I'm Ruslan Mustakimov, a backend engineer focused on Java, distributed systems, data platforms and practical performance improvements.
I design, build and maintain backend services—from API development and workflow automation to integrations, data processing and production troubleshooting. I care about clear architecture, reliable delivery and measurable outcomes.
Developed and maintained a data catalog platform, workflow and approval processes, integrations and metadata ingestion pipelines.
Contributed to the design and evolution of backend architecture, refactored existing services, and designed workflow-driven solutions for entity drafts, approvals, and access management.
Built backend features for a time-tracking platform and fintech products, including REST APIs, authentication, reporting and external integrations.
Helped streamline Jira-based time tracking and customer invoicing workflows.
A location recommendation platform that helps people compare places to live based on their priorities. Built with Java, Spring Boot, MongoDB, Kubernetes and Helm, with indicator-based scoring and external data integration.
