Solution Architect, active Maintainer and Contributor at OSDU (Open Subsurface Data Universe) data platform on behalf of Google Cloud Platform (GCP) cloud service provider (CSP). Playing key role in core, ingestion and consumption OSDU services onboarding, making architecture decisions for implementing and improving both Common and GCP code for Entitlements, Partition, Policy, Legal, Schema, Storage, Search, Dataset, FileDMS, WKS, Ingestion Workflow, Wellbore DDMS, WellDelivery DDMS and other OSDU services. As a maintainer, I provide community with architecture expertise and have a voting voice for common code reviews for MRs contributed by our (GCP) and other (IBM, MS, AWS) CSPs. Actively collaborating with DevOps and Cloud engineers I contribute my ideas, decisions and advice into cloud landscape, capacity and scaleability, CICD, repositories, Disaster Recovery planning and instantiating. Also, I take over technical communication and coordination on behalf of GCP team with other contributor teams and OSDU OMC and PMC representatrives. Those communications are in form of live meetings, Email and Slack threads, contributions in project documents composing etc. Part of my activities and achievements are well-traceable under my profile (https://community.opengroup.org/users/Rostislav_Dublin/activity) at OSDU community Gitlab where more than 750 ADRs (Architecture Decisions Requests), Issues, Merge Requests are authored, reviewed or commented of mine. My last personal achievement is an "Storage agnostic solution for NoSql(KV) data management" which is a Java library for mapping structured KV data produced/consumed by OSDU microservices onto the wide spread of available types of (cloud or on-premises managed) storages. Thus, those services become easily portable between different types of environments: cloud, mixed (eg. Anthos) or on-prem, without services code rework overheads.
