What I'm looking for

I seek a senior backend/platform role at a growth-focused company where I can design scalable systems, optimize costs, and lead engineering best practices.

I am a senior software engineer with over seven years of experience building high-load enterprise systems and real-time data solutions across HR tech, ERP, and payment infrastructure.

I have led large-scale projects, including a scalable HR management platform for 85,000+ employee records and payment integrations across 15 markets, while significantly reducing infrastructure costs and downtime.

My technical strengths span Java, Node.js, Scala, cloud platforms, and data systems; I deliver production-ready APIs, monitoring, and automation that improve reliability and operational efficiency.

I focus on measurable impact—cutting costs, accelerating deployments, and enabling data-driven decisions—while producing clear documentation and resilient architectures that scale for enterprise clients.
