Experience

Layered Schemas

https://github.com/cloudprivacylabs/lsa

Layered schema architecture is developed to work with unified data semantics regardless of the data capture locale, data representation, format, or terminology. Traditional schemas (such as JSON/XML schemas) describe the data structure with limited semantic information. Layered schemas use structural constraints similar to traditional schemas and open-ended semantic annotations to describe data.

Embedded Opencypher interpreter

https://github.com/cloudprivacylabs/opencypher

This is an embedded interpreter for openCypher graph query language in Go. This project also includes a high-performance labeled property graph implementation. It is based on a parser generated using the ANTLR4 system.

Took - OIDC Token Manager for Command Line

https://github.com/bserdar/took

An open-source token management tool for secure storage and maintenance of JWTs obtained from OIDC identify provider servers. This tool allows users to authenticate with a server to get an API token, stores that token on a disk securely encrypted, retrieves the token when necessary, and then refreshes the token as necessary.

Lightblue Platform

https://github.com/lightblue-platform

An open-source enterprise datastore platform using MongoDB as a back end. This platform aims to be a universal persistence layer to replace all storage back-end services for business objects. I designed and implemented the query and projection languages, metadata architecture, and multi-threaded join implementation. I also wrote most REST APIs that interface with the system, Java, and Go client libraries to connect and query the system with a fluent API.

Watermelon - Infrastructure as Real Code

https://github.com/bserdar/watermelon

Watermelon is a tool for building infrastructure as code. It lets administrators use a regular programming language (as opposed to some specialized scripting language) to connect to remote Linux machines, run commands, and copy files to manage configuration remotely.

Watermelon abstracts the details of accessing those remote machines. It is highly concurrent and uses gRPC to communicate with infrastructure-as-code scripts.

Jcliff - Incremental Configuration Management for JBoss/Wildfly Servers

https://github.com/bserdar/jcliff

Jcliff configures a running instance of EAP6, JBoss, and Wildfly using modular configuration files. It applies incremental configuration changes to a running server. It allows automated configuration of servers using Puppet, Ansible, and Chef.
