What I'm looking for

I seek senior technical roles building scalable full-stack systems, with strong engineering culture, CI/CD, mentoring opportunities, and cloud-native architectures.

I am a Senior Full Stack Developer with 9+ years delivering scalable, high-performance solutions across banking, government, ERP, and e-commerce domains. I focus on backend systems with Node.js (NestJS, Express), modern API design (REST, GraphQL), and responsive front ends with React and Next.js, emphasizing clean architecture, maintainable code, and measurable business impact.

I have led modernization efforts, built event-driven platforms, and improved performance and observability across cloud environments (AWS, Azure, GCP). I mentor engineers, champion testing and CI/CD, and consistently reduce latency, technical debt, and operational errors through performance optimizations and architectural best practices.
