What I'm looking for

I seek senior backend or AI engineering roles where I can lead scalable Node.js/AWS architecture, integrate ML solutions, mentor teams, and deliver measurable business impact. Prefer hybrid or remote opportunities with growth and social-impact focus; open to EU sponsorship.

I am a Senior Backend Developer and AI Solutions Engineer with 4+ years delivering enterprise-grade applications across fintech, healthcare, and logistics. I specialize in Node.js, TypeScript, Python, and AWS, and I design scalable, production-ready systems that serve thousands of users.

I have led cross-functional teams, mentored engineers, and driven architecture decisions that reduced operational costs by 70% and delivered AI pipelines for client solutions. My recent work includes deploying RAG document intelligence, conversational agents, and fraud-detection models in production.

I am pragmatic and outcome-focused: I prioritize reliability, performance, and maintainability while integrating emerging ML tools and DevOps automation. I enjoy mentoring peers, contributing to open source, and building inclusive tech that creates social impact.
