I'm a Cloud Platform / DevOps Engineer with 3+ years of experience building and operating production infrastructure across cloud, AI, blockchain, and data-heavy systems.

I currently lead cloud/platform infrastructure at RestoreAI, where I own infrastructure, deployments, reliability, observability, security, databases, and GPU-backed workloads. Before that, I was a Founding DevOps & NodeOps Engineer at GlueX Protocol, operating production blockchain infrastructure across 15+ networks.

I like infrastructure work where the outcome is obvious: lower cost, lower latency, fewer failures, and less time spent babysitting systems.

• ~66% lower AWS spend at GlueX, from roughly $25k/month to $8.5k/month.
• ~8× faster production latency, reducing a critical RPC path from ~2s to under 250ms.
• Operated full/archive nodes and high-availability RPC infrastructure across 15+ blockchain networks.
• Reduced dev/staging AWS spend at RestoreAI from roughly $700/day to $200/day through GPU right-sizing and stale-resource cleanup.
• Built KraiNode, a multi-chain RPC diagnostics and benchmarking tool used by 400+ engineers.

• Cloud & Platform: AWS, Nebius, Hetzner, Terraform, Terragrunt, Docker, Kubernetes, GitHub Actions
• Reliability & Observability: Prometheus, Grafana, Loki, OpenTelemetry, SLOs, alerting, incident response, backups/recovery
• Blockchain Infrastructure: EVM JSON-RPC, full/archive nodes, RPC routing, failover, snapshots, node performance tuning
• Data & APIs: PostgreSQL, pgvector, MySQL, MongoDB, DynamoDB, Python, FastAPI
• AI Infrastructure: GPU workloads, NVIDIA NIM/VSS, workload sizing, deployment and cost optimization

A Python CLI for OpenAPI contract drift, safe live API checks, async job/webhook payload validation, retry handling, and CI-based reliability checks.

A deployment-readiness checker for live web apps covering HTTPS, reachability, response time, health endpoints, security headers, and metadata.

How I migrated a live startup across hosting, Redis, object storage, and databases while cutting recurring infrastructure cost and leaving behind a setup the team could actually operate.

I do infrastructure consulting for early-stage teams, mostly around cloud migrations, deployment systems, reliability, cost reduction, databases, backups, and operational handover. check out what some of my clients have to say consulting page

Outside work, I like music, trying new recipes, and building small tools that solve annoyingly specific engineering problems.

If you're building something where infrastructure is starting to become expensive, fragile, or distracting for the product team, that's usually where I'm useful.
