What I'm looking for

I’m seeking remote .NET or full stack roles in FinTech or SaaS, where I can build production systems end-to-end—integrations, ISO 20022 modules, real-time workflows, and reliable releases—while working asynchronously across time zones.

I’m a Full Stack Engineer focused on production-grade FinTech and SaaS delivery, with 4 years building systems that connect banking integrations and payment workflows. I’ve architected and implemented EBICS banking integrations and ISO 20022 CAMT/PAIN payment modules, plus real-time treasury platforms that support cross-border operations for Indian and Swiss clients.

I work end-to-end—from architecture setup to Docker-based production deployments—and I bring a reliability mindset through CQRS/MediatR patterns, clean modular structure, and strong automated testing (xUnit/Vitest). From replacing slow reporting queries with optimized SQL Server stored procedures to delivering sub-second user alerts via SignalR, I aim to eliminate manual reconciliation and improve processing reliability, while collaborating effectively across international time zones.
