What I'm looking for

I am looking for a role that challenges me technically and allows for growth in a collaborative environment.

As a Senior Full Stack Engineer with over 9 years of experience, I have a proven track record of designing and building performant, secure, and maintainable systems across various domains including AI, Healthcare, FinTech, and SaaS. My expertise spans multiple programming languages such as Java, Python, JavaScript, and TypeScript, allowing me to architect and deliver highly complex systems with clean abstractions and first-principle-driven designs.

I thrive in regulated environments, ensuring compliance with standards like HIPAA and PCI-DSS. My recent work includes developing a FastAPI-based ingestion pipeline for healthcare documents and building a multi-acquirer payment gateway. I am equally comfortable crafting intuitive UIs and navigating intricate domain logic, always aiming to create solutions that support real people in their challenging roles.
