What I'm looking for

I'm looking to build modern Android applications or scalable Java backend systems, applying Clean Architecture, MVVM, Spring Boot, databases, and AI-assisted search in end-to-end product work.

I've built ForensiX, an AI search backend that helps investigators find facts hidden across PDF, DOCX, CSV, and TXT case evidence.

I designed its asynchronous ingestion pipeline using MinIO, Apache Tika, PostgreSQL, and pgvector, including deduplication and automatic rollback on failure. I also built hybrid search through raw JDBC and PostgreSQL, and integrated Llama 3.2 through Ollama and Spring AI for structured, grounded responses.

I also built NepSmartPay, a Kotlin and Jetpack Compose Android app that generates Smart QR codes for temporary Wi-Fi access and local payment routing. Its QR parser supports EMVCo, UPI, and JSON bank formats, while the payment router detects compatible wallet apps such as eSewa, Khalti, and Fonepay.

I'm a Computer Science & Engineering graduate focused on modern Android development, enterprise Java backends, clean architecture, and end-to-end product development.
