Photo of me having fun at a party.

I'm a results-driven Senior Software Engineer with 9 years of hands-on experience designing and building cloud-native projects.

Specialized in crafting high-throughput applications using modern technologies across the entire back-end stack, like NodeJS, Typescript, MongoDB, PostgreSQL and Kubernetes.

Throughout my career, I have consistently demonstrated the ability to successfully tackle and deliver impactful projects, leaving a distinct fingerprint on each endeavor.

    Created and maintained Github Actions configuration files for building and testing as well as Helm Charts & Kustomizations deployed on ArgoCD to sum up for an end-to-end CI/CD process.

    Improved build times by more than 80% while also scaling down image sizes by an entire order of magnitude by leveraging Github Actions concurrency and caching as well as Docker multistage builds and distroless images.

  • Bitdefender

    -

    Worked on building an internal platform that enabled developers and ML researchers to easily manage their code's lifecycle after development, from building, to deploying to multiple testing and staging environments and ultimately going to production.

    Implemented multiple Kubernetes operators for technologies such as RabbitMQ, Prometheus and the Elastic Stack (deep diving into operations like HA clustering, sharding, etc.) in order to be able to ship them as managed services.

    Designed and implemented a hardware and software discovering and inventorying system that in only a couple of months helped the company pass a SOC2 audit while also saving on alternative paid solutions.

    Designed and implemented a highly-available, multi-region mail templating gateway through which the client emails are being sent on behalf of the products. Built, managed and worked with multiple message brokers and SMTP gateways connected on a multi-region scale, on high-availability requirements.

    Participated in the design and implementation of infrastructure, Kubernetes deployment on public and private cloud providers (Google Cloud Platform, Amazon AWS and on-premise infrastructure) as well as migration (Virtual Machines to Kubernetes), replication, scaling and authentication of services like MongoDB, RabbitMQ, Redis and Elastic Stack components using OAuth2.0 flows.
