Included calling suppliers, pricing, providing management writeups on cost projections and cost/benefit analysis along with writing the software package.
  • Deployed a K3S cluster over the DMVPN networking using calico CNI, to manage a global deployment of remote network devices for satellite/gnss monitoring.
  • Created custom exporters that supported prometheus, InfluxDB, and Loki, which were in turn visualized in Grafana setup which was surfaced in a multitennet environments for outside B2B customers .
  • Setup an entire Thanos setup (I can physically draw this on request, too much to type here as the multi-tenecy is a lot to write about)
  • Designed, built, tested, and maintained several critical APIs which supported the core business product.
