What I'm looking for

I seek a role building scalable backend and cross-platform mobile products, with strong CI/CD, cloud-native practices, mentorship opportunities, and measurable impact on performance and cost.

I am a Senior Full Stack & Mobile Engineer with 7 years of experience building scalable backend architectures, microservices, and cross-platform mobile applications. I specialize in Java (Spring Boot), Python (FastAPI/Django), Node.js, and JavaScript/TypeScript, and I have delivered production mobile apps using React Native and Flutter serving 25k+ users.

I've architected AI-driven automation and fintech platforms that reduced operational costs by $30k/month, built systems processing 50k+ daily transactions with sub-150ms latency, and launched developer productivity and enterprise applications with high uptime. I prioritize robust cloud-native architectures on AWS, rigorous testing and CI/CD, and mentoring teams to improve velocity and code quality.
