I constantly Planned, Owned the infrastructure, continously developed and implemented DevOps strategy that scaled and improved the efficiency of the peer-to-peer distributed systems infrastructure. Collaborated weekly with Developers, Infrastructure teams, Heads and Lead to improved the infrastructure to meet business needs using Devops principles. Migrated Datadog Logs, monitoring to Loki and Grafana while preserving the existing custom metrics, Logs formats for Sprinter and Sygmaprotocol distributed systems. Designed, built, maintained OpenTelemetry Agent shipping Logs from nodes on Sygma, Sprinter, Partners (distributed systems) to Loki server. Designed, Devloped and built serverless applications with Python on AWS Lambda to ship logs from SNS Topics to Loki server, visualize with Grafana. Developed customs PROMQL queries that implemented (the existing Datadog Logs views, fields, streams) on Grafana for monitoring of distributed systems, while keeping account of low query cost. Designed and implemented GitOps principles for Sprinter infrastructure. Redesigned, Scaled infrastructure and reduce the cost of logging on AWS Cloudwatch by 250% and total infrastructure cost by 50%. While I improved GitHub Security, I segregated the environments secrets that can only be accessible to specific environments (Devnet-to-Devnet, Testnet-to-Testnet & Mainnet-to-Mainnet). I planned, designed modular infrastructure for Sprinter Tech, implemented the Infrastructure as Code with Terraform, and developed Terraform custom modules for speedy provisioning of infrastructure as code, reduce repeatable code, and with less codes means less error.
