What I'm looking for

I’m looking for a role where I can architect secure, high-performance products, collaborate cross-functionally, and own complex features end-to-end. I want a team that values continuous learning, measurable UX improvements, and modern cloud delivery.

I’m a Senior Full Stack Engineer with about 11 years of experience building and maintaining consumer-facing applications. I focus on microservice architecture, API models, and server-side development to deliver robust, scalable systems.

In my current role at Haneke Design, I architect, implement, and maintain critical user-facing components using React, Python, and AWS cloud. I’ve improved scalability by 30%, accelerated delivery timelines by 25%, and reduced data retrieval times by 40% through targeted API and system design.

I also bring a strong security and reliability mindset, implementing security best practices that reduced vulnerabilities by 60% and supported compliance. I led migration of legacy systems to AWS cloud, cutting operational costs by 50% and improving system reliability.

I’m collaborative and proactive—I train junior developers, work closely with designers and researchers, and stay current with emerging technologies. Previously at GE HealthCare and Offers, I improved clinician decision-making speed by 40%, reduced manual intervention by 50%, enhanced data retrieval efficiency by 30%, and implemented CI/CD pipelines that reduced deployment times by 40%.
