Software Developer • Java Engineer • Founder
I am a software developer from Nepal and the founder of A1 IT Innovation Pvt. Ltd. I build backend systems with Java and Spring Boot, the infrastructure that runs them, and the web and mobile applications that sit on top.
What I build
Most of my work is on the server side. I build services in Java with Spring Boot, design REST APIs for web and mobile clients, and model data in MySQL.
Java · Spring Boot · REST APIs · MySQL
When one service is no longer enough, the hard part is how the pieces communicate. I work with microservice architectures, Redis for fast in-memory data, and Kafka and RabbitMQ for asynchronous messaging between components.
Microservices · Redis · Apache Kafka · RabbitMQ
I also handle deployment and operations: packaging services with Docker, running them on Kubernetes, automating builds and deployments with GitHub Actions, and managing cloud and server infrastructure.
Docker · Kubernetes · CI/CD · GitHub Actions · Cloud / server infrastructure
Backends need clients. I build cross-platform mobile applications with Flutter and web interfaces with React, so I can work across the whole product.

I think about how services, databases, caches and message brokers fit together, and about the trade-offs between consistency, latency and operational complexity.
System design · Software architecture
I experiment with AI and machine learning, particularly language models, multilingual embeddings and Nepali language processing. See the research page for what I am interested in.
LLMs · Embeddings · NLP
