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.

Full-stack software engineer who enjoys solving difficult technical problems and building systems that are reliable, maintainable, and useful. My experience spans full-stack development, API integrations, workflow automation, and quality engineering, and I'm particularly drawn to understanding complex systems and improving how they work.

I am extremely analytical and logical, but also very creative, socially outgoing, and comfortable operating across a very wide range of disciplines. (For example, although I am a strong coder, I also have excellent oral and written communication.) Because I think in terms that are concrete but conceptual, I excel both in technical and non-technical environments, and beyond software development, I've also been involved in workflow automation, technical communication, and QA. I'm a very fast learner and I'm always willing to explore new technologies/better ways of doing things.
