Segun – Ansible, Kubernetes, Docker

A platform that automates deploying and operating distributed services, primarily blockchain nodes and infrastructure, across multiple cloud providers.

• Built an open-source monitoring agent forked from Grafana Agent, with chain-specific metric collection, and shipped it as the default agent across the platform.
• Developed the core SSH module that powered automated deployments across blockchain and stateful workloads.
• Rebuilt internal observability into a unified OpenTelemetry architecture with agent and gateway layers and Kafka buffering.
• Owned multi-tenant Kubernetes platform architecture for 20+ clients with policy enforcement, network debugging, ingress, and GitOps.
• Designed Telescope Cloud authentication and rate-limiting for telemetry endpoints using Envoy Proxy and a custom verification system.
• Defined SLOs, built Grafana SLIs, and used error budgets to gate releases and prioritize reliability.
• Developed Helm charts with automated health checks for multiple application types.
• Designed Grafana dashboards for root cause analysis and system health monitoring.
• Managed client production infrastructure across blockchain networks and database clusters on Kubernetes.
• Handled 24/7 on-call via PagerDuty and wrote post-mortems and RFCs for major incidents and infrastructure changes.
• Optimized Kubernetes clusters by right-sizing workloads and cleaning up unused resources.
• Architected HA RPC nodes on Kubernetes for reliable WebSocket connections.
• Managed secrets with HashiCorp Vault, enforcing RBAC and credential rotation.
• Wrote automation scripts and pipelines for cluster provisioning, certificate rotation, log cleanup, node restarts, and new client environment setup.
• Mentored an intern engineer through an 8-month term.
• Wrote technical documentation for deployment and maintenance procedures.

An AI-driven crypto analytics platform.

• Set up CI/CD pipelines with SonarQube quality gates and automated checks.
• Set up observability across the stack using OpenTelemetry and SigNoz for application and infrastructure monitoring.
• Migrated core applications to Microsoft Azure while keeping the existing DigitalOcean infrastructure highly available.
• Optimized cloud infrastructure costs across Microsoft Azure and DigitalOcean through right-sizing and cleanup of unused resources.
• Automated production rollouts for new features with zero-downtime deployment strategies.
• Supported the data team’s Airflow and analytics infrastructure.

A blockchain infrastructure platform that deploys, runs, and monitors Filecoin nodes and other distributed services with an emphasis on reliability, simple deployment, and fast recovery from failures.

• Built CI/CD pipelines with GitHub Actions, including automated linting, testing, and quality checks.
• Optimized AWS infrastructure by eliminating unnecessary servers and using spot instances.
• Set up end-to-end monitoring with New Relic, Grafana, Prometheus, Loki, and PagerDuty.
• Automated snapshot management for Kusama and Polkadot nodes using Python and Amazon S3.
• Maintained and optimized bare-metal servers and built custom Ansible playbooks for provisioning, patching, and configuration management.
• Deployed Kafka for event streaming on Golang-based platforms, PostgreSQL for data management, and IPFS clusters with custom replication policies.
• Created reusable Terraform modules for standardized deployment across AWS, GCP, and Hetzner.

n observability platform that collects logs and metrics from multiple Kubernetes clusters and centralizes them in one place.

• Designed production-grade EKS clusters using Terraform and Terragrunt.
• Built a unified monitoring stack with Grafana, Prometheus, Alert Manager, and CloudWatch.
• Developed Kubernetes autoscaling to reduce infrastructure costs and improve peak performance.
• Implemented serverless applications using AWS Lambda, API Gateway, and DynamoDB.
• Tightened container security with ECR scanning, Aqua Security, and automated vulnerability patching.
• Ran post-mortem analyses to reduce bugs and speed up debugging.
• Set up disaster recovery procedures.
• Designed and deployed Helm charts and Terraform configurations for optimized network deployment on AWS.

Internal back-end and infrastructure projects supporting telecom systems and developer workflows.

• Created API documentation using Swagger/OpenAPI.
• Built Grafana and Prometheus dashboards for application metrics.
• Contributed to migrating legacy applications to Docker.
• Developed automation scripts in Python and Bash for server provisioning and configuration management.
• Set up CI/CD pipelines using Jenkins and created Ansible playbooks for automated server configuration.
• Implemented infrastructure as code for cloud test environments.
• Assisted with ISO 9001 compliance.
