About

Software Engineer with hands-on experience building scalable backend systems, automating workflows, and integrating AI into real-world applications. Currently focused on backend engineering and AI-powered automation — designing systems that don't just work, but work intelligently. From RESTful APIs to LLM-powered job filtering agents, I build solutions that solve real problems with clean, production-ready code. I've shipped backend services handling 1000+ users, designed 15+ APIs that improved data flow efficiency by 30%, and deployed cloud infrastructure on AWS EC2 — all while keeping performance, scalability, and maintainability at the centre of every decision. What I bring to the table: • Backend: Java, Spring Boot, Python, FastAPI, REST APIs • Database: MySQL, PostgreSQL, JPA/Hibernate • DevOps & Cloud: AWS EC2, Docker, CI/CD, Git • AI & Automation: Google Gemini API, LLM integration, APScheduler • Tools: Postman, Maven, Git I'm driven by results, turning complex requirements into clean systems that perform well under real-world demands, whether that's optimizing a database query, shipping a robust API, or wiring AI into a core product. Always building. Always improving. 📩 sayandeepdutta41@gmail.com
