About
I’m a Full Stack Product Engineer with 4+ years building and shipping scalable web applications and backend systems in production, including healthcare and enterprise-level systems used in critical environments. I’m comfortable owning features end-to-end, from ambiguous, loosely-specified goals through design, implementation, and delivery.
On the frontend, I deliver responsive user interfaces with React.js and TypeScript, and I focus on UX, priorities, and turning product intent into shipped software. On the backend, I design and build APIs and services with Kotlin, Java, and Spring Boot, applying object-oriented programming and making architecture decisions that improve maintainability.
I’ve designed REST and GraphQL APIs, working with relational databases such as PostgreSQL and Oracle while writing and reviewing SQL queries. I work across the development lifecycle with Git-based workflows and Linux environments, and I collaborate closely with multidisciplinary teams of developers, designers, and product stakeholders.
Beyond software engineering, I bring a cybersecurity background that strengthens secure, resilient software. I’ve performed adversary emulation, penetration testing, vulnerability assessments, and supported system hardening using offensive security practices with Linux and Kali Linux—usually in fully remote settings.
