What I'm looking for

I seek fintech roles where I can apply my frontend strengths while expanding backend expertise, on collaborative teams building scalable, secure products with strong testing and impact.

I am a full-stack developer with six years of experience building dynamic websites and mobile applications, focused on delivering impactful digital solutions. I bring a strong frontend foundation and am actively expanding my backend capabilities to build robust, scalable systems.

In fintech roles I designed and delivered modules for position management, credit concentration analysis, and automated PDF population, and built a RAG MVP using all-MiniLM-L6-v2 embeddings and a LLaMA-based LLM. I routinely use Django REST and Vue.js alongside modern frontend stacks.

I've contributed to client onboarding and CLM work, maintaining test coverage above 90%, and built ecommerce, payment gateway, and subscription solutions while integrating many third-party APIs and automation tools. I have experience across React, Next.js, React Native, GraphQL, Node.js, and PostgreSQL/MySQL.

I prioritize clean, testable code, strong cross-team collaboration with designers and backend engineers, and measurable impact—reducing manual effort, improving operational efficiency, and enhancing user experience. I am seeking fintech opportunities to deepen backend expertise while contributing to full-stack projects.
