About Me

I’m a backend engineer with over 4 years of experience designing and implementing scalable, secure backend systems. I specialize in building RESTful APIs, database-driven applications, and maintainable backend architectures using Node.js, Express, NestJS, MongoDB, and PostgreSQL.

I’ve worked with startups across FinTech (B2B SaaS), Travel Tech, Marketplace, Social Media Platforms, and E-commerce, delivering backend systems that power web and mobile applications. My focus is on building maintainable architectures, optimizing performance, integrating third-party services, and deploying cloud-native solutions on AWS and Azure.

Beyond coding, I emphasize clean architecture, scalability, and maintainability, working closely with product and frontend teams to ensure backend solutions align with business goals and support long-term growth.

Outside of work, I enjoy knowledge sharing, reading, watching movies, and traveling for adventure.
