Hi, I'm Jonathan Matos 👋

Computer Engineer focused on DevOps, Platform Engineering, Cloud Infrastructure, and Software Engineering.

I work with cloud-native infrastructure, Kubernetes, CI/CD automation, Infrastructure as Code, observability, Linux systems, and distributed platforms. My experience includes production environments across AWS, Kubernetes, HPC/Slurm workloads, Web3 infrastructure, industrial IoT systems, and high-volume data processing.

I enjoy building reliable systems that connect infrastructure, software, automation, and operations.

Selected work

Cloud-Native HPC & Multi-Tenant Compute Platform

Worked on infrastructure components for a cloud-native compute platform involving Slurm-based HPC clusters, on-demand Kubernetes environments, JupyterHub, Keycloak, LDAP/Active Directory, Vault, Istio, CI/CD, and Infrastructure as Code.

Contributed to the migration from a single-tenant Kubernetes model to a multi-tenant architecture with shared platform services and isolated organization-level databases.

Globally Distributed Blockchain RPC Infrastructure

Designed and operated globally distributed Syscoin RPC infrastructure on AWS using ECS, Load Balancers, CloudFront, Terraform, and custom Nginx/Lua/JavaScript proxy layers.

The platform supported low-latency access, multi-region deployments, security filtering, wallet/contract allowlists and blocklists, monitoring, and traffic scaling to millions of requests per day at peak usage.

Industrial IoT Supervisory Platform

Architected and developed an end-to-end industrial IoT platform for real-time factory-floor monitoring using Next.js, NestJS, TypeScript microservices, VerneMQ, Kafka, gRPC, MongoDB time series collections, Kubernetes, and Docker Compose.

The platform was designed for cloud-agnostic and on-premise deployments, supporting high-volume telemetry processing and real-time supervisory dashboards.


Personal projects

Homelab Platform Manager

Building a self-hosted platform operations dashboard to manage services, deployments, domains, TLS certificates, health checks, infrastructure metadata, and operational status across Docker, virtual machines, and Kubernetes environments.

Local AI Infrastructure Lab

Experimenting with local and privacy-focused AI workflows using ComfyUI, Ollama, local LLMs, image generation models, and GPU-based inference. Focused on model deployment, workflow automation, dependency management, GPU resource constraints, and offline AI tooling.


GitHub activity

Most of my recent work involves infrastructure, platform engineering, automation, internal tooling, and private repositories. Public repositories here are mainly used for experiments, personal projects, learning, and selected open examples.
