What I'm looking for

I'm looking to build production backend systems where I can own APIs, databases, security, and cloud deployment while growing with experienced engineers.

At Lemon Academia, I built the complete backend for a craft-supplies e-commerce platform as the sole developer, from database design and API architecture to Google Cloud Run deployment. I delivered 200+ REST API endpoints supporting product catalog, cart, and payments for 2,000+ daily customers.

I build secure Java and Spring Boot systems using PostgreSQL, JWT, role-based access control, OAuth, WhatsApp OTP verification, and Razorpay. My deployment workflow uses Docker and Google Cloud Run, reducing release turnaround to under 15 minutes.

I've also built Calmora, an AI-assisted mental wellness platform using Gemini AI, and Campus Connect, a college social and events platform with recommendation and post-ranking features. I enjoy solving data structures and algorithms problems and have completed 250+ on LeetCode.
