I worked professionally with Go over 4 years, since 2019.
I am very confident in designing, writing and reviewing Go code.
You can check my many Go open-source repositories on my Github.

I did an API to integrate with ImageMagick and ffmpeg, to render videos from a queue inside Google Cloud.
    

I used TypeScript for 2 years, for Raccoon Digital Marketing and for freelancing.
I am very fond of static types, as it avoids simple errors during compilation time.
I consider myself pretty experienced with statically typed systems, and prefer using TypeScript whenever possible.
    

I am very proeficient with Mongo, as I studied and received plenty of consultancy for it.
I did heavy workflows under it, aggregating and upserting data from pipelines, doing complex aggregation pipelines,
usage of Geo-filters, Bucketing, etc.
    

I used Postgres for over 2 years, professionaly and in pet projects.
I studied about data normalization and relational data in general.
I am not confident in large scale utilization of Postgres, and might need to study before doing so.
    

I did plenty of observability and monitoring with Grafana + Prometheus.
I developed useful dashboards for monitoring availability and resource usage for web-services.
    

I did 2 years of professional usage of ReactJS, including freelancing.
I used it for SPA and an e-commerce page.
I am well familiarized with the component life-cycle and react-hooks.
    

I used Kubernetes all my career, I can't conceive the development of a complex cloud system without Kubernetes.
I know how to retrieve information, control releases, manage deployments and horizontal scaling.
I prefer using the tool k9s for interacting with Kubernetes locally, increasing my efficiency a lot.
