Two ways to hire me
Early stage / Founding engineer
An engineer who owns the product, not just the ticket. I speak business and product as fluently as code, so v1 ships fast without mortgaging v2.
A technical foundation instead of instant tech debt.
Time to market treated as a requirement, with scope cut down to what actually proves the idea.
Startups taught me speed, banks and pharma taught me what survives an audit. I take both.
The whole surface: UX design, frontend architecture, enough Node and CI/CD to ship end to end.
No specs, no tech lead, no design system: exactly the kind of challenge I enjoy and I am great at.
2D / 3D visualization expert
Your chart stopped rendering somewhere past the hundred-thousandth point, or the roadmap says 3D and nobody on the team has time to learn it. That is the work I take.
Canvas 2D/3D, WebGL, WebGPU and Three.js, grounded in strong UX/UI expertise.
Data visualization for large and real-time datasets: custom charts and visualizations.
Performance benchmarking and profiling: frame budgets, memory, paint and Core Web Vitals.
Extreme UI optimization through targeted, creative and advanced performance techniques.
White-label
Your brand, my rendering. Your client relationship stays yours.
Fixed price / Time & material
Fixed price per deliverable, agreed upfront — or plain hourly when your project needs the flexibility.
Your stack
Delivered as Angular, React or vanilla component. Everything is written in TypeScript and ships tested.
Paweł Szymański — 20+ years of frontend engineering for banks and pharma (Goldman Sachs, Roche, Avaloq, BMO), now channelling that same rigour into high-performance rendering.
