What I'm looking for

I'm looking to build scalable SaaS, fintech, AI, or payment products where I can own the full lifecycle—from architecture and database design to deployment—and solve meaningful integration and performance challenges.

At Developers Studio, I've built 10+ production SaaS products across fintech, payments, blockchain, and B2B, owning architecture through deployment. My work includes an Open Banking API layer connecting 1,800+ European banks and merchant reporting software processing €21.3M monthly.

I've built ERP, crypto wallet, payment gateway, AI IELTS, and multi-tenant CRM platforms using React, Next.js, Node.js, Laravel, and PostgreSQL. I enjoy shipping complete products, improving performance, and solving complex payment, integration, and scaling challenges.
