Front-end heavy full-stack developer

Náplň práce, právomoci a zodpovednosti:

We are looking for a skilled full-stack developer (front-end heavy) for a globally focused fintech company based in Bratislava that aims to transform the way people understand and manage their finances.

About the project:

Our client is building a platform for intelligent investment decision-making. The solution combines real market data (stocks, ETFs, bonds, commodities, and macroeconomic indicators) with AI agents that generate analyses, predictions, and portfolio recommendations.

The project is currently in the prototype phase, and the client is looking for backend developers to join their team. We are looking for someone who can give this platform a face.

What you will do:

Web Dashboard

• Build an investment dashboard from scratch — portfolio overview, watchlists, charts, alerts
• Connect the frontend to the existing REST API (FastAPI backend)
• Implement authentication (JWT flow — login, registration, protected routes)
• Visualize financial data — price charts (candlestick, line), portfolio breakdown (pie, treemap), performance metrics
• Real-time updates via WebSocket (price quotes, notifications)
• Responsive design — desktop-first but mobile-friendly

React Native App

• Share business logic between web and mobile (shared hooks, API client, types)
• Push notifications for price alerts and portfolio changes
• Simple mobile-first UI — portfolio snapshot, quick actions

Zamestnanecké výhody, benefity:

• Opportunity to be at the very beginning of a new international fintech project (opportunity to work on a real product from scratch — not maintaining legacy code)

• Collaboration with experienced professionals from the global finance and AI sectors

• Modern tech stack without technical debt
• Free access to AI tooling
• Flexible working hours, home office available (office in Bratislava)
• Small team = big impact on the product and architecture

Informácie o výberovom konaní:
We will carefully review every application. Only candidates who meet the requirements and qualifications for the position will be contacted.

What we want to see -
Ideally:

Portfolio / personal website showcasing your work
GitHub with React/Next.js projects
Or simply a link to something you built that looks great.

A link showing what you can do is enough.
