Independent developer building SpendPilot, a cloud cost-optimization SaaS, while pursuing data engineering roles.
HungaryWhat I'm looking for
As an Independent Developer, I build and ship web products end to end, including SpendPilot, StackPilot, and client sites. SpendPilot is a live cloud cost-optimization SaaS with a Next.js frontend and a Python/Flask backend on Azure PostgreSQL.
At EPAM Academy, I focused on PostgreSQL and warehouse design, building a DWH project using the Inmon approach with a 3NF core and data marts. I also automated ETL/ELT pipelines and built reporting in Power BI.
My projects have also included StackPilot, a personal AI assistant in Hungarian and English, and Demo Safe, a bilingual business website. I’m currently seeking a data engineer role.
