About me

I'm a fullstack engineer based in Poland. Over the past four years I've taken products from an empty repo to production — across DeFi protocols, e-commerce platforms, and developer tooling. I own the full picture: schema design, API layer, and the interface users actually touch. I care about UX enough to push back on a spec, and I care about shipping enough to know which battles to pick.

What I bring

Attention to Detail

I notice what others skip — in specs, in data models, in interfaces. Silent assumptions that become data bugs. Missing states that become support tickets. The gap between functional and correct is where I pay the most attention.

Fullstack Delivery

I take features from an empty schema to a working, deployed product without handing off. No gaps between layers, no translation overhead — just someone who owns the whole thing and ships it.

Developer Experience

I build systems other developers enjoy working in — clear conventions, solid tooling including context-aware AI agents and documentation that saves hours of confusion.

Performance

Profiling, measuring, and shipping — never guessing. Fast for every user on every device, without trading off the polish.

Projects

  • Mezo

    Mezo

    React
    TypeScript
    Vite
    TanStack Query
    Chakra UI
    Wagmi
    GraphQL
    Cloudflare Workers

    Bitcoin-backed DeFi protocol. Joined before any web frontend existed and built it from scratch — wallet connection, economic dashboard, vault management, and governance voting. Consumed on-chain data via the protocol's APIs, integrated a third-party swap, and owned Cloudflare edge deployment.

  • eObuwie

    eObuwie

    Vue
    TypeScript
    Tailwind CSS
    Magento
    MySQL

    Large European footwear e-commerce platform. Shipped product page features and UI polish. Reimplemented the user dashboard UI. Owned a B2B data integrity issue where users could bypass the VAT number field — traced it end to end, patched validation, and backfilled incomplete records.

  • Boar Finance

    Boar Finance

    Next.js
    TypeScript
    Chakra UI
    TanStack Query
    GraphQL
    Turborepo
    Wagmi

    Non-custodial crypto wealth management with automated Bitcoin vote delegation. Designed and built the product end to end — wallet connection, GraphQL on-chain data indexing, real-time earnings calculations, and vault interaction flows.

  • Personal Portfolio

    Personal Portfolio

    Next.js
    TypeScript
    React Three Fiber
    Tailwind CSS
    Motion
    Cloudflare Workers

    Built to be as technically interesting as the work it presents. 3D hero scene with custom GLSL shaders, scroll-synchronized Three.js and DOM animations, per-character variable-font spring physics, and a full MDX blog pipeline — all on Cloudflare Workers.

  • Lumo

    Lumo

    Next.js
    TypeScript
    oRPC
    Drizzle ORM
    PostgreSQL
    Cloudflare Workers
    Turborepo
    Puppeteer

    Fullstack automotive marketplace — Drizzle schema, oRPC endpoints, search UI, and a shared component library in one Turborepo monorepo. Next.js on Cloudflare Workers, Neon PostgreSQL, and a custom scraper to populate the vehicle catalog.

  • Boar Network

    Boar Network

    Next.js
    TypeScript
    Tailwind CSS

    Marketing site for enterprise blockchain infrastructure — multi-region RPC endpoints and validator services. Delivered end to end: layout, copy, motion, and deployment. A landing page is often a company's first technical impression; this one communicates reliability before a word is read.

Learn, validate, repeat

Writing is how I validate what I think I know — and find out what I don't. I cover software engineering, web development, and the ideas shaping how I work.

Get in touch

Open to new roles, interesting side projects, and conversations worth having. If you're building something ambitious — or need someone who'll care as much about the interface as the architecture — I'd like to hear about it.
