What I'm looking for

I seek technical leadership roles building scalable, AI-enabled backend and cloud systems in collaborative, product-focused teams.

I am a Senior Full Stack Engineer with seven years of experience building enterprise-grade fintech, healthcare, and trading platforms. I focus on delivering reliable, high-throughput systems using Java, Python, and JavaScript/TypeScript ecosystems.

At fintech and telehealth startups I architected AI-driven automation, microservices, and realtime dashboards that processed tens of thousands of transactions and served 10k+ users with 99.9%+ uptime. My work reduced cycle times dramatically and generated measurable cost savings.

I specialize in Spring Boot, FastAPI, React, Node.js, Kafka, and AWS cloud infrastructure, and I orchestrate containerized deployments with Docker and Kubernetes. I also integrate LLMs and AI workflows to automate compliance and support interactions, improving accuracy and reducing manual labor.

I mentor engineers, lead code reviews, and drive improvements in code quality and sprint velocity. I seek to contribute technical leadership, scalable architecture skills, and pragmatic AI integrations that deliver strong business impact.
