I build Java and Node.js backend systems for fintech, biotech, and graph-data platforms.
ArmeniaWhat I'm looking for
I've built backend systems for Optimum Partners, BostonGene, and Cognaize, spanning graph-data platforms, biotech services, and fintech products.
At BostonGene, I engineered Java 21 and Spring Boot services, integrated Kafka messaging across microservices, supported Apache Airflow and Python ETL workflows, and automated testing and deployments with GitLab CI/CD.
Most recently, I've built GraphQL APIs and Neo4j data models with Node.js and TypeScript, optimized Cypher queries, and defined frontend-backend API contracts. I focus on maintainable, testable code and contributing to architecture early.
