Platform / DevOps / SRE engineer with about 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.

Projects: ShipCheck: deployment readiness checker for live web apps. https://shipcheck.krissemmy.com/

KraiNode: RPC diagnostics and benchmarking tool used by 450+ engineers. https://krainode.krissemmy.com/

Best fit: platform engineering, DevOps, SRE, cloud infrastructure, AI infrastructure, data infrastructure, production reliability, technical operations, or infrastructure-heavy support engineering.

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.
