About Candidate
I am a Software Engineer with experience building secure, scalable web and backend systems across fintech, payments, lending, and service platforms.
My experience spans backend development, API design, payment and transaction workflows, ledger systems, authentication and authorization, and data-driven applications. I primarily work with Python/Django, TypeScript/NestJS, React/Next.js, and PostgreSQL, with hands-on experience using Docker, AWS, CI/CD, Redis, and RabbitMQ to build and deploy reliable systems.
I am particularly interested in the engineering challenges behind financial and transactional systems, maintaining data consistency, designing secure APIs, handling asynchronous processes, integrating payment providers, and building architectures that remain reliable as systems scale.
I enjoy working on complex backend and full-stack problems and turning business requirements into well-structured, maintainable, and production-ready software.
