Part of a small seed stage company that builds a simple to use tool that extends kubernetes to make it simple to run sandboxed workloads. This allows faster developer velocity when building in a large microservice environment* Implemented the API portion of the new Resources feature that allows easy attachment of k8s resource types (like Databases)* Implemented UX improvements to the React based API* Help test our kubernetes operator and extensions to support the creation of sandboxes.

My main role is assisting other development teams build new interconnected microservices or help existing solutions move to a more distributed model. As a member of the Events Platform, I am responsible for the underlying Kafka infrastructure, designing the common message schema, developing shared libraries (python, java, nodejs, and go) and finally mentoring teams on how to best utilize pub/sub async communication patterns. I spend a lot of time mentoring, coaching and teaching other teams on Domain Driven Design and architecture, which is essential for building a distributed system and liberating data.* Organized and lead Carta only engineering seminar series on domain driven design and architecture. Attendance over the scope of the program has been 60+ engineers.* Strong advocate and mentor on pub/sub communication patterns, microservice architecture, DDD and Kafka* Created a declarative based approach to managing Kafka API keys, ACL permissions and Kafka topics based on derivation of protobuf message schemas, terraform and Kubernetes operators* Implemented Helm based sub package that allows individual developers and teams to deploy Kafka Connect infrastructure easily on the company’s cloud* - Design and delivered a custom Kafka operator written in Go that allows Kafka Connectors to be managed in a declarative fashion using Kubernetes CRDs with Vault secrets integration* Lead discussion and presentations on the best practices for introducing Kafka into existing and new services* Developed Python, Go and Java based common libraries for Kafka (based on our serialization best practices and protobuf) in addition to sample application showing usage of Kafka* Lead collaboration on design the message serialization format based on protobuf to best integrate with existing gRPC technology and integration with the CloudEvents cloud native standard

During my time at Cover I wore the architect hat by mentoring the team in sound API design and architecture patterns. My focus was split on the following sections:* API Design: I led an architecture revamp of the entire quoting system and focused multiple delivery teams on: Payload standardization, documentation to decrease failure and design drift"* Document design: I spear headed the engineering org on a "Document first" initiative where our internal APIs would be written, signed off by consuming teams and published before code was written to reduce latency in adoption of the new APIs* Promoted API document driven design by implementing a company wide policy using OpenAPI (Swagger), later GraphQL, to document API prior to development.* Architected the transition from two siloed (include functional duplication) monolithic rails services to microservices. The new system is a combination of ruby and Go (golang) services that communicate with each other through traditional HTTP/REST but also gRPC and events based on the cloudevents standard.* Architected an event driven system, including mentoring senior, intermediate and junior devs on this pattern* Design an automated CI/CD delivery pipeline that follows gitops.* Built a go microservice chassis that allows all go services in the company to be standardized leading to fast development.
