About Me
Software Development Engineer specializing in backend engineering, scalable architecture, and full-stack product development.
4+ yearsJaipur, Rajasthan, India
I'm Deepak Nayak, a Software Development Engineer with around 4 years of professional experience building scalable, secure, and high-performance web and mobile applications. I specialize in backend engineering and full-stack development, with a strong focus on designing reliable systems, developing robust APIs, and solving complex technical challenges.
My professional journey spans product-based and enterprise application development, where I've worked with Node.js, NestJS, Express.js, React.js, Next.js, React Native, TypeScript, JavaScript, MongoDB, and MySQL. I have hands-on experience in backend architecture, RESTful APIs, database optimization, authentication and authorization (JWT/RBAC), Redis caching, real-time communication, and cloud technologies. I've contributed to developing and maintaining LMS, ERP, CMS, e-commerce platforms, mobile applications, and large-scale management systems.
I'm passionate about building scalable backend systems, optimizing application performance, and developing reliable software solutions. I also work with AI platforms such as OpenAI and Google Gemini, and use AI development tools including Cursor AI, Cloud AI, GitHub Copilot, and OpenAI Codex as part of my engineering workflow. My experience includes payment gateway integrations, Firebase services, AWS, CI/CD workflows, and third-party API integrations. I believe in writing clean, maintainable code, following best engineering practices, and continuously improving software quality. I've also been recognized with a Performance Award for my professional contribution.
