What I'm looking for

I seek backend-focused roles where I can design scalable APIs, automate workflows, lead delivery, and improve product reliability in an iterative, cross-functional team.

I am a Full Stack developer with a strong backend focus who builds APIs, automations, and scalable services that solve real business problems without hand-holding. I prioritize rapid testing, iteration, and pragmatic engineering to deliver production systems that generate revenue.

Across roles from backend engineer to lead backend developer, I have redesigned architectures for scalability, optimized database performance, and deployed services on AWS and serverless platforms. I have led small distributed teams and shipped iterative product updates while integrating AI-driven components and third-party services.

I excel at automating workflows (Celery, N8N), integrating REST/SOAP systems, and handling PostgreSQL and MongoDB at scale, and I seek opportunities where I can drive backend reliability, automation, and product delivery.
