Andreas Schoinas

Staff Engineer & Engineering Manager

Zurich, Switzerland

Builder, manager, AI-native since 2023. Most of my output now ships through the teams I lead, the infrastructure I design, and the agent pipelines I orchestrate — less through my keyboard. Ex-CERN. Currently at GetYourGuide.

About

A Builder who happens to manage and architect. I've been using AI in my daily work since 2023 — one of the first at GetYourGuide to push it into production engineering, and I've spent the last three years compounding that lead. Today I spend less time writing code and more time designing the systems, agents, and pipelines that write it. My output isn't measured in commits anymore; it's measured in shipped products, leveled-up teammates, and infrastructure that lets a single person do the work of a team.

Background. 10+ years in Java/Spring, distributed systems, and platform engineering at GetYourGuide and CERN. Now applying that same systems-thinking to agentic workflows.

  • Agentic systems
  • Multi-agent orchestration
  • MCP
  • Prompt engineering
  • Claude Code
  • Java
  • Spring Boot
  • Observability
  • Event-driven

How I work

Design the org, not the work. Trovi's pipeline runs five named agents — PM, architect, developer, debugger, content — each with a role, an inbox, and an escalation path. The interesting choices aren't in any single prompt; they're in who owns what, where work hands off, and how routing recovers when something breaks. Same skill applies to humans.

Bet on infrastructure, ship through it. Six hours wiring up an agent loop pays back over months. At staff scale my default question is "what would let three more people (or agents) do this?" before "how do I do this?" — same calculus as hiring vs. shipping vs. building tooling.

Write down how you'd decide. The CLAUDE.md driving Trovi's agents is the same kind of artifact as a hiring rubric, an architecture RFC, or an on-call playbook — judgment encoded so the system can apply it without me in the room. The leverage isn't in making the call; it's in making the call repeatable.

Design for your absence. The systems I'm proudest of run without me — Trovi's pipeline ships PRs while I'm asleep, the on-call at GYG fires fewer pages than a year ago, the engineers I've hired make calls I'd have made myself. Presence is a constraint, not a feature.

Experience

Staff Engineer & Software Engineering Manager · GetYourGuide

Feb 2025 – Present

Builder. AI-native since 2023. I ship systems by orchestrating agents, not by typing every line.

  • Trip.com strategic launch & partner platform. Designed and shipped the partner-feeds platform that powered GYG's Trip.com launch — adopted by ~15 of our largest partners within months, and now the reusable integration pattern the team uses for every new strategic deal.
  • Localization platform reboot. Set the technical strategy and led execution for the localization platform reboot. ~50% lower ops cost and ~5–10% quality gains beyond top-4 languages, with knock-on effects across content, marketing, and supply teams.
  • AI-native engineering practice. Set the team's playbook for AI-assisted development, code review, and hiring in an AI era. Among the first at GYG to push AI into production engineering; now shaping how the function adopts it.
  • Associate engineer hiring track — adopted company-wide. Co-designed an Associate hiring pipeline that was adopted as the company-wide standard, opening a durable new talent funnel.
  • On-call & operational excellence. Inherited a noisy, debt-heavy on-call rotation and rebuilt it: ~90% alert-noise reduction and ~75% tech-debt burn-down inside a month. Pattern now used as a template by other teams.

Rotations: Partner Tech (Feb–Jun 2025), Localization Tech (Jul–Sep 2025), Marketing Platform (Oct 2025–present).

Senior Software Engineer · GetYourGuide

Mar 2023 – Jan 2025

Modernized the Partner Tech estate from legacy PHP to resilient Java/Spring Boot services.

  • Core domain library. Unified data access, authorization, and business rules; enabled consistent REST, GraphQL, and Kafka snapshot producers.
  • Public affiliate API migration. Moved inventory/availability/booking APIs to Spring Boot with zero production incidents and no partner disruption.

Software Engineering Fellow · CERN

Feb 2020 – Feb 2023

IT-CS-CT (Communication Tools): network data backbone and interfaces — from field technicians to DHCP and cluster/VM provisioning.

  • Framework modernization. Rebuilt legacy backbone into Spring Boot for maintainability and reliability.
  • PL/SQL → Java migration. Led the PL/SQL → Java migration of the TCP/IP address-management domain, zero production disruption.
  • Systems. CSDB (network infrastructure DB), LANDB (internet access portal), CernPhone (VoIP).

Earlier career · Cognity S.A. & Hellenic Army

2015 – 2020

Backend infrastructure for Cosmote / Payzy fintech and enterprise payments systems still processing hundreds of thousands of EUR daily. Database administration of mission-critical military systems.

Building with AI

Trovi AI · Solo build, in production

Cross-platform link-collection app (iOS, Android, Web) on Spring Boot + Flutter + MySQL. Built and operated by one person via a 5-agent Claude Code pipeline I designed: PM (Athena), architect (Archimedes), developer (Hephaestus), debugger (Asclepius), and content strategist (Calliope) — each with its own MCP server, parent-driven Jira routing, autonomous polling loops, and one-PR-per-feature commit discipline.

Agentic workflow infrastructure

Custom slash commands, hooks, multi-agent orchestration patterns, MCP server integrations (Jira, Confluence, Sentry, Figma), and prompt engineering for production reliability. Practiced equally on personal projects and at GYG.

AI adoption at GetYourGuide

2023 – Present

Early evangelist; helped shape internal practice on coding-with-AI, code review with AI, hiring in an AI era, and team-level adoption playbooks. Designed and implemented AI content creation tools to leverage native and user-generated content to reshape the company's marketing pipelines.
