• Creative Automation Tech — new team, new domain. Co-pitched the case for an AI creative-automation team to leadership, then transitioned my team into it. The team's mission is to automate ad-creative generation with AI, grounded in GYG's asset library (supplier, traveler, and creator content) and driven by marketing hypotheses, briefs, and motivators.
• Trip.com strategic launch & partner platform. Designed and shipped the partner-feeds platform that powered GYG's Trip.com launch. Within months, ~15 of our largest partners had adopted it, and the team now uses it as the reusable integration pattern 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–Jul 2026), Creative Automation Tech (Aug 2026–present).

• Acting EM — 2024 partner-tech rebuild. Led a 6-engineer cross-functional team (incl. 4 frontend engineers ramping into Java/Spring) through the hard-deadline PHP→Java/Spring migration of GYG's partner-tech backend. Owned planning, mentorship, and delivery. This work led to my promotion to Engineering Lead in Jan 2025.
• 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.

• 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).

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.

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 agent has its own MCP server, parent-driven Jira routing, autonomous polling loops, and one-PR-per-feature commit discipline.

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.

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 that use native and user-generated content to reshape the company's marketing pipelines.
