About
I’m Zaiba Nikhat, a backend engineer with 4.3 years of experience building scalable microservices and REST APIs for enterprise telecom systems. I specialize in Java and Spring Boot, and I’ve delivered TM Forum–compliant APIs using both contract-first and code-first approaches.
In my recent work, I focused on reliable API design, resource modeling, validation, and transaction-safe behavior, including optimistic locking to handle concurrent edits. I also enjoy improving developer and deployment workflows with automation, and I’ve worked across security and DevOps practices using JWT/RBAC, Docker/Kubernetes, and monitoring tools to keep services dependable in production.

Work experience
Developing REST APIs for British Telecom (IP Address Management) using Java 21, Spring Boot 3, Spring Data JPA, and PostgreSQL to manage IP resources and lifecycle. Implementing code-first REST endpoints with request/response models and business logic, including Java 21 performance-oriented features. Added optimistic locking to prevent lost updates during concurrent subnet editing and to return field-level conflict details. Secured APIs using JWT authentication with role-based access control (Admin, Super User, User). Supported deployments and monitoring with Docker, Kubernetes, Kong Ingress, HashiCorp Vault, and Dynatrace; collaborated with frontend teams to align API contracts and end-to-end feature delivery.
Delivered 10+ TMF-compliant REST APIs for Deutsche Telekom (TMF API Development) using Java and Spring Boot. Followed a contract-first (OpenAPI/Swagger) workflow to define API specifications, schemas, and validation rules prior to implementation. Translated telecom OSS/BSS requirements into consistent API contracts and resource models for integration across systems. Partnered with architects and stakeholders on API design, low-level design, and implementation through Agile sprints. Refactored backend components and created Python automation scripts to streamline deployment workflows.
