different directions — keeping a flow simple without cutting corners on security and regulation requirements.
Recent Projects
Merchant Payments Platform
Owned the frontend for a payments platform used by merchants across many countries to offer multiple payment methods to their own customers — card payments, Apple Pay, Google Pay, Pix, Boleto, Trustly, and Volt — with per-merchant control over which methods to expose. The core challenge was unifying fundamentally different integration models (redirect-based regional methods, card flows, wallet APIs) behind one consistent, embeddable interface.
White-Label Bitcoin Exchange Platform
Owned the frontend for the end-customer application of a white-label Bitcoin exchange platform — user authentication (email and e-ID), compliance onboarding, and buying, selling, and transferring Bitcoin — sold and customized across up to four brands from one shared codebase. The core challenge was a design system and feature-toggle architecture flexible enough for real per-brand differences, built and maintained under the strict compliance requirements of a regulated financial product.
Card Payments SDK
Designed and built a framework-agnostic TypeScript SDK abstracting card tokenization and 3D Secure behind a single interface, used as the underlying card-payments engine for consumer-facing frontend applications — supporting multiple tokenization and 3DS providers (PCI-Proxy, Evervault, Paysafe) interchangeably. The core challenge was normalizing different provider request/response shapes and 3DS challenge/redirect flows so consumer apps never needed to know which provider was active underneath.
BTC Market Data Proxy
Built an AWS Lambda service powering real-time Bitcoin price charts and exchange rates for a frontend application — proxying third-party market data providers, keeping API keys server-side and avoiding the CORS restrictions direct client calls would have hit. When a licensing change later forced a provider switch, consumers were unaffected — the interface was designed around a stable response format, not either provider's raw API shape, so the swap required no frontend changes.
