I am an experienced Senior Software Developer with a strong background in healthcare, fintech, and IoT solutions. I led the development of a real-time medical benefit and pharmacy verification system, integrating XML data from TransUnion and JSON from Surescripts, and created APIs for medical and prescription benefit checks using Spring WS, Spring Batch, and Angular. I also worked on smart home solutions, including a smart door lock system using Node.js, React.js, and Firebase. In fintech, I played a key role in launching Nepal’s first wallet system, integrating multiple banks for money transfers and enabling bill payments, as well as transitioning monolithic architectures to microservices. I have hands-on experience with tools like Kafka, ActiveMQ, Jenkins, and Vault, and have managed CI/CD pipelines with Kubernetes and GitLab Runner. Additionally, I’ve implemented secure authentication protocols, including SSO solutions using Okta, Auth0, and Google Auth, and have led several successful offshore projects in healthcare, real estate, and IoT.

Backend software engineer with 4 years at Allstate India (global insurance & financial services), specializing in Java, Spring Boot, and microservices for regulated, high-availability, transaction-heavy systems.
What I do: I design and scale RESTful APIs, work across SQL and NoSQL databases (MySQL, MongoDB, Redis caching), and build cloud-native applications on AWS. I've designed 5+ Spring Boot microservices powering new insurance products, migrated services from PCF to AWS to improve scalability and cut infrastructure costs, and architected replay and performance optimizations that improved system efficiency by ~40%. My CI/CD pipelines in Jenkins have sustained near 99.9% production uptime.
What I bring to your project:
• Backend: Java (8/11/17), Spring Boot, microservices, REST API design & security, MySQL, MongoDB, Redis
• Cloud & DevOps: AWS, Docker, Jenkins CI/CD, Datadog observability
• Frontend: React.js, JavaScript (ES6+), Tailwind CSS — building UIs that consume my APIs
• Practices: TDD, code reviews, SonarQube quality gates, Agile/Scrum
I bring genuine engineering discipline: test-driven development, clean architecture, and documentation. I've consolidated legacy APIs into a unified architecture to reduce complexity, set up Datadog observability that cut production incidents through proactive alerting, and led knowledge-transfer sessions so teams can independently maintain what I build.
