Senior Backend Engineer | Node.js | Python | APIs & Cloud

I am a senior backend engineer with strong experience building scalable APIs, backend services, database architectures, and integrations for modern web applications.

I specialize in designing reliable backend systems using Node.js, Python, Django, PostgreSQL, MongoDB, and cloud technologies. My focus is building clean architecture, secure authentication systems, efficient data workflows, and well-structured APIs that support high-quality frontend experiences.

I have experience developing RESTful APIs, third-party integrations, database optimization, business logic implementation, and backend infrastructure for SaaS platforms, CRM systems, and AI-powered applications.

I help teams build maintainable backend foundations with clear API contracts, strong security practices, and scalable systems that can grow with the product.
