I’m a highly adaptable, results-oriented Full-Stack Developer focused on turning complex ideas into robust, user-centric digital solutions. I enjoy the full lifecycle—from initial concept to seamless deployment and ongoing maintenance—backed by a proactive, analytical approach.

As a Senior Full-Stack Engineer at K2, I lead end-to-end development of high-complexity Learning Management Systems, including scalable reward and gamification engines. I’ve driven multi-tenant architectures using PostgreSQL schema isolation, and delivered measurable improvements like a 25% increase in user retention and a 40% reduction in server response times through caching and query optimization.

Across web and mobile platforms at Flamingo Dev, I build responsive React experiences, React Native mobile applications, and Python/FastAPI backend services. I also develop RESTful and GraphQL APIs with authentication/authorization (OAuth 2.0, JWT), implement Redis caching, and support quality with unit, integration, and end-to-end testing using Jest, React Testing Library, and Cypress.
