What sushiroll.io does

sushiroll.io is the personal portfolio and creative technology studio of Katie Hemus, a Staff-level AI Infrastructure Engineer based in Manchester, UK. The site functions as a professional portfolio and a working demonstration lab rather than a formal commercial entity: there is no incorporated business, no investor base, no pricing model, and no named external customers. The core technical artifact is OpenClaw — a production AI operations platform running on a single VPS that combines a multi-model LLM gateway with failover routing, an agent orchestration engine for parallel task delegation, 87 skill-based tool integrations, and RAG-powered semantic memory, alongside a local voice pipeline (faster-whisper for speech-to-text, Piper TTS for synthesis) with no third-party audio dependencies.

Beyond OpenClaw, the portfolio spans a range of deployed projects. At PortSwigger, Hemus built the LLM Gateway serving as the AI backbone for a flagship security product, routing chat, embeddings, and RAG calls through LiteLLM on Kubernetes (EKS) with Helm, Prometheus, and Grafana Loki; this work cut deploy cycles from two weeks to minutes and CI/CD runtimes by 95%. An internal RAG system over engineering documentation was built in early 2023 before RAG was a named category and was adopted by tech support for customer FAQs. Side projects include the micethateatcake autonomous Etsy shop (publishing a new AI-designed digital product daily), Tidbit Tails YouTube and TikTok channels (end-to-end automated content via Sora-2, Whisper, TTS, ffmpeg), a Spotify Wrapped clone, a Job Hunting Board career-ops dashboard, and several creative web experiences (Elysian mythology site, Howl's Bedroom CSS art, Mood Board tool, Mora band site, Nomic Atlas tooling map).

The business model is effectively a personal-services positioning vehicle rather than a revenue-generating business. Commercial revenue mechanics are limited to Etsy digital-product sales and potential content monetization on YouTube/TikTok; the strategic purpose of the portfolio is to support a transition into a Staff or Principal AI infrastructure role, and Hemus is currently employed as a Senior Platform Engineer at Civica championing AI adoption company-wide. The entity is not venture-fundable in its current form, but its underlying operator is demonstrably operating at a senior IC level in production AI infrastructure.

Core offering

sushiroll.io is a personal portfolio and creative technology studio that showcases AI infrastructure engineering work and a portfolio of side projects. The core technical artifact is OpenClaw — a production AI operations platform with a multi-model LLM gateway, agent orchestration engine, 87 skill modules, RAG-backed semantic memory, and a local voice pipeline — alongside a portfolio of autonomous commerce, content, and creative web products built on top of it. The site is not a commercial product company; it is a portfolio/resume site for a Staff-level AI Infrastructure engineer.

Product overview

sushiroll.io is a personal portfolio and creative technology studio led by AI Infrastructure Engineer Katie Hemus. The core platform is OpenClaw — a production AI operations system built on a single VPS, combining a multi-model LLM gateway with failover routing, an agent orchestration engine, 87 skill-based integrations, and RAG-powered semantic memory, all tied together with a local voice pipeline. The LLM Gateway serves as the AI infrastructure backbone for flagship security products. Beyond OpenClaw, the studio's portfolio spans autonomous commerce (micethateatcake on Etsy), AI-driven content production (Tidbit Tails on YouTube and TikTok), data visualisation (Wrapped Spotify clone), career automation (Job Hunting Board), and creative web experiences (Elysian mythology site, Howl's Bedroom interactive art, Mood Board curator, Mora & the Fabulous Wonderfuls band site). Infrastructure tooling includes the Nomic Atlas-powered tooling map for AI stack visualisation.

Products and services

• OpenClaw AI Platform A production AI operations platform running on a single VPS, featuring a multi-model LLM gateway with failover routing, an agent orchestration engine for parallel task delegation, 87 skill-based tool integrations, and RAG-powered semantic memory, plus a local voice pipeline. Designed and built for personal automation of Etsy, YouTube, Notion, and TikTok workflows.
• LLM Gateway Central AI platform routing every LLM call (chat, embeddings, RAG) through a single gateway with model failover, rate limiting, cost attribution, and audit logging. Multi-tenant, serving both product and internal tools. Built with LiteLLM, Kubernetes (EKS), Helm, Prometheus, and Grafana Loki.
• Internal RAG System A Q&A semantic search system over engineering documentation, built using vector embeddings and retrieval-augmented generation. Initially built for engineering teams; adopted by tech support for customer FAQs and nearly deployed as the website's documentation search.
• Scan Template Generation AI-powered template generation for vulnerability scans — users describe what a scan needs to do in natural language and receive a working template. Shipped as an AI feature in PortSwigger's flagship product.
• micethateatcake (Autonomous Etsy Shop) An autonomous Etsy shop that designs, builds, tests, and releases a new AI-generated digital product every day (planner packs, service contracts, onboarding kits, printables) with no human in the loop from research to publish.
• Wrapped (Spotify Wrapped Clone) A pixel-perfect rebuild of the Spotify Wrapped year-in-review experience with animated data visualization and shareable stat cards, built with Google Stitch Studio.
• Job Hunting Board A password-gated career operations dashboard that ingests LinkedIn CSV exports, maps the user's professional network, identifies warm introduction paths to target companies, and tracks roles, recruiters, scoring criteria, and interview stages.
• Mora & the Fabulous Wonderfuls Website A dark stage-lit portfolio website for a Manchester-based live band, featuring full-bleed gig photography, a masonry gallery, dynamic gig listings, and a backend admin API with drag-and-drop media uploads.
• Elysian An immersive Greco-Roman mythology experience featuring painterly temple scenes, vintage engraving-style illustrations, AI-generated artwork, and interactive hotspots revealing god myths.
