Cloud Platform/DevOps engineer with 3+ years across DevOps, SRE and data engineering. Right now I'm the sole infra engineer for a US AI startup on contract, running AWS dev/staging and Nebius production. I cut dev/staging AWS spend from about $700/day to about $200/day, and recovered a corrupted production database using point-in-time recovery.

Before that I was the first DevOps engineer at GlueX Protocol, where I brought AWS spend down from about $25k to about $8.5k a month and ran the node and RPC infrastructure.

Looking for full time or contract platform, DevOps or SRE roles. Happy to overlap with US or EU hours and to take on-call.

3+ years in production infrastructure.

At GlueX, I helped reduce AWS spend from ~$25k to $8.5k/month and brought a critical request path from ~2s to under 250ms.

I’m now the first infrastructure person at an AI startup, owning AWS/Nebius infrastructure, deployments, observability, recovery and NVIDIA NIM/VSS workloads.

Platform / DevOps / SRE engineer with 3+ years of experience owning production infrastructure in startup teams.

I am useful when a team needs someone to take messy infrastructure, deployment, cost, observability, or reliability problems and make them boring.

Recent proof: At RestoreAI, I own cloud infrastructure for an AI product across dev, staging, prod, and preview. Recently reduced dev/staging AWS spend from about $700/day to $200/day by rightsizing GPU workloads and removing stale Kubernetes/ECS resources.

At GlueX Protocol, I worked on production blockchain/RPC and data infrastructure across multiple EVM chains. Reduced AWS cost by 45%, improved API latency from around 2s to under 250ms, and built observability with Prometheus/Grafana/Loki.

Platform / DevOps / SRE engineer with about 3 years of experience building and operating production systems in startup environments.

I work across cloud infrastructure, reliability, automation, observability, data infrastructure, and cost optimization. I have handled production infrastructure, monitoring, incident response, deployment automation, RPC/node infrastructure, benchmarking, and infrastructure migrations.

Most of my recent work has been at the intersection of platform engineering, blockchain infrastructure, data systems, and AI infrastructure. I am not limited to blockchain roles. I am also interested in platform engineering, DevOps, SRE, cloud infrastructure, data infrastructure, AI infrastructure, and technical operations roles.

Recent case study: https://www.krissemmy.com/projects/case-study-migrating-infr...

Best fit: early-stage or fast-moving teams that need someone who can own infrastructure, improve reliability, reduce cost, debug production issues, and build practical internal systems without needing too much hand-holding.
