Platform Engineer & Founder

Ryan Scheinberg

I build the infrastructure other people depend on, for engineers, for AI agents, and now for the people studying for the hardest exams of their lives. At Bottomline, self-service platforms for 9 product lines. At Agent Horizon, I built SkillsCake and Reanthesis end to end.

About

At Bottomline, I am leading the company's move onto a self-service Akamai WAF platform, and I help guide AI engineering. The throughline of my work is taking something only specialists can touch and turning it into something any team can run safely.

On my own, I founded Agent Horizon and build its products end to end, from the first line of code to the marketing. SkillsCake does for AI agents what a good platform does for engineers: it hands them the context they need to do real work. Reanthesis is a turn toward people, a study app for brutal exams, designed with the nurses and med students who rely on it in production today.

Work

Staff Core Platform Engineer

  • Lead the company-wide migration onto Akamai as the CDN/WAF standard, bringing all product lines (some with 1,000+ hostnames) onto self-service GitLab CI OpenTofu pipelines my team built.
  • Help guide AI use across hundreds of engineers: shared skills on the skills.sh protocol, secure MCP servers, prompt-injection defense.
  • Replaced 3,000+ manual firewall tickets a year with validated, code-driven self-service automation.
  • Co-founded the GitOps Center of Excellence and helped build the internal product that made pipeline adoption easier.
  • Hosted office hours for 200+ users and mentored junior engineers.

Founder

Agent Horizon · 2025–present

Agent Horizon builds products, and I built every part of the business from the ground up, from full-stack development to marketing and support. SkillsCake makes AI agents faster and cheaper to run. Reanthesis turns grueling exam prep into something people look forward to.

Built

Reanthesis

re·anthesis: the repeated blooming of memory through recall. My own word, my own product. Bring your whole Anki library over clean, then study in something that finally feels good: grade each card with the addictive swipe of a dating app, and watch a little plant grow with every card's progress. Study rounds of 25 or 2 minutes are paced by a lupine that blooms as the timer fills. Nurses and med students study on it in production today and shape what I build. AI comes next, with care.

I wrote the parametric generator that grows this lupine in Python, so one program is the whole brand.

SkillsCake

Context engineering is hard, expensive, and out of reach for beginners. SkillsCake takes on that complexity and hands back a personalized, safe, and strong agent skill in minutes. You own your skill, and it runs across Claude Code, Cursor, and ChatGPT on fewer tokens. I treat SkillsCake as a security product: it defends against prompt injection, collects almost no data, and has no vendor lock-in.

I designed this minimalist mark, slice and all.

Plugins

SkillsCake is the best at improving a skill with zero context, but users wanted their agents to make skills with SkillsCake based on their actual work. The catch: a live conversation can carry PII and secrets. I made open-source plugins for Claude Code, Codex, and GitHub Copilot that safely run SkillsCake, optimally packaging and sanitizing the context. You get better skills without leaving your chat.

My Harness

An open-source agent OS for Claude Code. Reusable skills, subagents, and safety hooks, plus role-based sessions where a root operator spawns managers, a CEO, or specialized engineers to coordinate on a goal, with a human in the loop on the decisions that matter at multiple levels.

Beyond Work

Off the keyboard, I run Unicorn Hill Farm, with horses, daily chores, and heavy equipment. I'm an avid skier and an OEC-certified patroller at Whaleback. I have the cutest 1 year old German Shorthaired Pointer, and I cook both plant-based and animal-ingredient versions of recipes across cuisines.
