# Can (Jon) Yucel > Software Engineer at Sublime Security - Infrastructure Location: Mill Valley, California, United States Profile: https://flows.cv/canjonyucel Distributed systems, service mesh, Kubernetes, microservices, and all about the hype going on recently. Specifically experienced with devising cloud architectures from the ground up, building tooling around it, and tailoring opensource projects as needed. ## Work Experience ### Software Engineer @ Sublime Security Jan 2025 – Present | United States As an experienced Infrastructure Engineer, leading initiatives in cloud cost efficiency, improving the managed cloud solution, and working closely with enterprise customers to ensure smooth integration of the self-hosted product into complex infrastructure environments. ### Software Engineer @ DoorDash Jan 2020 – Jan 2025 | San Francisco Bay Area * As a Staff Engineer, helping DoorDash on its mission to be globally scalable, reliable, and secure at the edge. * Helped grow the Traffic team from 3 to 9 Engineers over the years. * Manage the relationships with the CDN vendor and Cloudflare through bi-weekly meetings, work on renewal agreements, coordinate yearly Executive Brief Review meetings, and connect with the product managers to discuss business needs. * Actively working on protecting DoorDash from bot attacks via Cloudflare WAF engine, meeting with internal teams to better understand their application behaviors to develop more sophisticated protection methods, and training the Traffic team to spread the mindset. * Helped DoorDash to save ~1.3M/year by deprecating the second WAF layer managed by the AppSec team. The work included getting a buy-in from the AppSec team based on the data, training them on Cloudflare, and collaborating with them on the migration. * As the first project at DoorDash, helped with designing and implementing the cell traffic architecture that allowed DoorDash to reduce blast radius during rollouts. The work included migration from Nginx to Envoy, including all service route configurations. * Since migrating to the new cell environment was operation-heavy work, we introduced automation that helped people switch between migration states via a UI. The work involved updating our existing Kubernetes Controllers via new APIs. To achieve this, we collaborated with our sister teams. * Conducted sprint planning, daily meetings, and retrospectives on the Traffic team. ### Senior Software Engineer @ Cruise Jan 2017 – Jan 2020 | San Francisco Bay Area * As one of the original members of the PaaS team, I helped grow the team from 4 to 30+ engineers. * Pioneered the GCP migration at the company and was involved in designing the hybrid cloud architecture that included the design of multi-tenant Kubernetes clusters, NAT gateways, load balancers, and CIDRs. * Provided multi-cloud DNS infrastructure via CoreDNS, spanned AWS and GCP. Contributed to the open-source project by extending its Route53 plugin capabilities. * Designed and implemented a Kubernetes controller that enabled black box monitoring for the workloads running on our clusters on day 1. * Led the Istio/Service Mesh project at the company to improve the multi-tenant clusters' overall reliability, visibility, and security stance. * Enabled cross-cluster service authentication for Kubeflow Pipelines (KFP) APIs through Istio and developed a tool for injecting Istio sidecars into KFP short-lived jobs. ### Architect @ GLIDR Jan 2015 – Jan 2017 | San Francisco Bay Area * Architected a scalable containerized microservice infrastructure from the ground up, which included the design of backend services, libraries, AWS networking structure, and Kubernetes clusters. * Led the engineering team of 10 and helped them to produce production-grade code with code reviews, pair programming, and tech talks. Although I was a core employee at the company, after my departure, the team was able to keep improving the code base with the long-term vision they had. * Architected the CI/CD pipeline by leveraging CircleCI, Kubernetes namespaces, and Helm, which helped the QA team to provision test environments through a Slack bot within minutes. * Developed a MongoDB query generator and built helper packages to ease and expedite backend service development. * Implemented a scalable and robust reactive real-time messaging infrastructure to provide async communication between services and end users with RabbitMQ and Go. ### Software Engineer @ Koding Jan 2013 – Jan 2015 | San Francisco Bay Area * Got experience around microservice architectures by replacing monolithic Node.js architecture with REST-based microservices. The experience later helped me design more complex software architectures that ran in the cloud. * Replaced existing messaging system with no downtime with a fully scalable and robust architecture backed by RabbitMQ and Go. * Implemented scalable notification and emailing infrastructures backed by Redis, RabbitMQ, and PostgreSQL. ### Lead Backend Engineer @ Tart New Media Jan 2011 – Jan 2012 * Architected the backend infrastructure of playstore.com with REST-based APIs. The design was backed by UML diagrams. * Architected and implemented a SQL generator and a flexible indexing mechanism, which improved the team's development speed. * Trained the team on design patterns and software engineering through the in-house summer camp program. (PHP, Zend Framework) ### Researcher @ TUBITAK Jan 2009 – Jan 2011 | Kocaeli, Türkiye * Developed a graphical user interface and plugins for a Submarine Tactics Simulator by collaborating with the Turkish Naval Forces. As a fresh, out-of-college engineer, I quickly adapted to the project and finished development way earlier than the given deadlines.
