About this gig

Full stack developer with hands-on production experience building internal platforms - including systems handling financial and operational data - using Next.js, TypeScript, Node.js and Supabase. I also have an Accounting background, which helps me understand business and financial logic when building dashboards, internal tools and data-heavy applications.


What I can build for you:

  • Full stack web applications (Next.js + Supabase/PostgreSQL)
  • - Internal dashboards and admin panels
  • - REST API integrations (CRMs, ERPs, HubSpot, Monday.com-style tools)
  • - PDF generation and automated reports
  • - Bug fixes and feature additions to existing Next.js/Node projects

I focus on clean, maintainable code and clear communication throughout the project. Let's talk about what you need before you order, so I can scope it accurately.

Full-Stack Developer and Product Owner with a background in Accounting — a rare combination for turning financial and business logic directly into working software. I build with TypeScript, Next.js, Node.js, and PostgreSQL, focusing on financial automation and data platforms that eliminate manual work and operational bottlenecks. I have owned a production platform end-to-end, from requirements to deployment, working closely with stakeholders to translate business rules into reliable, well-tested code. If you need a developer who understands the numbers behind the feature, lets talk.
