Senior Software Engineer building and owning production SaaS, AI, payments, and backend systems from architecture to deployment.
What I'm looking for
I’m a Senior Software Engineer with experience building and owning production SaaS products, AI systems, payment platforms, and complex integrations.
At AutoSetter, I’ve owned major parts of a production AI SaaS platform that automates customer conversations, lead qualification, follow-ups, booking, and pipeline workflows. I’ve worked across the architecture, PostgreSQL data layer, event-driven processing, AI orchestration, background workers, reliability, and production operations.
At Sagan Recruitment, I was the primary engineer on CayPal, a multi-tenant payment operations platform. I worked across payment and authorization workflows, PostgreSQL, QuickBooks integration, EDI banking pipelines, security, and production releases.
Earlier at Inostrík, I built multi-tenant SaaS infrastructure with strict tenant isolation and RBAC, including systems supporting 1,000+ concurrent users.
I’m strongest when I can take ownership of a problem end to end, from understanding the requirement and designing the system to building, deploying, debugging, and maintaining it in production.
I’m interested in remote Senior Software Engineer, Lead Engineer, and Full-Stack Engineer roles, particularly with SaaS, AI, automation, fintech, and technically complex products.
