What I'm looking for

I seek backend roles where I can build scalable, test-driven systems, work with cross-functional teams, and lead technical delivery in logistics or ecommerce.

I am a Backend Engineer with three years' experience designing and delivering scalable solutions for ecommerce, logistics, and real-time tracking systems. I build RESTful APIs, implement NLP features, and drive high test coverage to improve reliability and reduce defects.

I've led teams and projects across startups and education platforms, architecting automated delivery assignment, real-time tracking, and customizable notification systems while integrating multiple delivery partners. I prioritize TDD, maintainable code, and quickly adapting to new domains to generate measurable value.
