Full-stack developer (Next and Node)

Duration: MVP, ~ 2 months and further support (potentially)
English: B2 or higher

What needs to be done:
The goal is to "convert" an existing Power BI dashboard into a B2B SaaS application.

Currently, the dashboard consists of:
- 3 main areas: Company analysis, competitive analysis, solution marketplace
- 8 tabs. which need to be redesigned
- Charts are including tables, lists, tree maps, KPIs, radial gauge, trends, heatmaps, multidimensional diagrams, geodata visualization, comparison views
- Dashboard data comes from a data lake with data about 4M companies (~1TB)
- Prototype C# API and Azure SQL DB is existing (needs rework)
- Custom dashboard creation: selected tech stack must enable this in future
 

Tech stack (must have):
- Next
- Node (Nest or Express)
- TypeScript
- SQL databases

Nice to have:
- AWS или Azure Microsoft
- Cursor AI

Working flow:
- Agile development in 1-week releasable sprints with review
- Rapid development by using existing frameworks/templates like supastarter Next.js SaaS starter kit together with Cursor / Windsurf
- Communication via Teams or Slack
- Code sharing via GitHub
