I build secure, scalable backend services and product integrations in Java and Node.js.
AlbaniaWhat I'm looking for
I've built and maintained backend services for Clockify at CAKE.com, supporting a large-scale time-tracking and productivity platform.
I developed integrations across Clockify, Plaky, Pumble, and the CAKE.com Account platform using Apache Kafka, webhooks, REST APIs, Java, Spring Boot, and MongoDB. I also investigated production issues with Grafana and improved distributed-service reliability through debugging and refactoring.
At TeamSystem Tirana, I built analytics APIs and services in Node.js, NestJS, Java Spring Boot, MongoDB, and PostgreSQL. I integrated Databricks, Azure Key Vault, and Witboost while deploying containerized services to Kubernetes through GitLab CI/CD.
Earlier at Sirma SHA, I created REST APIs, database schemas, Jasper Reports, and backend business logic for micro-finance and state exam applications. I enjoy building robust systems and exploring cybersecurity and penetration testing.
